Your tear system is a small plumbing network. Tears flow from the eye corners through two tiny holes (puncta), into short channels (canaliculi), down into a small pouch (the lacrimal sac) at the inner corner of your eye, and then through the nasolacrimal duct into the nose. A lacrimal sac tumor is an abnormal growth that starts in, or spreads to, this sac. These growths are rare, but they matter because some are cancers that can invade nearby bone, sinuses, or the orbit (eye socket). About half or a little more of lacrimal sac tumors are malignant (cancerous), so doctors take any suspicious sign seriously. EyeWikiScienceDirectPMC
In simple terms: if a lump forms at the inner corner of the eye, especially with persistent tearing or blood-stained tears, doctors want to rule out a tumor and not just assume it’s a routine tear-duct blockage. PMC
How do lacrimal sac tumors behave?
Most tumors in this area begin from the lining (epithelium) of the sac. Among the benign (non-cancerous) ones, papillomas are common and can sometimes transform into cancer if left alone. Among the malignant ones, squamous cell carcinoma (SCC) is the most frequent. These facts shape how doctors think about risk and testing. PMCEyeWiki
Types
To keep things clear, here are the main types grouped by where they come from. Each item includes a two-line explanation in plain English.
Benign epithelial tumors (from the lining)
Exophytic papilloma: A wart-like growth that projects outward into the sac. It is benign but can recur.
Inverted (transitional/Schneiderian) papilloma: The lining grows inward into the tissue. Benign by definition, but it carries a higher risk of turning malignant over time, so doctors watch it closely. HPV can be present in some cases. PMCRhinology JournalEyeWiki
Oncocytoma and other rare adenomas: Tumors from gland-like cells in the lining; generally benign but uncommon.
Malignant epithelial tumors (cancers from the lining)
Squamous cell carcinoma (SCC): Most common lacrimal sac cancer. It behaves like SCC elsewhere in the head and neck—can invade locally and may spread. PMCKarger
Transitional (urothelial-type) cell carcinoma: Arises from transitional-type lining; can be aggressive; bloody tears may rarely be the presenting clue. PMCScienceDirect
Adenocarcinoma / mucoepidermoid carcinoma: Gland-forming cancers; uncommon but important to recognize. PMC
Non-epithelial tumors
Lymphoma (e.g., MALT lymphoma, diffuse large B-cell lymphoma): Cancers of immune (lymphoid) tissue that can involve the lacrimal sac; sometimes linked with long-standing inflammation. Lippincott JournalsPMC
Melanoma: Very rare, but reported; may be mistaken for chronic infection at first. PMCBioMed Central
Sarcomas (connective-tissue cancers): Rare tumors from muscle, fibrous tissue, or blood vessels.
Metastases or extension from nearby sinonasal tumors: The sac sits next to the nose and sinuses, so cancers from there can extend into it.
Tumor-like lesions (not true tumors) that can mimic tumors
Inflammatory masses, granulomas, mucoceles, and polyps: These swellings can look and feel like a tumor but are driven by inflammation, blockage, or infection rather than uncontrolled cell growth.
Causes
Here “cause” is used broadly to mean the conditions or pathologies that can produce a lacrimal sac mass, including true tumors and tumor-like lesions. Each item includes a very short “why it happens” note.
Squamous cell carcinoma (SCC) — malignant change of lining cells; most common cancer here. PMC
Transitional cell carcinoma — cancer from transitional-type epithelium; can follow or arise alongside papillomas. ScienceDirect
Adenocarcinoma — cancer from gland-like cells in the lining. PMC
Mucoepidermoid carcinoma — mixed gland and squamous features; uncommon but documented. PMC
Exophytic papilloma (benign) — overgrowth of lining; may recur.
Inverted/transitional papilloma (benign with malignant potential) — inward-growing papilloma with risk of transformation; HPV can be detected in some benign and malignant transitional tumors. PMCRhinology Journal
Oncocytoma/other benign adenomas — benign glandular-type tumors.
