Rare Presentation of Apocrine Hidrocystoma Along the Nasolacrimal Duct.

ABSTRACT

Hidrocystomas are rare benign cystic tumors of the sweat glands, with no cases of hidrocystoma of nasolacrimal duct previously reported. We present a case of a 28-year-old female with no prior significant medical history presenting with an enlarging mass medial to her right lower eyelid for 2 years. Computed tomography scan showed nodular soft tissue in the middle part of the right nasolacrimal duct. Following complete excision of the cyst, histopathology reported an apocrine hidrocystoma, which is very rare.
