title: Multiple eyelid apocrine hidrocystoma in a domestic short-haired cat.
abstract: A 12-year-old domestic short-haired cat was referred for evaluation of periocular masses. The tail had similar masses and was amputated previously by the referring veterinarian. On examination, multiple pigmented nodules, 3-15 mm in diameter, were found in the periocular skin, primarily involving the palpebral eyelid margin. A wedge excisional biopsy revealed small cuboidal cells forming multiple tubular and cystic structures indicative of apocrine cystadenomas, similar to apocrine hidrocystomas described in humans. The nodules were lanced followed by liquid nitrogen cryofreezing.