MALT lymphoma — a B-cell lymphoma often linked to chronic mucosal inflammation. PMC
Diffuse large B-cell lymphoma (DLBCL) — aggressive lymphoma; can arise primarily in the sac. Lippincott Journals
Melanoma — malignant tumor from pigment cells; extremely rare in this location. PMC
Inflammatory pseudotumor — mass-like inflammation that mimics cancer.
Granulomatous diseases (e.g., sarcoid, TB) — chronic immune reactions forming masses.
Mucocele — mucus-filled expansion from chronic blockage, expanding the sac.
Sinonasal inverted papilloma with sac involvement — nasal tumor growing into the sac. PMC
Secondary spread from adjacent sinonasal carcinoma — direct extension across thin bone partitions.
Vascular tumors (hemangioma, etc.) — uncommon, but can form sac masses.
Fibrous tumors (e.g., fibrous histiocytoma) — rare connective tissue growths.
Trauma-related scarring with polypoid change — post-injury remodeling can create mass-like lesions.
Chronic dacryocystitis with reactive polyps — long-standing infection/obstruction can create polypoid tissue that looks tumorous.
Metastatic deposits (rare) — spread from cancers elsewhere (e.g., kidney, skin) reaching the sac via blood or extension.
Symptoms and signs
Below are the common everyday words people use, plus simple explanations of what each suggests.
Epiphora (watery eye that doesn’t stop): The most frequent symptom; tears cannot drain properly because the sac or duct is blocked or narrowed by a mass. ScienceDirect
A firm swelling at the inner corner (medial canthus): A persistent, sometimes painless lump near the bridge of the nose. A mass that extends above the medial canthal tendon makes doctors worry more about malignancy. PMC
Recurrent “dacryocystitis-like” episodes: Redness, tenderness, and discharge that keep coming back even after antibiotics—this pattern raises suspicion of an underlying tumor rather than simple infection. EyeWiki
Blood-stained tears (haemolacria): Not common, but a red flag for a tumor of the lacrimal drainage pathway. Seek specialist care urgently. PMC
Mucus or pus discharge from the inner corner: Caused by retained secretions infected behind a blockage.
Pain or pressure at the inner corner of the eye: More likely with active infection or rapidly growing masses.
A feeling of nasal blockage on the same side: The sac drains into the nose, so larger masses can cause nasal stuffiness.
Visible skin changes over the lump: The skin may become shiny, stretched, reddish or develop a sinus if the mass inflames or ulcerates.
New tearing after prior DCR surgery: A return of tearing soon after or despite surgery can be a clue that the original problem was not simple obstruction. (Doctors specifically consider tumor in this scenario.) PMC
Eye movement discomfort or double vision: Suggests local spread toward the orbit (eye socket).
Proptosis (eye looks pushed forward): Seen in large or invasive tumors. PMC
Numbness near the cheek or upper teeth: Rare, but perineural spread into nearby nerves can cause altered sensation. Radiopaedia
Persistent crusting at the inner corner: From constant overflow and low-grade infection.
Bad smell from the nose on that side: Can occur with infected, obstructed secretions.
General unwell feeling, fever during flare-ups: When infection overlies the blockage (dacryocystitis).
Diagnostic tests
A) Physical exam (bedside observations and maneuvers)
Careful inspection of the inner corner: The doctor looks for a mass above or below the medial canthal tendon, skin changes, or a fistula. A firm, fixed mass—especially one extending upwards—is worrisome for malignancy. PMC
Palpation of the lacrimal sac area: Gentle pressure may express mucus or blood through the punctum; blood-tinged reflux is a red flag. PMC
ROPLAS (Regurgitation On Pressure over the LAcrimal Sac): The clinician presses over the sac to see if fluid regurgitates through the punctum. It’s quick; specificity is very high (a positive test strongly indicates obstruction), but sensitivity is modest (a negative test doesn’t rule out disease). PMCPubMed
Lid and conjunctival eversion: To exclude conjunctival, caruncular, or canalicular sources of bleeding or masses that can masquerade as sac disease. PMC
Anterior rhinoscopy or office nasal endoscopy (basic look in the nose): Helps identify nasal polyps, masses, or an obvious lesion near the duct opening.
