Cicatricial Pemphigoid

Cicatricial pemphigoid is an autoimmune disease. “Autoimmune” means your immune system attacks your own body by mistake. In this disease, the attack happens at the basement membrane. This is the thin glue-like layer that anchors the surface lining (the epithelium) to the tissue under it. When the body attacks this layer, blisters form on moist linings called mucous membranes. These linings are inside the mouth, eyes, nose, throat, food pipe, windpipe, and the genital and anal areas. The blisters break and leave painful raw areas. As the raw areas heal, they can make scar tissue. Scar tissue can change how tissues move, open, and close. This is why the word “cicatricial” (scarring) is used.

The eyes are very important here. Eye involvement can lead to sticky bands between the eyelid and the eye (symblepharon), inward turning of the lashes (trichiasis), dry eye, infections, and even vision loss over time. The mouth is commonly involved. People get fragile blisters that burst into red, sore ulcers. The throat and voice box can also scar. This can cause hoarse voice, choking, or trouble breathing in severe cases. The skin may be normal or only mildly affected. Compared with bullous pemphigoid (another blistering disease), cicatricial pemphigoid prefers mucous membranes and tends to scar.

Doctors think several target proteins can be attacked by the immune system in this disease. These include parts of BP180 (type XVII collagen), laminin-332 (also called epiligrin or nicein), BP230, and type VII collagen. Which protein is targeted can affect how the disease behaves. For example, antibodies to laminin-332 may be linked with a higher chance of an internal cancer being found in some patients. Not every patient has detectable blood antibodies. A special biopsy test with direct immunofluorescence is the most important test to prove the diagnosis.

Cicatricial pemphigoid is long-term (chronic). It often comes and goes. Early diagnosis and treatment help prevent scarring and serious problems, especially in the eyes and airway. Treatment plans depend on where the disease is active and how severe it is. Eye or airway disease is urgent because scarring there can be permanent.

Other names

• Mucous membrane pemphigoid (MMP) – the umbrella term most experts use today

• Ocular cicatricial pemphigoid (OCP) – when the eyes are the main site

• Cicatricial (scarring) MMP – highlights the scarring nature

• Anti-epiligrin/anti-laminin-332 MMP – when antibodies target laminin-332

• Oral pemphigoid – when mainly the mouth is involved

Types

1. By main body site

   • Ocular-predominant: the eyes are the main problem; scarring risk is high.

   • Oral-predominant: mostly mouth sores; scarring may cause gum recession and tight mouth opening.

   • Laryngopharyngeal/airway-predominant: voice, swallowing, or breathing problems due to scarring.

   • Anogenital-predominant: painful sores and scarring, sexual or toileting discomfort.

   • Multifocal: two or more mucosal sites are active.

   • Cutaneous-limited scarring (less common): skin with scarring but little mucosal disease.

2. By target antigen (lab pattern)

   • Anti-BP180/BP230 MMP: shares targets with bullous pemphigoid but involves mucosa and scars.

   • Anti-laminin-332 (epiligrin) MMP: sometimes linked with hidden cancers; doctors may screen.

   • Anti-type VII collagen MMP: overlaps with forms of epidermolysis bullosa acquisita.

   • Seronegative MMP: biopsy proves disease but blood antibody tests are negative.

3. By severity

   • Low-risk: only mouth involvement without scarring risk.

   • High-risk: eyes, airway, or widespread mucosa where scarring can cause disability or vision loss.

Causes

Note: “Cause” here means a factor linked to triggering or shaping the autoimmune attack. In many people no single trigger is found.

1. Autoimmunity itself. The core driver is a mistaken immune attack on the basement membrane zone. Antibodies line up along this zone and start inflammation that splits the lining from the tissue beneath. DermNet®

2. Targeting BP180 (collagen XVII). Antibodies against deeper parts of BP180 can produce scarring disease rather than the more superficial blisters seen in classic bullous pemphigoid. NCBI

3. Targeting laminin-332. Antibodies to this protein are a well-defined MMP subtype and are important because of a reported link to solid cancers in a subset of patients. PMC

4. Targeting integrin α6β4. This hemidesmosome receptor helps anchor epithelial cells; antibodies to it are found in some patients, especially with eye disease. NCBI

5. Targeting BP230. Some patients show antibodies to this structural protein; on its own it is not specific, so doctors interpret it with other tests. JAMA Network

6. Targeting type VII collagen. Rarely, the autoimmune focus is on this anchoring-fibril collagen. Clinically it can resemble other blistering diseases. DermNet®

