Proliferating Trichilemmal Tumor (PTT) is an uncommon append age al skin tumor that affects mainly elderly women. It originates from the external root sheath of the hair follicle and most commonly observes on the scalp with pathological abrupt keratinization without granular cell layer disturbance. Because of limited cases in the literature, the management of malignant PTT seems to be controversial. Although PTT mainly requires wide local excision, many other adjuvant modalities have been tried before. Here, we present a case of malignant PTT in a 42 years female patient who presented with scalp mass over the occipital region in the last four years.