B) Manual/office lacrimal tests (simple tools in the clinic)
Lacrimal irrigation (syringing): Saline is gently injected through the punctum; easy wash-through suggests patency; reflux under pressure suggests obstruction or a sac lesion.
Probing of the canaliculi: A blunt probe maps the channel; a “hard stop” suggests normal anatomy; a “soft stop” can suggest canalicular disease or a mass.
Fluorescein Dye Disappearance Test (FDDT): A drop of dye is placed in each eye; dye that lingers (compared with the other eye) suggests outflow problems. Strongly abnormal tests correlate with obstruction, but a normal result does not always mean the system is healthy. PubMed
Jones Test I: After dye is instilled, a swab in the nose tests whether dye reached the nasal cavity. Used less often today; a negative result suggests blockage somewhere in the pathway. NCBIEyeWiki
Jones Test II: Performed if Jones I is negative; irrigation pushes dye through to see where the block sits. Also less commonly used now. EyeWiki
Micro-Reflux Test (MRT): A quick screening maneuver described for primary nasolacrimal duct obstruction; not routine everywhere, but part of the lacrimal testing toolbox. ScienceDirect
Cytology of refluxed material: If mucus or blood is expressed, it may be sent for cytology; this can occasionally pick up malignant cells but is less definitive than a biopsy.
C) Laboratory & pathological tests (the definitive ones)
Incisional or excisional biopsy of the lacrimal sac lesion: This is the gold standard for a suspected tumor. Tissue is examined under the microscope with special stains. (In surgical practice, biopsies at or after DCR occasionally uncover unsuspected tumors.) EyeWiki
Routine histopathology (H&E): Shows whether the lesion is benign or malignant and identifies the specific type (e.g., SCC, lymphoma, papilloma).
Immunohistochemistry (IHC): Panels like cytokeratins for carcinomas, CD20/CD79a for B-cell lymphomas, S100/HMB-45 for melanoma help pin down the exact diagnosis.
HPV testing (p16 IHC or PCR) for transitional lesions: Transitional papillomas/carcinomas may harbor low-risk (6/11) or high-risk (16/18) HPV; results can inform prognosis in some settings. Rhinology Journal
Flow cytometry (for lymphoma): Analyzes cell markers to subtype lymphomas (e.g., MALT vs DLBCL). Lippincott Journals
D) Electrodiagnostic tests
Visual Evoked Potential (VEP): If there’s concern the tumor has affected the optic pathway (rare for sac lesions), VEP can check optic nerve function.
Electromyography (EMG) or nerve studies: Seldom used; only considered when there is suspected nerve involvement causing eye movement or facial sensation changes.
(Note: These are not routine for lacrimal sac tumors; they’re mentioned for completeness.)
E) Imaging tests (show the size, extent, and spread)
CT scan of orbits and paranasal sinuses: Shows a soft-tissue mass at the medial canthus, any bony remodeling or widening of the bony canal, and involvement of adjacent sinus walls. Great for bone detail. Radiopaedia
MRI of orbits/nose: Shows a moderately enhancing mass at the medial canthus and maps soft-tissue spread; radiologists also look for perineural spread along nearby nerves. Radiopaedia
Dacryocystography (contrast X-ray of the tear pathway): Contrast dye outlines the sac/duct and can show a filling defect from a mass.
Dacryoscintigraphy (nuclear medicine): A physiologic drainage test used more for functional obstruction, but in a tumor work-up it can help confirm outflow failure patterns. Medscape
Ultrasound (high-frequency): May visualize a cystic vs solid mass and guide procedures in experienced hands.
PET-CT (in selected cancers): Helps stage more aggressive tumors or lymphomas by looking for other involved sites.
Office nasal endoscopy (with camera): Not an “imaging” in the radiology sense, but a direct view inside the nose to check the duct opening and look for a sinonasal source.