7. Genetic predisposition (HLA-DQB1*0301). This HLA class II allele is repeatedly associated with MMP and may make people more likely to form basement-membrane antibodies. PubMed

8. Ageing immune system. The disease mostly affects older adults; age-related immune shifts likely help unmask autoimmunity. DermNet®

9. Female sex predominance. Women are affected more often than men, suggesting hormonal or immune-regulatory influences. DermNet®

10. Local tissue injury (Koebner-like effect). Dental procedures, eye surgery, or trauma can sometimes localize or unmask disease at that site by exposing basement-membrane antigens. (Clinical observation discussed across reviews.) NCBI

11. Chronic gum inflammation. Periodontal disease may make oral tissues fragile and inflamed, lowering the threshold for blistering. NCBI

12. Dry-eye disease and ocular surface irritation. Ongoing surface inflammation in the eye can worsen scarring in ocular disease. Spandidos Publications

13. Medications—penicillamine. Rare “drug-associated” pemphigoid-type reactions are reported with penicillamine and a few other drugs; some cases show mucosal involvement. PMC

14. Medications—loop diuretics and penicillins. Strong evidence links these drugs to bullous pemphigoid broadly; mucosal-predominant cases are described but are uncommon. Medical Journals Sweden

15. Medications—immune checkpoint inhibitors (PD-1/PD-L1). These cancer drugs can trigger pemphigoid diseases, sometimes with mouth and eye lesions. PMC

16. Infections as immune triggers. Infections may “prime” the immune system and expose basement-membrane antigens, setting off disease in susceptible people. (General mechanism noted in pemphigoid reviews.) SpringerLink

17. Smoking or environmental irritants. Irritants that inflame mucosa (especially eyes) may aggravate symptoms and scarring. (Ocular surface reviews discuss risk factors for worsening.) Spandidos Publications

18. Cancer in laminin-332–positive patients. In this specific subtype, anti-laminin-332 antibodies and an underlying solid tumor sometimes occur together, suggesting a paraneoplastic link in a subset. PMC+1

19. Immune dysregulation after surgery or radiation. Tissue remodeling can expose antigens and alter immune responses, occasionally unmasking disease. (Discussed in narrative reviews.) SpringerLink

20. Idiopathic (no clear trigger). In many patients, no single trigger is found; the disease is simply autoimmune by nature. DermNet®

Symptoms

1. Mouth soreness and burning. The gums, cheeks, or palate feel sore. Eating spicy, acidic, or rough foods hurts. Raw areas bleed easily. DermNet®

2. Desquamative gingivitis. The gum surface peels and looks red and shiny around teeth; brushing may cause bleeding. DermNet®

3. Blisters or ulcers in the mouth. Blisters break quickly, so you mostly see shallow, painful erosions. They heal slowly and can scar. DermNet®

4. Eye redness, tearing, stinging, or burning. Often starts like chronic conjunctivitis that does not go away. American Academy of Ophthalmology

5. Dry eyes and gritty feeling. Tear production drops. People describe sand in the eye. PMC

6. Light sensitivity and blurred vision. Surface damage and scarring can make vision fluctuating or blurry. Spandidos Publications

7. Lashes rubbing the cornea (entropion/trichiasis). Scarring turns the lid inward so lashes scratch the eye. This raises the risk of corneal injury. DermNet®

8. Bridging scars (symblepharon). The inner eyelid sticks to the eyeball. Fornices shorten, and the eye feels tight. DermNet®

9. Nose symptoms. Crusting, nosebleeds, and soreness. DermNet®

10. Hoarseness or noisy breathing. Scarring of the voice box or windpipe can cause a rough voice or stridor; this needs urgent assessment. DermNet®

11. Trouble swallowing. Esophageal involvement causes pain on swallowing and food sticking. Long-standing disease can cause strictures. DermNet®

12. Genital soreness and pain. Erosions can cause pain with urination or sex, and scarring can narrow openings. DermNet®

13. Skin blisters that scar. Less common than mucosal disease; when present, skin blisters on the head/neck may heal with scars. DermNet®

14. Tooth problems over time. Chronic gum disease and pain can lead to cavities and tooth loss if not managed. NCBI

15. Anxiety and reduced quality of life. Long-lasting pain, eye symptoms, and eating limits can affect mood, sleep, and daily life. BioMed Central

