A 68-year-old man presented with a mass at the right canthus for >30 years. Examination revealed a yellowish-white, firm, mobile tumor on the right caruncle, with defined borders. The surface was irregular with abundant blood supply (A). Pathological and immunohistochemical examination confirmed a sebaceous adenoma of the caruncle. Hematoxylin-eosin staining revealed polygonal tumor cells arranged in nests. Central tumor cells displayed foamy cytoplasm (asterisks), with well-defined sebaceous lobules of varying sizes and shapes (B).