Non-pharmacological treatments
These help with diagnosis, symptom control, recovery, or long-term function. They do not replace surgery or oncologic therapy when cancer is present.

Dietary molecular & supportive supplements
These do not treat the tumor, but can support overall health and treatment tolerance. Always clear supplements with your doctors to avoid interactions (especially during chemo-immunotherapy).
High-protein medical nutrition shakes – help wound healing and maintain weight during RT/chemo.
Vitamin D (e.g., 800–2000 IU/day if deficient per clinician) – supports bone/muscle and possibly immunity; dose guided by blood levels.
Omega-3 (fish oil 1–2 g/day EPA/DHA) – may aid appetite and reduce inflammation; stop before surgery if told.
Oral rehydration solution – maintains electrolytes if mucositis or poor intake.
Probiotics (oncology-approved strains) – may support gut health during antibiotics/chemo; use only if neutrophil counts are safe.
Zinc (short course if low) – supports taste recovery and wound healing; avoid high chronic doses.
Selenium (if deficient) – antioxidant cofactor; clinical guidance needed.
B-complex – supports energy metabolism; avoid megadoses.
Iron only if iron-deficient – corrects anemia; never take empirically.
Magnesium – helpful if low, especially with cisplatin causing losses; dosing per labs.
Glutamine (for mucositis, per team protocol) – mixed data; only if your center endorses it.
Turmeric/curcumin – potential anti-inflammatory; avoid with chemotherapy unless cleared (drug interactions).
Green tea extract – antioxidant; avoid concentrated forms during chemo (interactions).
Fiber (psyllium/oats) – regularity and microbiome support.
Multivitamin (no iron unless needed) – broad micronutrient coverage at standard daily doses.
Regenerative / stem-cell drugs
There are no approved regenerative or stem-cell drugs for lacrimal sac tumors. Stem-cell products marketed for “cancer repair” or “immune boosting” are unproven and potentially dangerous. What is evidence-based: immunotherapies like pembrolizumab and nivolumab for selected, advanced head-and-neck–type cancers, and rituximab-based chemo for lymphomas, as covered above. Rare biomarker-positive tumors (e.g., HER2-positive SCC) may be considered for trastuzumab-based approaches in expert centers or clinical trials. FDA Access Data+1Karger
Surgeries
En-bloc resection of the lacrimal sac and nasolacrimal duct
Why: First-line for resectable epithelial cancers to obtain clear margins.
What happens: Surgeon removes the sac with surrounding soft tissue ± part of adjacent bone (medial maxilla) as one piece. NatureMedial maxillectomy (external or endoscopic)
Why: If tumor extends into the lateral nasal wall or maxillary sinus.
What happens: Remove the medial wall of the maxilla to clear margins while preserving as much function as possible. NatureEndoscopic dacryocystorhinostomy (DCR) for benign or adjunct indications
Why: Restore tear drainage in benign disease; provide access/biopsy; not curative for cancer.
What happens: Create a new path from sac to nose with stent placement. NCBIJohns Hopkins MedicineOrbitotomy ± reconstruction
Why: If tumor touches or enters the orbit; allows precise removal and repair.
What happens: Open a safe window to the orbit; resect tumor; reconstruct with plates/grafts as needed.Orbital exenteration (rare, last resort)
Why: Very advanced, destructive tumors when eye-sparing is impossible.
What happens: Remove orbital contents; later fit cosmetic prosthesis; reserved for life-saving situations. PMC
Prevention tips
While you cannot “prevent” most lacrimal sac tumors, you can lower risks and shorten time to diagnosis:
Don’t ignore persistent tearing or a firm inner-corner lump that doesn’t decompress.
Seek care for recurrent “tear-duct infections” that do not fully resolve.
Quit smoking; avoid workplace carcinogens; use protective masks when appropriate.
Keep nasal allergies/sinusitis controlled to reduce chronic inflammation.
Maintain regular eye and ENT check-ups if you have chronic tearing.
Protect from chronic UV exposure (eye area skin).
