Epibulbar Subconjunctival Apocrine Hidrocystoma

Apocrine hidrocystomas are benign cystic tumors derived from apocrine sweat glands; they are most commonly located in the skin of the head and neck regions. Ophthalmic occurrences characteristically appear at the lash line and canthi of the eyelid, although rare instances have been described in the conjunctiva, caruncle, and orbit. The authors describe an exceptional instance of a mobile epibulbar subconjunctival apocrine hidrocystoma in a 57-year-old woman without a history of previous ocular injury or surgery. Histopathology of the excised specimen displayed an empty cyst lined by a double layer of cuboidal epithelium with the inner layer exhibiting periodic acid-Schiff-positive apical decapitation secretion. Confirmatory immunohistochemistry included reactivity with cytokeratin-7, smooth muscle actin, D2-40, and CDGFP-15.