Diagnostic tests

Important: No single test fits everyone. Doctors combine a careful exam with targeted tests. The key test is direct immunofluorescence (DIF) on a small biopsy from a mucosal site. If it is negative but suspicion is high, doctors may biopsy a second site or skin to increase the chance of a positive result. JAMA Network

A) Physical examination (bedside and clinic exams)

1. Full mucosal map. The doctor looks carefully at the mouth, eyes, nose, throat, genitals, and perianal skin to list all involved sites. This guides both treatment and biopsy site choice. DermNet®

2. Oral exam for desquamative gingivitis. Gentle probing of the gums shows easy peeling, redness, and bleeding; this pattern suggests an autoimmune blistering disease. DermNet®

3. Slit-lamp eye exam with dye. Fluorescein and lissamine green highlight surface damage. The examiner everts lids to look for early symblepharon and lid changes. Wills Eye Hospital

4. Eyelid eversion and fornix depth check. Measuring how deep the lower fornix is helps track scarring over time and plan treatment. BioMed Central

5. ENT airway exam. If there is hoarseness, stridor, or swallowing problems, an ENT specialist inspects the nose, pharynx, larynx, and sometimes the esophagus to detect scarring or narrowing early. DermNet®

B) Manual/office tests (simple functional tests)

6. Schirmer tear test. A tiny strip of paper under the lower lid measures tear production in 5 minutes; low numbers are common in ocular disease. PMC

7. Tear film break-up time (TBUT). A drop of fluorescein helps measure how fast the tear film breaks up; fast break-up suggests a dry, inflamed surface. Spandidos Publications

8. Ocular surface staining scores. Lissamine green and fluorescein staining grades help track improvement or worsening with therapy. American Academy of Ophthalmology

9. Oral pain and function check. Simple measures—what foods are painful, how long brushing takes, and bleeding with brushing—help score severity and track response. (Clinical practice standards.) DermNet®

10. Swallowing and voice assessment. Bedside swallowing checks and voice quality ratings prompt instrumental testing if there are red flags. DermNet®

C) Laboratory & pathological tests (definitive tests)

11. Direct immunofluorescence (DIF) on mucosal biopsy. This is the cornerstone test. A small perilesional or even normal-appearing mucosal biopsy often shows a linear band of IgG, IgA, and/or C3 along the basement membrane. If the first biopsy is negative but suspicion is high, doctors take another from a different site or from skin to raise the yield. JAMA Network

12. DIF on skin (backup site). In some patients with negative mucosal DIF, a skin biopsy is positive and clinches the diagnosis. JAMA Network

13. Indirect immunofluorescence (IIF) on salt-split skin. This blood test looks for circulating antibodies and shows whether they bind to the “epidermal” or “dermal” side of an artificial split. It is very specific but less sensitive than DIF in MMP, so a negative result does not rule out disease. JAMA Network

14. ELISA panels (BP180, BP230). These tests detect antibodies against common targets. They help—but can miss MMP because some patients have low or different targets. Results are interpreted with clinical and DIF findings. JAMA Network

15. Special assays for laminin-332 and α6β4 integrin. Immunoblotting, biochip, or “keratinocyte footprint” assays can identify these subtypes when standard ELISAs are negative. Flagging laminin-332 is important because it may trigger cancer screening. Groningen Research Portal

16. Routine blood work (baseline and safety). Doctors check blood counts, kidney/liver tests, and nutrition; these help plan safe treatment and track health. (General practice; supportive not diagnostic.)

17. Microbiology when needed. If there is heavy crusting or infection, swabs can guide antibiotics; this is supportive care rather than diagnosis.

D) Electrodiagnostic tests (rarely used in MMP)

18. Note on electrodiagnostics. There is no standard electrodiagnostic test for MMP itself. Tests like visual evoked potentials or electrooculography are reserved for unusual cases when doctors suspect another eye disease affecting the retina or optic nerve. They are not part of routine MMP work-ups. (Consensus across ophthalmology reviews.) Spandidos Publications

E) Imaging and instrumented tests

19. Anterior-segment optical coherence tomography (AS-OCT). This painless imaging scan shows conjunctival scarring, fornix shortening, and corneal surface changes, and helps monitor disease. PMC+1

20. In vivo confocal microscopy (IVCM). This high-resolution microscope images the eye surface at the cellular level. It can demonstrate inflammatory and scarring changes and follow response to treatment. PMC

21. Upper endoscopy or barium swallow. These tests look for esophageal erosions or strictures when swallowing is painful or difficult. They help plan dilation or other care. (GI practice standards referenced in MMP reviews.) DermNet®

