Chalazion – Right Lower Eyelid: Complete Case Presentation Guide
Based on your case sheet: 17-year-old male, painless round swelling over the right lower eyelid (RT LEL) x 1 month, firm, fixed to tarsal plate, fluctuation and transillumination negative — this is a classic Chalazion. Below is the full presentation exactly as an examiner expects it — history → examination → differential → diagnosis — with the reasoning behind every point, model phrasing, and likely viva questions. Sources: Kanski's Clinical Ophthalmology, 10th ed. and The Wills Eye Manual (cross-checked against your library), supplemented with standard clinical-examination teaching used in PG ophthalmology practical books (Prafulla/PK Mukherjee-style case format).
HOW TO OPEN THE CASE
"Sir/Madam, I have examined Master [patient's name], a 17-year-old male, resident of Khodiyar Colony, Jamnagar, who presents with a chief complaint of swelling over the right lower eyelid since 1 month."
1. HISTORY — Point by Point
A. Chief Complaint
- Presented as: "Swelling in the right lower eyelid × 1 month."
- Why this matters: Always state site + nature + duration. This triad orients the examiner immediately toward a lid-lesion differential.
- Examiner Q: "Why do you ask duration first?" A: Duration separates acute lesions (hordeolum, insect bite, cellulitis – days) from chronic lesions (chalazion, cyst, tumour – weeks to months). A 1-month painless swelling already biases you away from an acute infective process.
B. History of Presenting Illness (HPI)
Model phrasing:
"The patient was apparently asymptomatic 1 month back, when he noticed a small, painless swelling over the right lower eyelid. The swelling was insidious in onset and gradually progressive in size, not associated with pain, redness, discharge, watering, photophobia, or diminution of vision."
Break this into the 7 mandatory descriptors examiners look for in any swelling history, and how to phrase the negative screen:
| Descriptor | What you say | Why it's asked |
|---|---|---|
| Onset | Insidious | Insidious onset → chronic granulomatous process (chalazion), not acute abscess (hordeolum) |
| Progression | Gradual, static/increasing | Slow growth → benign; rapid growth in an adult → raises suspicion of sebaceous gland carcinoma |
| Pain | Absent | Chalazion is classically painless unless secondarily infected (→ internal hordeolum) |
| Redness | Absent | Absence rules against acute inflammation/infection |
| Discharge/watering | Absent | Rules out lacrimal pathology, ruptured abscess |
| Photophobia | Absent | Rules out corneal/uveal involvement |
| Diminution of vision (DOV) | Absent | Important negative — large chalazia can press on cornea and induce astigmatism/blur; asking this is mandatory even if the swelling looks trivial |
Examiner Q: "Why do you specifically ask about DOV in an eyelid swelling?"
A: A large chalazion can mechanically indent the cornea and cause induced (with-the-rule) astigmatism, giving blurred vision. Absence of DOV here tells you the lesion is small/not exerting pressure effect — consistent with the 0.4 × 0.4 cm size measured later.
Examiner Q: "Why no pain in chalazion but pain in stye/hordeolum?"
A: Chalazion is a sterile, chronic lipogranulomatous reaction to retained meibomian secretions — no active bacterial infection, hence no pain. Hordeolum is an acute staphylococcal abscess, hence pain, redness, and tenderness are expected.
C. Past History
"No history of similar swelling in the past, no history of trauma or surgery to the eye, no history of any systemic illness (diabetes, thyroid disorder, tuberculosis)."
Why asked:
- H/o trauma/surgery — rules out post-traumatic cyst/foreign body granuloma.
- H/o systemic illness — diabetes and immunosuppression predispose to recurrent chalazia and delayed healing (relevant if surgery is planned); rosacea/seborrheic dermatitis are classic associations with recurrent multiple chalazia.
Examiner Q: "What systemic associations does chalazion have?"
A: Blepharitis, acne rosacea, seborrheic dermatitis, and (rarely) bortezomib therapy (proteasome inhibitor used in multiple myeloma) — Kanski's Clinical Ophthalmology, 10th ed.
