Clear cell hidradenoma of the gluteal region: a case report.

ABSTRACT

Clear cell hidradenoma is a rare skin appendage tumor. A 41-year-old female presented with right gluteal mass. Excisional biopsy of the mass was performed. Under the epidermis, an eosinophilic-cytoplasm, uniform-appearance, oval-round-nucleus, benign tumor with cystic and solid components was detected. These results were consistent with clear cell hidradenoma. The patient had not been given postoperative adjuvant treatment and has been under follow up free from disease for 2 years.
