A recurrent chalazion that becomes yellowish with surrounding madarosis raises concern for which ocular malignancy?

• A. Sebaceous gland carcinoma
• B. Basal cell carcinoma
• C. Squamous cell carcinoma
• D. Malignant melanoma

Answer: (A)

A recurrent chalazion that becomes yellowish with surrounding madarosis points to a malignant process arising from the meibomian glands, specifically sebaceous gland carcinoma. This tumor originates in the meibomian glands of the tarsal plate and often masquerades as a chalazion because it creates a persistent, firm lid swelling that can intermittently recur. The yellow, lipid-rich appearance reflects the sebaceous origin of the cells, and madarosis (loss of eyelashes) occurs as the tumor invades the lash follicles and adjacent lid margin. Because it can spread within the eyelid and onto the conjunctiva (pagetoid spread) and because early stages may resemble a benign chalazion, a high index of suspicion and prompt biopsy are crucial.

Basal cell carcinoma tends to present as a pearly, telangiectatic lid lesion, often on the lower lid, rather than as a recurrent chalazion with madarosis. Squamous cell carcinoma typically shows an indurated mass with ulceration or crusting. Malignant melanoma usually presents as a pigmented or variably pigmented lid lesion, which is not the classic description here. The combination of a recurrent chalazion-like lesion with yellowish coloration and lash loss most strongly implicates sebaceous gland carcinoma.
