Rhinosporidiosis

Rhinosporidiosis is a long-lasting infection that mainly grows on moist lining tissues of the nose, throat, and eyes. It is caused by a microscopic organism called Rhinosporidium seeberi. This organism is not a typical fungus or a typical parasite; it belongs to a special group of water-associated creatures called Mesomycetozoea (also named Ichthyosporea). The organism enters through tiny breaks in wet mucous membranes, settles there, and slowly forms soft, red, polyp-like growths that often bleed easily. Under the microscope, doctors see round “sporangia,” which are tiny sacs filled with many small spores. This look is very characteristic and helps confirm the diagnosis on tissue examination. Scientists have not been able to grow this organism in routine laboratory culture, so diagnosis depends on looking at tissue and, where available, using molecular tests that detect its genetic material. ASM JournalsPMC+1ScienceDirect

Rhinosporidiosis is an infection that usually makes soft, red, polyp-like growths on moist inner surfaces of the body, most often inside the nose and the area behind the nose. The growths look “strawberry-like” because they are pink or red with many tiny white dots on the surface. Those little dots are the sacs (called sporangia) that hold the organism’s spores. The infection bleeds easily when touched, so people often notice nosebleeds, nasal blockage, or a slowly growing mass. The disease is caused by Rhinosporidium seeberi, a water-associated, eukaryotic microbe in the Mesomycetozoea group (also called the “DRIP clade”), which is neither a classic fungus nor a bacterium. People most often get exposed in warm climates after contact with stagnant pond or river water. The gold-standard diagnosis is a biopsy that shows the round sporangia under the microscope, and the main treatment is surgical removal of the mass with cauterization of the base to reduce the chance of coming back. Medicines help only as add-ons in selected situations, and dapsone is the best-studied adjunct to lower recurrences, although even that evidence is limited.

Where and how people get it

People usually pick up the organism from natural water sources such as ponds, lakes, and slow-moving rivers. The infection is most common in parts of South Asia (for example, areas of India and Sri Lanka) where bathing, swimming, or washing in village ponds is a daily habit. Small injuries in the nose or eye area can let the organism in during these water exposures. The disease often shows up as a red, “strawberry-like,” bleeding polyp inside the nose, but it can also affect the eye surface, the tear sac, the mouth, or even the skin and genital area. Person-to-person spread is not the usual route; it is mainly an environmental exposure problem. IJORLPMC+1ResearchGateWiley Online Library

Types

1) Nasal/Nasopharyngeal type.
This is the most common type. It involves the inside of the nose or the back of the nose (nasopharynx). It looks like one or more reddish, soft, easily bleeding polyps that can block airflow and cause nosebleeds.

2) Ocular/Conjunctival type.
This type affects the eye’s surface, the inner eyelid, or the tear drainage sac. It can cause a pink, polyp-like mass with irritation, watering, or recurrent, blood-tinged discharge.

3) Oropharyngeal/Laryngeal type.
This type involves the mouth, tonsillar area, or the voice box. It may cause sore throat, difficulty swallowing, voice change, or a sense of a lump.

4) Cutaneous/Subcutaneous type.
This type shows up on the skin or just under the skin as nodules or polyp-like lesions. It may follow autoinoculation (self-spread) from nose or eye lesions through scratching.

5) Genitourinary type.
This type involves the genital or urinary tract mucosa, usually through contaminated water contact, and can present as polyp-like growths that bleed easily.

6) Disseminated type.
In rare cases, lesions appear at many body sites at the same time. This suggests wide local implantation or hematogenous seeding and needs thorough evaluation to map the full extent of disease.

Causes

Note: The single true cause is exposure to Rhinosporidium seeberi. The 20 items below explain environmental risks and personal factors that make exposure and entry more likely.

1) Bathing in village ponds or lakes.
Regular immersion in stagnant or slow-moving fresh water is the strongest risk, because the organism is linked to such waters in endemic regions.

2) Swimming in slow rivers.
Slow rivers can function like ponds. Longer contact time with water increases the chance of mucosal exposure.

3) Washing the face or nose with pond water.
Rinsing the nose with contaminated water can push the organism directly onto injured nasal lining.

