Abstract

The trichilemmic cyst (TC), also known as the hair cyst, is a rare adnexal tumor, developed from the isthmic portion of the hair follicle. More aggressive forms, such as proliferative trichilemmal tumors (PTT), and malignant proliferative trichilemmal tumors (MPTT) can occur, but they are much less common. PTT is generally benign, some cases with malignant transformation are described in the literature. Therefore the criteria of malignancy (clinical and histological) have been widely discussed. The real challenge is to distinguish the benign form from the malignant one.

Herein, we report the case of a 71-year-old patient who presented a scalp parietal tumor that had been evolving for 19 years, whose histological study was related to a proliferating trichilemic tumor, without sign of malignancy.
