Proliferating trichilemmal tumor (PTT) is an uncommon lesion that typically occurs on the scalp of older women. The risk factors which have been incriminated in the appearance of tumors of the scalp are: chronic sun exposure, the presence of sebaceous nevi, a history of ionizing radiation, burns, trauma or surgery of the scalp. CT can confirm the cystic and tissue nature of the lesion with the presence of calcifications, signs of locoregional invasion. The diagnosis of certainty is based on the anatomopathological study. The principle of treatment of TTP without the metastasis is a wide surgical excision with a margin of 1 cm in normal tissue. Endocranial extension and distant metastases are obstacles to surgical treatment. We report a rare case of scalp tumors in a hospital setting in a 75-year-old woman.