22. ENT laryngoscopy. A flexible scope checks the larynx and trachea if there is hoarseness or noisy breathing, to catch scarring that could threaten the airway. DermNet®

23. Cancer screening in laminin-332–positive MMP. Because anti-laminin-332 MMP can be linked to solid cancers in a subset, doctors consider age-appropriate imaging and cancer screening soon after diagnosis and during the first year, guided by symptoms and exam. PMC+1

Non-Pharmacological Treatments

1) Eye lubrication & protection
Description: Frequent preservative-free artificial tears and nighttime ointments keep the eye’s surface wet, reduce friction from blinking, and protect healing tissue. Moisture chamber glasses or wraparound eyewear guard against wind and dust. For eyelid inflammation, warm compresses and gentle lid hygiene lower bacterial load and oil gland clogging. In early disease, good lubrication can shorten the time sores stay open, reduce pain, and lower the chance of eyelid sticking to the white of the eye. Because scarring tends to start in the corners of the eyes, consistent lubrication helps keep tissues sliding smoothly. Patients with screen time or air-conditioned offices usually need drops more often. Regular use can also cut down on the need for strong steroid drops and help stabilize vision.
Purpose: Reduce dryness, pain, friction, and scar risk.
Mechanism: Forms a protective film, reduces mechanical micro-trauma, supports epithelial repair.

2) Dental and oral wound care program
Description: A soft-bristle toothbrush, non-foaming toothpaste (SLS-free), alcohol-free mouthwash, and daily salt-bicarbonate rinses lower irritation in fragile mouth lining. A dental hygienist trained in oral mucosal disease can adjust cleaning techniques, avoid sharp tools on active erosions, and schedule shorter, gentler sessions. Custom trays can apply bland emollients or topical meds evenly. Avoid spicy, acidic, and very hot foods during flares. This plan shortens healing time and reduces bleeding.
Purpose: Keep the mouth clean and comfortable while ulcers heal.
Mechanism: Minimizes chemical and mechanical irritants; supports mucosal barrier function.

3) Soft diet and swallowing strategies
Description: During throat or esophageal involvement, choose soft, moist foods (soups, yogurt, mashed foods) and add sauces to keep bites slippery. Take small bites, chew well, and sip water between bites. A speech-language pathologist can coach safe swallowing positions if pain or narrowing exists.
Purpose: Reduce trauma and pain with eating.
Mechanism: Lowers friction across ulcers; prevents micro-tears that trigger extra inflammation.

4) Humidification & gentle airway care
Description: Room humidifiers and steam inhalation (as tolerated) ease dryness in nose and throat. Saline sprays soften crusts. Avoid forceful nose blowing. If the voice box is inflamed, voice rest and hydration protect the vocal folds.
Purpose: Protect nose/throat mucosa and voice.
Mechanism: Raises local moisture and reduces shear stress on fragile tissue.

5) Protective lifestyle adjustments
Description: Avoid tobacco, very hot drinks, strong spices, and abrasive foods (chips, crusts). Limit alcohol mouthwashes. Use sun protection on lip lesions. Manage reflux (smaller meals, head-of-bed elevation) to reduce acid contact with ulcers.
Purpose: Reduce triggers that worsen erosions.
Mechanism: Cuts chemical/thermal irritation and secondary inflammation.

6) Lid hygiene & meibomian gland care
Description: For ocular disease, gentle daily lid warming and massage improve oil flow, stabilizing the tear film and reducing dry-eye friction.
Purpose: Stabilize tear film and comfort.
Mechanism: Improves lipid layer quality; less evaporation.

7) Physical and occupational therapy for mouth opening & scarring
Description: Gentle jaw stretching, prescribed by specialists, helps maintain mouth opening if scarring tightens oral tissues. Custom devices or exercises can prevent trismus.
Purpose: Preserve function for eating, dental care, and speech.
Mechanism: Slow, regular stretching counteracts contracture formation.

8) Wound-healing hygiene (body/genital mucosa)
Description: Lukewarm bathing, pH-balanced cleansers, and bland emollients protect surrounding skin. Use breathable, non-friction clothing. For genital erosions, sitz baths and barrier creams reduce pain and maceration.
Purpose: Speed epithelial repair and reduce infections.
Mechanism: Moist wound care; barrier support minimizes shear and contamination.

