A Case of Steatocystoma Simplex and Sebaceous Gland Hyperplasia of the Bilateral Lacrimal Caruncle

Purpose: A case of bilateral lacrimal caruncle steatocystoma simplex and sebaceous gland hyperplasia, which rarely occurs in the periocular area, is reported. Case summary: A 42-year-old female presented with a bilateral caruncular mass, which had been growing for a few months. A physical examination revealed soft, non-tender, rounded masses and no other ophthalmic findings. Under local anesthesia, the masses were completely excised. In the histopathological examination, a cystic mass containing a sebaceous gland in the stratified squamous epithelium cyst wall was found. A hyperplastic sebaceous gland and a dilated sebaceous gland duct were also found. Steatocystoma simplex and sebaceous gland hyperplasia, respectively, were diagnosed. There was no recurrence or complication after excision. Conclusions: Steatocystoma simplex and sebaceous gland hyperplasia are benign tumors that rarely occur in the lacrimal caruncle. They can be diagnosed and treated by complete excision. Steatocystoma simplex and sebaceous gland hyperplasia should therefore be considered as differential diagnoses of a lacrimal caruncle mass.