D. Personal History
"Diet – mixed, sleep and appetite adequate, bowel and bladder habits regular, no addictions." Why asked: Standard for every case; also screens for pre-anaesthetic fitness if minor OT procedure (incision and curettage) is planned.
E. Family History
"No similar complaints in the family." Why asked: Chalazia themselves aren't hereditary, but this question screens for familial skin conditions (rosacea, atopic dermatitis, blepharitis) that predispose to recurrent lesions.
2. GENERAL EXAMINATION
"Patient is conscious, well-oriented, moderately built and well-nourished. Vitals are stable. No pallor, icterus, cyanosis, clubbing, lymphadenopathy or edema."
Why do a general exam for an eyelid swelling?
- To confirm fitness for a minor lid procedure under local anaesthesia.
- Pallor/lymphadenopathy screen — if this were instead a suspicious eyelid mass in an older patient, regional (pre-auricular/submandibular) lymphadenopathy would be a red flag for malignancy (sebaceous gland carcinoma, squamous cell carcinoma). In a 17-year-old with a classic chalazion, this is a negative screening step, but you must still say it aloud — examiners specifically check whether candidates skip it.
3. OCULAR EXAMINATION (routine, both eyes, every case)
| Parameter | RE | LE | Significance |
|---|---|---|---|
| Vision (unaided) | 6/6 | 6/6 | Normal — confirms no visual axis/corneal involvement |
| Refraction (autorefraction) | +0.75 × 161 / +0.25 | +0.75 × 150 / +0.00 | Low hypermetropic astigmatism, physiological, not lesion-induced (compare axis/power between the eyes — roughly symmetrical, so not attributable to the chalazion) |
| Vision with correction | 6/6 | 6/6 | Confirms full correctability, no amblyopia |
Examiner Q: "Why check vision and do refraction in a case of eyelid swelling?"
A: Two reasons — (1) documentation/medico-legal baseline before any procedure, and (2) to actively rule out lesion-induced astigmatism from pressure on the globe. Since VA is 6/6 in both eyes and the astigmatism is small, symmetric, and low-grade, it is physiological, not related to the chalazion.
4. ANTERIOR SEGMENT EXAMINATION (O/E A/S) — say this structure out loud, both eyes compared
Go lid → conjunctiva → cornea → anterior chamber → iris → pupil → lens → fundus glow, right eye then left, in one continuous sentence per structure:
| Structure | RE | LE |
|---|---|---|
| Lids | Chalazion over lower lid (the lesion) | Normal |
| Conjunctiva | No congestion | No congestion |
| Cornea | Clear | Clear |
| Anterior chamber | Deep and quiet (++) | Deep and quiet (++) |
| Iris | Pattern well seen | Pattern well seen |
| Pupil | Normal size, round, reacting to light | Normal size, round, reacting to light |
| Lens | Clear | Clear |
| Fundus glow | Within normal limits, obtained on cover | Within normal limits, obtained on cover |
Why examine the fellow eye/rest of the anterior segment when the complaint is a lid swelling? Because a "focused" exam without a full ocular check is heavily penalized — you must show the lesion is isolated to the lid and there is no associated conjunctivitis, keratitis, uveitis, or blepharitis affecting the globe.
5. LOCAL EXAMINATION OF THE SWELLING (this is the core of the case — go slow here)
(a) INSPECTION
State each point with the reason you're looking for it:
| Point | Finding | What you're screening for |
|---|---|---|
| Site | Right lower eyelid | Chalazion occurs in tarsal (meibomian) gland-bearing skin — upper or lower lid; hordeolum externum occurs strictly at the lid margin |
| Number | Single | Multiple lesions suggest rosacea-associated chalazia or molluscum |
| Shape | Round | Cystic/granulomatous lesions are typically round/oval; irregular shape raises suspicion of malignancy |
| Size | 0.4 × 0.4 cm² | Document precisely — used to monitor response to conservative treatment |
| Surface | Smooth | Irregular/nodular surface with ulceration → suspect sebaceous gland carcinoma |
| Colour | Same as overlying skin | A chalazion lies deep to skin (in the tarsal plate) so skin colour is usually unchanged, unlike a hordeolum which is red and inflamed |
| Margin | Well defined | Well-circumscribed → benign; ill-defined/infiltrative margin → malignant |
| Secondary changes | Absent — no ulceration, no discharge | Rules out infected/discharging sinus, malignant ulceration |
| Eyelashes | Normal | Madarosis (loss of lashes) overlying a recurrent lid lump in an older patient is a classic red flag for sebaceous gland/meibomian gland carcinoma |
| Position of lid | Normal, no ptosis, no ectropion/entropion | Large chalazia can mechanically cause mild ptosis; must be documented as absent |
Examiner Q: "Why check eyelashes specifically?"
