Sebaceous Adenoma of the Caruncle

A 51-year-old man presented with a 10-year history of a gradually enlarging, asymptomatic, left medial canthus mass (Fig 1). Hematoxylin and eosin stain of the excised lesion revealed hyperplastic sebaceous glands forming irregular-shaped lobules with lumina containing proteinaceous material (asterisks) consistent with sebaceous adenoma (Figs 2 and 3). Although this patient was found to be otherwise healthy, a solitary sebaceous adenoma may be associated with malignancies of the gastrointestinal tract or other viscera (Muir-Torre syndrome).
