Overview

Background

Apocrine hidrocystomas are benign cystic proliferations of the apocrine secretory glands. Apocrine hidrocystomas most commonly appear as solitary, soft, dome-shaped, translucent papules or nodules and most frequently are located on the eyelids, especially the inner canthus. Apocrine hidrocystomas grow slowly and usually persist indefinitely.

Pathophysiology

Although the origin of apocrine hidrocystomas is not known entirely, they are believed to be adenomatous cystic proliferations of the apocrine glands. The exact stimulus for the development of an apocrine hidrocystoma is unknown. Plausible causes of the closely related eccrine hidrocystoma include occlusion or blockage of the sweat duct apparatus, which results in the retention of sweat and a dilated cystic structure.

Prognosis

Apocrine hidrocystomas grow gradually and persist indefinitely after attaining full size. They seldom recur after removal. Apocrine hidrocystomas are entirely benign. Cysts may annoy patients; however, symptoms usually are mild or absent. Vision usually is not affected.