9) Psychological support & pain coping
Description: Chronic pain, feeding difficulty, and vision anxiety increase stress. Brief cognitive-behavioral strategies, support groups, and relaxation training reduce pain perception and improve adherence to care.
Purpose: Improve quality of life and resilience.
Mechanism: Reduces central sensitization and stress-driven flares.

10) Infection prevention education
Description: Teach early signs of secondary infection (increasing pain, pus, fever), safe mouth care, and when to seek help. Vaccinations per clinician guidance (e.g., influenza, pneumococcal) may be recommended.
Purpose: Catch infections early; avoid complications.
Mechanism: Prompt response reduces microbial load and systemic spread.

11) Multidisciplinary monitoring (derm, ophthal, ENT, oral med)
Description: Coordinated visits spot early scarring in eyes, airway, and esophagus—areas where delay can cause permanent harm.
Purpose: Detect progression early.
Mechanism: Regular, targeted exams guide timely escalation.

12) Nutritional support
Description: If weight loss occurs, a dietitian can add calorie-dense, soft options and ensure adequate protein, zinc, and vitamins to aid healing.
Purpose: Prevent malnutrition and support tissue repair.
Mechanism: Provides building blocks for mucosal regeneration.

13) Reflux control measures
Description: Avoid late meals, elevate head of bed, and consider clinician-guided antireflux strategies to reduce acid injury to mouth/throat sores.
Purpose: Protect erosions from acid contact.
Mechanism: Less acid exposure = better healing.

14) Avoid trauma during dental/medical procedures
Description: Alert providers that mucosa is fragile; request gentle instruments, lubrication, and protective barriers.
Purpose: Prevent new erosions.
Mechanism: Minimizes mechanical shear.

15) Saliva support (xerostomia care)
Description: Sugar-free lozenges, xylitol gum, and saliva substitutes ease dry mouth symptoms and reduce cavity risk.
Purpose: Comfort and oral health.
Mechanism: Boosts saliva or replaces it to protect mucosa and teeth.

16) Protective eye taping at night (select cases)
Description: If incomplete eyelid closure, soft taping or shields prevent exposure keratopathy.
Purpose: Shield cornea.
Mechanism: Maintains ocular surface moisture.

17) Gentle nasal care
Description: Saline gels and humidification limit crusting and bleeding.
Purpose: Comfort and healing.
Mechanism: Hydrates mucosa; lowers friction.

18) Voice conservation strategies
Description: Microphone use, scheduled voice breaks, and hydration lower strain during laryngeal involvement.
Purpose: Reduce injury to vocal folds.
Mechanism: Less mechanical stress and dryness.

19) Safe skincare around lesions
Description: Fragrance-free, hypoallergenic products prevent contact dermatitis that could worsen disease.
Purpose: Reduce irritant/allergic triggers.
Mechanism: Minimizes barrier disruption.

20) Patient-held care plan & photo tracking
Description: Simple checklists and monthly photos help track changes and prompt timely review.
Purpose: Empower self-monitoring.
Mechanism: Early pattern recognition and adherence support.

Drug Treatments

1) Systemic corticosteroids (prednisone/prednisolone)
Description: Oral steroids are often used to quickly calm severe inflammation, especially with eye, throat, or esophageal risk. They reduce immune activity broadly, shrinking blisters and pain within days. Because long-term steroids cause side effects (weight gain, mood changes, high blood sugar, blood pressure rise, bone loss, infection risk), clinicians usually start them to gain control, then taper while adding a steroid-sparing drug.

Surgeries (What is done and why)

1) Symblepharon lysis with amniotic membrane graft
Procedure: Carefully separates scar bands between eyelid and eyeball; places amniotic membrane to cover raw areas and reduce re-adhesion.
Why: To preserve eye movement, comfort, and vision by preventing permanent adhesions.

2) Tarsal fracture/recession and mucous-membrane grafts
Procedure: Repositions eyelid tissues and covers defects with grafts from mouth or other mucosa.
Why: To correct eyelid scarring that rubs the cornea and threatens vision.

3) Punctal occlusion or plugs
Procedure: Temporarily or permanently blocks tear drainage.
Why: To keep tears on the eye surface longer in severe dryness.

4) Airway procedures (e.g., dilation, laser, or tracheostomy in emergencies)
Procedure: ENT surgeons widen narrowed areas or secure the airway when scarring threatens breathing.
Why: To prevent or treat airway compromise.

5) Esophageal dilation (endoscopic)
Procedure: Gently stretches narrowed segments caused by scarring.
Why: To improve swallowing and nutrition when strictures form.