4) Occupational exposure to surface water.
Farmers, fishermen, and people who work near ponds and canals may have frequent, repeated contact with contaminated water.

5) Rural residence in endemic regions.
Living in rural areas where pond use is common and sanitation is limited raises cumulative exposure over time.

6) Low socioeconomic status with reliance on natural water.
Limited access to piped or treated water means daily contact with natural water sources.

7) Minor mucosal injuries in the nose or eye.
Small scratches from nose picking, blowing, dust, or contact lenses can create entry points for the organism.

8) Chronic rhinitis or sinusitis.
Ongoing inflammation thins and damages mucosa, making it easier for the organism to implant.

9) Conjunctival irritation.
Irritation from dust, smoke, or allergens makes micro-abrasions more likely, inviting entry when contaminated water splashes the eye.

10) Swimming without eye or nose protection.
Not using goggles or nose clips during freshwater swimming increases the chance of direct inoculation.

11) Cultural or ritual bathing in open water.
Repeated group bathing in the same pond allows ongoing exposure across seasons.

12) Monsoon seasons and flooding.
Monsoon waters can mix soil and organic matter into ponds and create ideal conditions for the organism’s survival.

13) Washing animals or working where animals wade.
Shared human–animal water points can boost environmental contamination.

14) Autoinoculation from existing lesions.
Touching or scratching a nasal or eye lesion, then touching another site, can implant spores elsewhere.

15) Inadequate personal protective habits.
Not washing hands with clean water after pond exposure or after handling pond equipment increases risk of spreading spores to the nose or eyes.

16) Use of unboiled surface water at home.
Using pond or canal water for household tasks, including washing children’s faces, maintains exposure inside the home.

17) Travel to endemic zones with freshwater recreation.
Short trips can be enough if there is close contact with high-risk waters.

18) Crowded living near contaminated ponds.
Homes clustered around a small pond may use it for many activities, increasing frequency of contact.

19) Lack of awareness that the disease is water-linked.
People may not connect red nasal polyps with pond exposure and continue at-risk habits.

20) Immunologic vulnerability or comorbid stressors.
Although not a strict requirement, heavy workloads, malnutrition, or other illnesses can reduce local defenses and assist implantation.

(Items 1–6 and the strong pond association are repeatedly observed in studies from India and Sri Lanka. The “facilitators” explain how exposure leads to inoculation rather than representing alternate causes.) IJORLPMCResearchGate

Symptoms

1) Nasal blockage.
People often notice a stuffed nose on one side or both sides because the soft mass takes up space.

2) Recurrent nosebleeds (epistaxis).
The surface is delicate and full of small blood vessels, so small touches or sneezes can cause bleeding.

3) Red, “strawberry-like” nasal mass.
The mass looks red with tiny white dots (sporangia) on its surface, which is a suggestive appearance for this disease.

4) Watery or mucoid nasal discharge.
The irritated lining produces excess mucus that may drip forward or backward.

5) Sneezing and irritation.
The mass and the inflamed mucosa make the nose more sensitive to air and particles.

6) Snoring or noisy breathing.
Blockage can change airflow and create noise during sleep.

7) Reduced sense of smell.
Airflow that normally carries odors to smell receptors is partly blocked.

8) Foreign body sensation in the throat.
If the mass is in the nasopharynx, people may feel something “stuck” behind the nose.

9) Sore throat or swallowing discomfort.
If the oropharynx is involved, swallowing can rub the lesion and cause pain.

10) Voice change.
When the larynx is affected, hoarseness or a muffled voice can appear.

11) Eye redness and watering.
Ocular lesions irritate the eye surface, so people notice redness, tears, or mild pain.

12) Recurrent blood-tinged eye discharge.
Eye or tear sac lesions can bleed easily, coloring the discharge.

13) Visible pink mass on the eye or lid.
A polyp-like growth on the conjunctiva or near the tear drainage area is sometimes seen.

14) Skin nodules or polyp-like bumps.
Cutaneous lesions feel soft, may bleed with trauma, and are often near previously touched areas.

