A Case of Cystic Clear Cell Hidradenoma / 대한피부과학회지

ABSTRACT

Clear cell hidradenoma (CCH) is a relatively rare benign tumor that shows differentiation toward the structure of an eccrine sweat gland. The tumor masses are composed of solid areas and tubular lamina. Cystic spaces are often present and on rare occasions they can be of considerable size. The cystic variant of CCH is referred as solid cystic hidradenoma. We present a case of cystic clear cell hidradenoma that occurred on the abdomen in a 42-year-old man. The tumor contained a solid tumor of CCH encircled by a large cystic space, and the cystic space was lined by two to four layers of epithelium.
