Proliferating trichilemmal tumor (PTT) is a rare neoplasm that develops from cystic follicular lesions, whose histological characteristic is the presence of trichilemmal keratinization. The most common manifestation is a solitary lump on the scalp of older women. It describes a case of proliferating trichilemmal tumor, which presents as a cystic tumor lesion on the scalp of an older woman, with recurrence after removal without diagnostic investigation.