15) Tiredness from repeated bleeding or poor sleep.
Frequent nosebleeds and blocked breathing at night can cause fatigue and daytime sleepiness.

(The typical “red, polypoidal, bleeding lesion” pattern—especially in the nose or conjunctiva—fits classic descriptions.) Wiley Online LibraryPMC

Diagnostic Tests

Important note: There is no single blood test or routine culture that proves rhinosporidiosis. The definitive diagnosis is made by microscopic examination of tissue showing the characteristic sporangia and endospores, often with special stains. Imaging and functional tests help define the extent and plan care.

A) Physical Exam

1) Exposure-focused history and head-and-neck exam.
The clinician asks about pond or lake exposure, bathing habits, and work around surface water, then inspects the nose, throat, eyes, and skin to look for soft, bleeding lesions and to map how widespread the disease might be. (Pond exposure is a key epidemiologic clue.) IJORL

2) Anterior rhinoscopy.
A light and a nasal speculum are used to see the front part of the nasal cavity. The doctor looks for a red, granular mass with punctate white dots and checks how much of the airway it blocks.

3) Nasal endoscopy (rigid or flexible).
A thin endoscope lets the examiner trace the attachment, base, and extent of the mass deep inside the nose and the nasopharynx, document bleeding points, and plan safe removal.

4) Oropharyngeal and laryngeal inspection.
A mirror or flexible scope checks the tonsillar area, soft palate, and larynx for similar polyp-like lesions if symptoms or spread suggest beyond-nose disease.

5) Comprehensive ophthalmic exam (including lacrimal sac palpation).
If eye symptoms exist, slit-lamp examination and gentle palpation over the tear sac area help find conjunctival or lacrimal sac lesions that match the look and bleeding behavior of nasal lesions.

B) Manual Tests (simple office maneuvers)

6) Cotton-swab “touch-bleed” test.
Very gentle contact with a cotton swab may provoke pinpoint bleeding from the fragile lesion surface, supporting the impression of a vascular, friable mass typical of this condition.

7) Cold-mirror fogging (nasal airflow patency).
A cool metal or glass mirror placed under the nostrils fogs with exhaled air; unequal fogging suggests blockage on one side and helps track response after treatment.

8) Valsalva or phonation observation.
Asking the patient to perform a light Valsalva or speak vowel sounds can reveal movement of a pedunculated mass or show how the lesion changes airflow and resonance.

C) Lab and Pathological Tests (the core of diagnosis)

9) Imprint cytology (MGG or Pap stain) from the lesion.
A fresh surface imprint or smear can show round sporangial structures and endospores on simple stains like May-Grünwald-Giemsa, providing a quick, inexpensive clue while waiting for histology. PMC

10) Fine-needle aspiration cytology (FNAC) for skin/subcutaneous lesions.
When a cutaneous or subcutaneous nodule is present, FNAC may retrieve characteristic sporangial elements, guiding early suspicion before excision.

11) Excisional or incisional biopsy with H&E histology (definitive).
This is the gold standard. On routine hematoxylin and eosin staining, pathologists see thick-walled sporangia at different stages, filled with numerous endospores, in a background of inflamed tissue. This signature picture confirms rhinosporidiosis. PMCResearchGate

12) Periodic acid–Schiff (PAS) special stain.
PAS highlights polysaccharide-rich walls of the sporangia and helps bring out small structures, making recognition easier in difficult or small biopsies. PMC

13) Gomori methenamine silver (GMS) special stain.
GMS can outline the sporangial wall and endospores in black against a pale background, adding contrast and confidence to the diagnosis in tricky cases. PMC

14) Molecular detection (PCR/sequencing of 18S rRNA gene).
Where available, labs amplify small-subunit ribosomal RNA gene fragments unique to R. seeberi. This can confirm identity when morphology is atypical or the sample is scant. ASM Journals

15) Bacterial swab and culture for superinfection (organism itself does not culture).
The causative organism has not been reliably grown in routine culture; however, surface swabs may grow bacteria from secondary infection that need treatment. This “negative culture for R. seeberi but positive histology” pattern is typical. ScienceDirect

D) Electrodiagnostic / Functional Tests

There is no disease-specific electrodiagnostic test for rhinosporidiosis. In selected patients, a functional airflow study is useful:

16) Rhinomanometry (computer-assisted nasal airflow/resistance).
This test measures nasal airflow and resistance during quiet breathing. It does not diagnose the organism, but it quantifies how much the mass blocks airflow and helps document improvement after therapy.