Preventions

1. Keep mucosa moist: regular eye drops/ointments and saliva support.

2. Avoid irritants: smoking, alcohol mouthwash, very hot or spicy foods during flares.

3. Practice gentle oral hygiene with soft tools and SLS-free paste.

4. Manage reflux (meal timing, bed elevation).

5. Use humidifiers for dry indoor air.

6. Protect eyes from wind/dust; wear wraparound glasses outdoors.

7. Maintain nutrition and hydration; choose soft, moist foods during flares.

8. Report any new eye pain, light sensitivity, or vision change immediately.

9. Carry a medication list; inform all providers about fragile mucosa.

10. Keep scheduled visits with dermatology, ophthalmology, ENT, and oral medicine.

When to See Doctors (Urgent and routine)

• Urgent, same day: New eye pain, redness, light sensitivity, sudden vision blur; noisy breathing, shortness of breath; trouble swallowing liquids; mouth bleeding that won’t stop; fever with rapidly worsening sores.

• Soon (within days): New blisters or erosions in eyes, throat, or genitals; painful mouth ulcers preventing eating; weight loss; medication side effects (dark urine, yellow eyes, severe fatigue).

• Routine: Regular follow-up for medication monitoring (blood counts, liver/kidney tests), eye pressure checks if using steroids, and scarring surveillance even if symptoms seem quiet.

What to Eat & What to Avoid

Eat (helps comfort and healing):

1. Soft soups and stews; 2) Yogurt/kefir; 3) Scrambled eggs; 4) Oatmeal with milk; 5) Mashed potatoes with olive oil; 6) Poached fish; 7) Ripe bananas/mango; 8) Avocado; 9) Cottage cheese/soft paneer; 10) Smooth nut butters (if tolerated).

Avoid (during active flares):

1. Very hot drinks; 2) Chili/spicy foods; 3) Acidic foods (citrus, vinegar) if painful; 4) Sharp/abrasive foods (chips, crusty bread); 5) Alcohol and alcohol-based mouthwashes; 6) Smoking/tobacco; 7) Strong mint/cinnamon products if they sting; 8) Carbonated drinks if irritating; 9) Hard candies that rub; 10) Anything that clearly worsens pain on contact.

Frequently Asked Questions

1) Is cicatricial pemphigoid the same as bullous pemphigoid?
No. Both are autoimmune blistering diseases, but cicatricial pemphigoid mainly attacks mucous membranes and scars, especially eyes and throat. Bullous pemphigoid mostly affects skin and scars much less.

2) Can it affect vision?
Yes. Scarring can glue eyelids to the eye and scratch the cornea. Early eye care prevents damage and protects sight.

3) Is it contagious?
No. It is an autoimmune problem and cannot be caught from someone else.

4) How is it diagnosed?
By biopsy from the edge of a fresh lesion and direct immunofluorescence, plus blood tests for antibodies when available.

5) Will it go away on its own?
Usually no. It tends to smolder. Treatment lowers inflammation, prevents scars, and protects function.

6) Do I have to take steroids forever?
Not usually. Steroids may start control quickly, but doctors try to taper and switch to safer long-term medicines.

7) What if medicines don’t work?
Specialists may use rituximab, IVIG, or combine agents. Surgery can manage scarring that blocks vision or swallowing.

8) Can I use home remedies?
You can support healing with moisture care, soft diet, and humidifiers, but don’t replace prescribed medicines with home remedies.

9) Are there triggers?
Irritation, infections, and trauma can worsen lesions. Some medicines rarely trigger similar conditions; ask your doctor before changes.

10) Is it related to cancer?
Most cases are not. A subset with anti–laminin-332 antibodies has been linked to internal cancer risk; your team will guide screening if suspected.

11) Can dental cleanings be done safely?
Yes, with gentle technique, lubrication, and timing around flares. Tell your dentist about your diagnosis.

12) What about pregnancy?
Plan with your specialists; some medicines are unsafe in pregnancy, but care plans can be adjusted ahead of time.

13) Will this affect my voice?
If the voice box is involved, hoarseness can occur. Early ENT care and voice rest help protect your voice.

14) How often should I see the eye doctor?
At diagnosis and regularly afterward—frequency depends on activity. Eye symptoms need prompt review.

15) Can stress make it worse?
Stress does not cause it, but it may worsen flares. Simple stress-reduction habits can help symptoms feel more manageable.
