Steatocystoma simplex of the caruncle.

CASE REPORT: The authors present a rare case of steatocystoma simplex occuring in the caruncle. A 42-year-old male presented with an asymptomatic, yellow soft mass in the medial canthal area of the left eye. An excisional biopsy was performed, and the mass lesion was diagnosed as steatocystoma by histological examination. COMMENTS: Steatocystoma simplex should be considered one of the differential diagnoses for patients with an asymptomatic mass lesion in the caruncle.