Keep good hygiene around the eyelids.
Manage HPV risk (safe practices; vaccination per national guidance).
Keep nutrition and oral health strong—better treatment tolerance if needed.
Follow surveillance schedules after treatment to catch recurrences early. ScienceDirect
When to see a doctor—right away
Tearing plus a firm, non-compressible mass at the inner corner of the eye.
Recurrent “tear-duct infections,” blood-stained tears, or nosebleeds on the same side.
New double vision, eye pain, or vision change.
Facial numbness or swelling near the nose and cheek.
Symptoms that persist beyond 2–4 weeks despite usual blocked-duct care.
What to eat and what to avoid
What to eat:
Protein-rich foods (fish, eggs, legumes, dairy/soy) at every meal to help healing.
Colorful fruits and vegetables (5+ servings/day) for vitamins, minerals, and fiber.
Whole grains for steady energy.
Healthy fats (olive oil, nuts, seeds; omega-3 fish like salmon).
Plenty of fluids (water, oral rehydration if needed during RT/chemo).
What to avoid or limit:
Tobacco and excess alcohol—they impair healing and raise risk in head-and-neck sites.
Very spicy/acidic foods if you develop mucositis during RT/chemo.
Raw or unpasteurized foods when neutrophil counts are low (your team will advise).
High-dose antioxidant supplements during active RT/chemo unless your oncologist approves (they can interfere with treatment).
Frequently asked questions
Is a lacrimal sac tumor the same as a blocked tear duct?
No. Many tumors look like a simple blockage at first. If tearing persists or there’s a firm mass or bleeding, specialists should check for a tumor.Are most lacrimal sac tumors cancer?
Not always. Papillomas are benign but can recur and sometimes transform. Malignant tumors like SCC do occur and need urgent treatment. EyeWikiWhat is the main treatment for cancer in the lacrimal sac?
Complete surgical removal with adjuvant radiotherapy is the backbone when the tumor is resectable. NatureScienceDirectCan these cancers be treated without surgery?
If surgery isn’t possible, definitive radiotherapy with concurrent chemotherapy may control disease in selected cases. PMCWhat are the chances of saving the eye?
Many early tumors are treated with eye-sparing surgery; advanced cases may need more extensive operations. Early diagnosis helps preserve eye and function. BioMed CentralDo I need chemotherapy?
It depends on the tumor type and stage. Epithelial cancers may get radiosensitizing cisplatin with RT; lymphomas usually need R-CHOP-based chemo. ASCO PublicationsPubMedWhat about immunotherapy?
Drugs like pembrolizumab and nivolumab are used for certain advanced or metastatic head-and-neck cancers and can be considered case-by-case for lacrimal sac cancers with the right markers. FDA Access Data+1Are there targeted therapies?
Occasionally, yes—rare HER2-positive tumors may be considered for trastuzumab-based strategies in expert centers. KargerHow is lymphoma of the lacrimal sac treated?
Often with R-CHOP chemo-immunotherapy, sometimes followed by localized radiotherapy; outcomes are generally favorable when diagnosed early. PubMedPMCWill I lose my hair?
Only if you receive certain chemotherapies (e.g., R-CHOP). Surgery and radiation alone do not usually cause total hair loss.Can I wear contact lenses?
During active infection, post-op healing, or RT/chemo affecting the ocular surface, it’s better to pause contacts until your team clears you.How long is recovery after surgery?
Minor endoscopic procedures recover in weeks; larger resections take longer and may need staged reconstruction. Your surgeon will set expectations.What side effects should make me call urgently?
Fever, severe pain, sudden vision change, nosebleeds that won’t stop, swelling that rapidly worsens, or any sign of allergic reaction to medications.How often will I be followed?
Typically every 3–6 months at first, then yearly if stable. Imaging/endoscopy frequency depends on your pathology and stage. ScienceDirectAre stem-cell or “immune-boosting” shots helpful?
No approved stem-cell or “immune-boost” products treat these tumors. Stick to proven therapies guided by your specialists. FDA Access Data+1
