Multiple Eccrine Hidrocystomas of Scalp

Abstract

Hidrocystomas are rare benign cystic tumours that arise from the sweat glands (eccrine or apocrine). Eccrine hidrocystomas predominantly occur on the face as asymptomatic, skin-colored lesions with a chronic course and seasonal variability. They are more prevalent in females between the age of 30-70 years. Although rare and asymptomatic, they can be cosmetically disfiguring. Diagnosis can be made by histopathological examination, which reveals a unilocular cyst, with cystic cavity lined by one or two layers of cuboidal cells. Treatment options include medical, surgical and laser therapy. Here, we report a rare presentation of multiple eccrine hidrocystomas over the scalp.