E) Imaging Tests

17) CT scan of paranasal sinuses and nasopharynx.
CT shows where the lesion sits, how broad the attachment is, whether there is expansion into adjacent spaces, and whether sinuses are secondarily involved. It guides surgical planning and cautery strategy to reduce bleeding risk.

18) MRI of face and orbit (with contrast).
MRI better shows soft-tissue planes, orbital extension, and nasopharyngeal or skull-base proximity. It helps when ocular or deep extension is suspected from symptoms.

19) Ultrasonography for lacrimal sac and superficial masses.
High-resolution ultrasound is quick and noninvasive for tear-sac lesions or superficial nodules, showing a vascular soft-tissue mass and helping pick safe biopsy sites.

20) Dacryocystography or dacryoscintigraphy (if lacrimal sac involved).
Contrast studies of the tear drainage system map filling defects and block points, helping plan definitive removal when the tear sac is affected.

Non-pharmacological treatments (therapies & others)

Each item includes a short description, purpose, and mechanism in simple terms.

1. Endoscopic surgical excision with base cauterization — The surgeon uses a thin camera through the nostril to remove the mass and then burns (cauterizes) the base. Purpose: remove all infected tissue and kill any leftover spores. Mechanism: physical removal + heat to destroy sporangia and reduce re-implantation. This is the standard of care. Turkish Archives

2. Wide local excision for external or oral lesions — For skin, oral cavity, or genital lesions, the mass is cut out with a small safety margin. Purpose: clear disease where endoscopy isn’t practical. Mechanism: complete removal of infected tissue. Jomos

3. Laser-assisted excision (CO₂/Diode/KTP) — A surgical laser cuts and seals at the same time. Purpose: better visibility, less bleeding, and cleaner margins to lower recurrence. Mechanism: precise vaporization of tissue and thermal kill of spores at the base. PubMedPMC+1

4. Coblation-assisted excision — Radiofrequency energy in a saline field “cold-ablates” tissue. Purpose: reduce heat spread and aerosolization. Mechanism: ionized saline disrupts tissue at lower temperatures, aiming to minimize spore dissemination. PMCTurkish Archives

5. Electrocautery of the attachment site — After removal, the base is electrocauterized. Purpose: kill any remaining spores. Mechanism: heat coagulates proteins and destroys sporangia. Turkish Archives

6. Cryopexy / cryocautery (selected cases) — Targeted freezing of the base. Purpose: another way to destroy residual organisms. Mechanism: ice crystal damage causes cell death in residual tissue. (Used by some specialists; evidence limited.) Hopkins Guides

7. Bronchoscopic or tracheal removal for airway lesions — When the airway is involved, a scope is used to shave or excise growths. Purpose: restore airflow and prevent bleeding or obstruction. Mechanism: endoscopic debulking with tools such as a microdebrider. PMC

8. Dacryocystectomy for lacrimal sac disease — Surgical removal of diseased lacrimal sac when the tear drainage system is involved. Purpose: cure local disease and stop tearing/recurrence. Mechanism: complete excision of infected mucosa. OAEPublish

9. Intra-operative meticulous suction and field control — Use of suction and hemostasis throughout. Purpose: limit spore spread and improve visibility. Mechanism: reduces contamination of nearby tissue. PMC

10. Saline nasal care after surgery — Gentle saline sprays/rinses once the surgeon allows. Purpose: keep the nose clean and support healing. Mechanism: mechanical clearance of crusts without trauma. (Supportive care; not curative by itself.) PMC

11. Avoidance of pond/river bathing during healing — Keep away from likely sources during recovery. Purpose: prevent re-exposure. Mechanism: removes environmental risk. PMCLippincott Journals

12. Bleeding control measures (nasal packing if needed) — Temporary packing for brisk bleeds. Purpose: stop epistaxis safely. Mechanism: pressure/tamponade. PMC

