Giant trichilemmal cyst on gluteal region

Abstract

Proliferating trichilemmal tumor (PTT) is typically seen in middle aged or elderly patients, with a strong predilection for women and is usually situated in scalp. We are reporting such a tumor located on the gluteal region of a 52-year-old male. The tumor was diagnosed as PTT based on its specific histological features. The case is unusual because of sex of the patient and the tumor location. Moreover, this report illustrates a rare tumor which can be diagnostically challenging. The differentiation between a benign or malignant process in these lesions can sometimes be difficult. Careful clinical and histological assessment is necessary for an accurate diagnosis.
