Multiple Eccrine Hidrocystoma of the Face, Neck, Anterior Chest and Both Arms / 대한피부과학회지

ABSTRACT

Eccrine hidrocystomas are benign cystic dilatations with eccrine differentiation. The clinical presentation usually occurs as a solitary tense vesicle or translucent papule located predominantly on the face, whereas multiple eccrine hidrocystomas are unusual. Histologically, eccrine hidrocystoma consists of one or more partially collapsed unilocular cysts in the dermis, which show flattened epithelium that is partially lined by two layer of cuboidal epithelium. We report here on a case of the patient with multiple eccrine hidrocystomas that showed an especially generalized presentation that included the face, neck, anterior chest and both arms.
