A giant apocrine hidrocystoma of the trunk

“…To our knowledge, the only other reported apocrine hidrocystoma >3 cm in size was by Holder et al in 1971, who described a 7.0 x 5.0 cm apocrine hidrocystoma on the trunk [5]. Therefore, our report represents only the second case of a giant apocrine hidrocystoma on the trunk described.…”

Treatment of Multiple Apocrine Hidrocystomas with the Carbon Dioxide (CO2) Laser

“…It is typically an asymptomatic dome‐shaped cystic lesion, often translucent, and may vary in color from skin‐tone to blue‐black 2,3 . Most lesions are smaller than 15 mm, but larger giant apocrine hidrocystomas up to 7 cm in diameter have been reported 7,8 . The great majority of apocrine hidrocystomas occur on the head.…”
