Clear‐Cell Hidradenoma of the Forearm in a Young Boy

Abstract

We treated a 5-year-old boy with clear-cell hidradenoma of the forearm. Our literature search found only one previous report of this disease occurring during the first decade of life, and the present patient is the first with involvement of the limbs. This presentation demonstrates that clear-cell hidradenoma needs to be considered in the differential diagnosis of cutaneous tumors even in young children, which is of interest because malignant transformation can occur.