15. Community water hygiene / alternative bathing — Use safe water sources. Purpose: reduce community burden. Mechanism: less exposure to contaminated stagnant water. Lippincott Journals

16. Protective practices for sand/river workers — PPE and minimizing mucosal trauma. Purpose: reduce occupational exposure. Mechanism: barrier protection and behavior change. IJORL

17. Laser spot-cautery of satellite lesions — Treat tiny nearby implants during surgery. Purpose: reduce recurrence. Mechanism: immediate ablation of micro-lesions. Oxford Academic

18. Careful specimen handling — Contain tissue and avoid spillage. Purpose: prevent operating-room contamination and autoinoculation. Mechanism: closed suction and bagging of tissue. PMC

19. Oral cavity and skin wound care — For extra-nasal sites, gentle hygiene and protection. Purpose: support healing, reduce secondary infection. Mechanism: clean, moist wound care principles. Jomos

20. Multidisciplinary planning in disseminated disease — ENT, dermatology, ophthalmology, thoracic, and ID teams. Purpose: coordinate staged surgeries and adjuncts. Mechanism: site-specific combined care lowers complications. Turkish Archives

Drug treatments

Key safety note: There is no proven curative medicine for rhinosporidiosis. Surgery is primary. Medicines below are used as adjuncts or in special situations (e.g., disseminated disease) under specialist care; evidence quality ranges from modest to very limited. Do not self-medicate. Hopkins Guides+1

1. Dapsone (sulfone class) — Typical specialist practice: 50–100 mg by mouth daily for months (often 6–12 months) after surgery in recurrent or disseminated cases, individualized to labs and tolerance. Purpose: lower risk of recurrence and help shrink residual microscopic disease. Mechanism: interferes with maturation of sporangia and promotes fibrosis in the stroma. Side effects: hemolytic anemia (especially in G6PD deficiency), methemoglobinemia, rash/DRESS, neuropathy; requires CBC, methemoglobin risk counseling, and often G6PD screening first. PMCJuniper PublishersNCBI

2. Ketoconazole (azole antifungal; off-label/limited data) — Use: sometimes tried in disseminated disease when surgery is incomplete. Timing: long courses under supervision. Purpose/Mechanism: ergosterol synthesis inhibition; theoretical activity. Side effects: hepatotoxicity, drug interactions; uncertain benefit. Hopkins Guides

3. Itraconazole (azole; off-label/very limited evidence) — Use: occasional case-based use. Purpose/Mechanism: azole antifungal activity; unclear clinical efficacy in this organism. Side effects: liver toxicity, interactions; not routine. E-MJM

4. Amphotericin B (polyene; off-label/limited evidence) — Use: has been tried when disease is severe or disseminated and surgery is incomplete. Mechanism: binds ergosterol-like targets; benefit uncertain. Side effects: nephrotoxicity, electrolyte issues. PubMed

5. Ciprofloxacin (fluoroquinolone; anecdotal reports) — Use: reported historically; not recommended routinely due to insufficient data. Side effects: tendinopathy, QT effects, interactions. Hopkins Guides

6. Cycloserine (antimycobacterial; salvage in combos) — Use: part of combination regimens in disseminated disease in rare reports, often alongside dapsone ± azole. Side effects: neurotoxicity; used only with expert oversight. Evidence: mixed, sometimes ineffective. PMCSpringerLink

7. Posaconazole (azole; theoretical/very sparse) — Use: azole with broad antifungal spectrum; no robust rhinosporidiosis data—mentioned here only because it’s occasionally discussed in refractory mucosal mycoses; not standard. Side effects: liver, interactions. PubMed

8. Topical biocides during surgery (e.g., povidone-iodine) — Use: antiseptic irrigation of the bed is sometimes employed intra-operatively. Mechanism: broad antimicrobial action; lab work has explored effects on endospores, but clinical impact is uncertain. Side effects: mucosal irritation if overused. PubMed

9. Analgesics and hemostatic agents (supportive) — Use: pain control and bleeding control after surgery. Mechanism: symptomatic support; do not treat the organism. Side effects: class-specific; use as directed by surgeon. PMC