A: Madarosis with a recurrent, non-resolving "chalazion" in an elderly patient is one of the classic masquerade signs of sebaceous gland carcinoma — Kanski explicitly recommends biopsy of any chalazion recurring in the same position in an older patient.
(b) PALPATION
| Point | Finding | What it tells you |
|---|---|---|
| Local temperature | Normal | No active inflammation/infection — against hordeolum/cellulitis |
| Tenderness | Absent | Chalazion is classically non-tender (tender = hordeolum, infected chalazion, cellulitis) |
| Consistency | Firm | Granulomatous tissue is firm; a fluid-filled lesion (sebaceous cyst) would feel soft/cystic |
| Mobility | Free from overlying skin, fixed to the tarsal plate | This is the single most important discriminating sign. Chalazion arises from the meibomian gland within the tarsal plate, so it moves with the tarsus but the skin glides freely over it. A sebaceous (epidermal) cyst, by contrast, is attached to skin and mobile over deeper tissue — exactly the opposite pattern. |
| Fluctuation test | Negative | Confirms the lesion is solid/granulomatous, not a fluid-filled cyst or abscess |
| Transillumination test | Negative | Confirms the lesion is not translucent/cystic (a dermoid or simple sebaceous cyst transilluminates; lipogranulomatous chalazion tissue does not) |
Examiner Q: "How do you specifically perform the fluctuation test on an eyelid?"
A: Two fingers are placed on either side of the swelling; pressure with one finger is felt as a fluid wave/bulge by the other finger if the lesion is fluctuant (cystic/fluid-filled or abscess). Absence of this transmitted impulse = negative, consistent with a solid granuloma.
Examiner Q: "How is transillumination done and what does a positive result mean?"
A: A pen-torch/light source is applied to the skin surface of the lesion in a darkened room. A cystic, fluid-filled lesion (dermoid, simple sebaceous cyst) glows/transilluminates (positive); a solid lesion like chalazion (composed of lipid-laden granulomatous tissue and giant cells) does not transilluminate (negative).
Examiner Q: "Why did you not just diagnose it as a 'cyst' on inspection alone?"
A: Because the fixity to the tarsal plate plus negative fluctuation and transillumination together confirm it is a solid granulomatous lesion of the meibomian gland rather than a true epithelial-lined cyst — this combination of findings is what clinically defines chalazion versus its mimics.
(c) Lid Eversion (mention this even if not explicitly in your notes — examiners often ask)
Why do it: To look at the tarsal conjunctival surface for a grey/yellow granuloma pointing internally, and to plan the surgical approach (posterior/conjunctival incision for I&C).
Examiner Q: "What would you expect to see on everting the lid?"
A: A localized area of conjunctival injection/granulomatous elevation corresponding to the involved meibomian gland, sometimes with a visible plug of inspissated secretion at the gland orifice.