10. Antibiotics for secondary bacterial infection only — Use: if the surgical site gets secondarily infected. Mechanism: treat bacteria, not Rhinosporidium. Side effects: class-specific; short courses only when indicated. PMC

Dietary “molecular” supplements

Important: No supplement cures rhinosporidiosis. These are general recovery-support ideas (wound healing, immune health) to discuss with your clinician, especially if taking dapsone (due to anemia/methemoglobinemia risks). Hopkins Guides

1. Vitamin C (e.g., 250–500 mg/day) — Supports collagen and wound healing; antioxidant support.

2. Vitamin A (dietary or short-term supplement if deficient) — Supports mucosal lining repair and immune function.

3. Vitamin D (per blood level; often 800–2000 IU/day if low) — Broad immune modulation; deficiency is common.

4. Zinc (10–20 mg elemental/day short term) — Aids epithelial repair and immune enzymes.

5. Selenium (50–100 µg/day) — Antioxidant cofactor supporting glutathione peroxidase.

6. Omega-3 fatty acids (fish oil providing ~1 g/day EPA+DHA) — Anti-inflammatory support during healing.

7. Probiotics (standard daily dose) — Gut-immune axis support if on peri-operative antibiotics.

8. Curcumin (turmeric extract, 500–1000 mg/day with food) — Anti-inflammatory/antioxidant; check interactions.

9. Quercetin (250–500 mg/day) — Antioxidant; potential mast-cell stabilizing effects.

10. N-acetylcysteine (600 mg once or twice daily) — Antioxidant precursor to glutathione; avoid if advised by your clinician due to interactions.

(These are general, not disease-specific; prioritize a whole-food diet first, and clear every supplement with your doctor if you’re on dapsone.) NCBI

Regenerative / stem cell” drugs

There are no approved regenerative or stem-cell drugs for rhinosporidiosis, and using them for this disease is not recommended. What helps most is complete surgical removal plus careful cauterization, with dapsone sometimes added to reduce recurrence risk. If someone suggests immune-boosting injections or stem-cell therapies for this condition, ask for clinical-trial evidence and safety data—currently there isn’t reliable support. Safe, evidence-based care focuses on surgery, hygiene, and targeted follow-up. Turkish ArchivesHopkins Guides

Surgeries

1. Endoscopic nasal excision with base cauterization — Standard primary treatment for nasal/nasopharyngeal disease. Why: reliably removes the mass and lowers recurrence by destroying residual spores. Turkish Archives

2. Laser-assisted endoscopic resection (CO₂/diode/KTP) — Used in primary or recurrent disease to minimize bleeding and improve margin control. Why: better visualization and thermal sterilization of the base. PubMed

3. Coblation-assisted resection — Radiofrequency “cold ablation” tool. Why: less lateral thermal damage and spore scatter; helpful in recurrences. PMC

4. Dacryocystectomy (tear sac excision) for lacrimal disease — Why: complete clearance when the tear drainage system is infected, preventing persistent tearing and relapse. OAEPublish

5. Bronchoscopic removal/microdebridement for airway lesions — Why: relieve obstruction, control bleeding, and obtain diagnosis in rare tracheobronchial disease. PMC

When to see a doctor (red flags)

• Any new bleeding nasal/ocular/oral mass, especially if it bleeds on touch or blocks breathing.

• Recurrent nosebleeds, nasal blockage, or a “strawberry-like” polyp that keeps growing.

• Eye symptoms such as a reddish mass on the conjunctiva or persistent tearing/swelling near the inner corner of the eye. PMC

• Breathing trouble, cough, or bleeding from the airway if you’ve had disease in the nose or had surgery. PMC

• After surgery: increasing pain, foul discharge, fever, or rapid regrowth at the site. PMC

• If prescribed dapsone: dark urine, shortness of breath, bluish lips, unusual fatigue, or jaundice—these can signal hemolysis or methemoglobinemia and need urgent care. NCBIACP Hospitalist

Foods to favor and to limit

What to eat (helps healing and immunity):

1. Lean proteins (fish, eggs, legumes) to rebuild tissues.

2. Citrus and guava for vitamin C to support wound repair.

3. Orange-yellow vegetables (carrots, pumpkin) for vitamin A and mucosal health.

4. Nuts, seeds, whole grains for zinc and selenium.

5. Yogurt/fermented foods for probiotics.

6. Fatty fish (hilsa, sardine) for omega-3s.

7. Leafy greens for folate and minerals.

8. Plenty of clean water (safe source) to keep secretions thin.

9. Turmeric/ginger in cooking for anti-inflammatory spice support.

10. Iron-rich foods (if your clinician says you’re anemic). (Coordinate with labs if on dapsone.) NCBI

What to limit/avoid:

1. Unhygienic/stagnant water exposure (not a food, but crucial). Lippincott Journals

2. Ultra-processed sugary snacks that inflame and slow healing.

3. Excess alcohol, which impairs immunity and interacts with many medicines.

4. Very spicy/hot foods if they trigger nose irritation soon after surgery.

5. Smoking/tobacco (irritates mucosa, impairs healing).

6. If G6PD-deficient and on dapsone: avoid oxidative triggers (your clinician will counsel you). NCBI

7. Herbal products that thin blood right before/after surgery unless cleared by your surgeon.

8. High-dose vitamin/mineral “stacks” without medical advice—interactions happen.

9. Raw or undercooked street foods while healing (infection risk).

10. Unverified “immune booster” injections or stem-cell products marketed online—no evidence for this disease. Hopkins Guides

FAQs

1) Is rhinosporidiosis contagious from person to person?
No. It’s linked to environmental exposure, especially to stagnant pond/river water in endemic regions, not to casual human-to-human spread. PMC

2) Why do the growths look like strawberries?
Because the organism forms round sacs (sporangia) that push up under the surface, creating tiny white dots on a red polyp. PubMed

3) What is the best treatment?
Surgical removal of the lesion plus cauterization of the base is the mainstay. Medicines have limited roles. Turkish Archives

4) Will it come back after surgery?
It can. Careful base cautery and modern tools (laser/coblation) aim to reduce this risk, and some doctors add dapsone when recurrences are a problem. PubMedPMC

5) What is dapsone and why is it used?
It’s a sulfone antibiotic with unique effects on this organism’s life cycle. It may help reduce recurrences after surgery, but it’s not a stand-alone cure and needs blood test monitoring. PMC

6) Is there a pill that cures rhinosporidiosis?
No proven pill. Reports exist for azoles, amphotericin, ciprofloxacin, and others, but evidence is weak and inconsistent. Surgery remains primary. Hopkins Guides

7) How is it diagnosed?
By biopsy and histopathology showing sporangia and endospores; imaging/endoscopy help define the extent. Am J Trop Med Hyg

8) Where on the body can it occur?
Most often nose/nasopharynx; it can affect the eye (conjunctiva/lacrimal sac), oral cavity, skin, genital/urinary sites, and rarely the airway/lungs. PMC

9) Why does stagnant water matter?
The organism is water-associated; exposure during pond/river bathing is a consistent risk factor in endemic areas. PMC

10) Are lasers better than regular surgery?
Lasers can reduce bleeding and may help reduce recurrence in experienced hands, but availability and skill matter more than the tool. PubMed

11) What about coblation?
Coblation is another tool that can precisely remove tissue at lower temperatures; some centers report good results in recurrent disease. PMC

12) Can children get rhinosporidiosis?
Yes, although adults in certain occupations are frequently affected; management principles are similar. PubMed

13) How long do I need follow-up?
Your surgeon will usually monitor for months to years because late recurrences can occur, especially if exposure continues. Turkish Archives

14) I’m on dapsone—what tests do I need?
Doctors commonly check G6PD status, complete blood counts, and watch for signs of methemoglobinemia or hemolysis. Report shortness of breath, blue lips, dark urine, or unusual fatigue immediately. NCBIACP Hospitalist

15) What’s the single most important thing I can do to prevent it?
Avoid bathing in stagnant, possibly contaminated surface water and follow your surgeon’s aftercare instructions. Lippincott Journals