6. DIFFERENTIAL DIAGNOSIS
| Condition | Key distinguishing features vs. this case |
|---|---|
| Internal hordeolum | Acute, painful, tender, warm, red — abscess of meibomian gland; this lesion is painless, non-tender, 1-month duration → against it |
| External hordeolum (stye) | Painful, tender nodule strictly at the lid margin, from a gland of Zeis/Moll; ours is painless and (per site) not confined to the margin |
| Sebaceous (epidermal) cyst | Soft/cystic, mobile with the skin, may show a central punctum, positive transillumination; ours is firm, fixed to tarsus, transillumination negative |
| Dermoid cyst | Congenital, present since childhood, usually at the outer canthus/brow, cystic and transilluminates; ours acquired at 17 yrs, over lower lid, solid |
| Molluscum contagiosum | Small, umbilicated, often multiple papules with waxy surface; ours is a single non-umbilicated round swelling |
| Xanthelasma | Yellowish, soft, plaque-like lesion typically at the medial canthus, bilateral, associated with dyslipidemia; ours is firm, skin-coloured, unilateral |
| Papilloma | Pedunculated, papillomatous/warty surface; ours has a smooth surface and is not pedunculated |
| Preseptal cellulitis | Diffuse lid swelling with erythema, warmth, tenderness, often fever; ours is localized, afebrile, non-tender |
| Sebaceous gland carcinoma (meibomian gland carcinoma) | Consider especially in elderly patients with recurrent chalazion, madarosis, irregular margins, or ulceration; important masquerade to exclude but unlikely here given the patient's young age (17 yrs), first episode, well-defined margins, and no madarosis |

7. DIAGNOSIS
Clinical Diagnosis: Chalazion of the right lower eyelid.
Justification (say this as your closing statement):
"A 17-year-old male with a 1-month history of a painless, gradually progressive, round, firm swelling over the right lower eyelid, well-defined, smooth-surfaced, non-tender, with normal local temperature, fixed to the tarsal plate but free from overlying skin, and negative fluctuation and transillumination tests — is consistent with a chalazion, a chronic sterile lipogranulomatous inflammation of the meibomian gland secondary to duct obstruction and retained sebaceous secretion."
8. EXTRA THEORY (for viva depth)
Pathogenesis (Kanski, 10th ed.): Obstruction of a meibomian gland (occasionally a gland of Zeis) duct → retained lipid-rich secretion acts as a foreign body → sterile lipogranulomatous inflammatory reaction. Histopathology shows a lipogranuloma: epithelioid cells, multinucleated giant cells, and lymphocytes surrounding empty spaces where lipid was dissolved out during tissue processing.
Glands of the eyelid (commonly asked):
- Meibomian (tarsal) glands — sebaceous, embedded in the tarsal plate, open at the lid margin — site of origin of chalazion/internal hordeolum.
- Glands of Zeis — sebaceous glands associated with lash follicles — site of external hordeolum.
- Glands of Moll — modified apocrine sweat glands at the lid margin.
Management (staged, as taught in Kanski):
- Conservative — at least a third resolve spontaneously; warm compresses several times a day, lid massage.
- Expression — compressing the lesion between two cotton-tipped applicators for a fresh lesion near the margin.
- Intralesional steroid injection — triamcinolone acetonide, effective in ~80% after one injection (repeat at 1–2 weeks if needed); preferred for marginal lesions or those near the punctum to avoid surgical damage; risk of local skin depigmentation/fat atrophy (rare) and, very rarely, retinal vascular occlusion.
- Incision and curettage (I&C) — under local anaesthesia, using a chalazion clamp to evert and stabilize the lid; a vertical incision is made on the tarsal conjunctiva (perpendicular to the lid margin) to avoid transecting multiple adjacent meibomian glands, followed by curettage of the granulomatous contents.
- Oral antibiotics — only if there is significant secondary bacterial infection (i.e., it has evolved into an internal hordeolum), not for simple sterile chalazion.
- Biopsy — mandatory for any chalazion that recurs in the same site, especially in an older patient, to exclude masquerading sebaceous gland carcinoma.
Complications: recurrence, secondary infection (→ internal hordeolum/preseptal cellulitis), induced corneal astigmatism from pressure on the globe (if large), residual conjunctival granuloma or scarring after I&C.
No recent systematic review/meta-analysis in the last 2 years was found that contradicts this standard conservative → intralesional steroid → I&C management ladder, so the Kanski-based approach above remains current.
