ABSTRACT
Malignant proliferating trichilemmal tumor (MPTT) is a rare cutaneous tumor predominantly affecting the scalp, eyelids, neck and face of elderly women. It is a large, solitary, multilobulated lesion that may arise within a pilar cyst. These tumors are largely benign, often cystic, and are characterized by trichilemmal keratinization. However, at times, the tumor has an aggressive clinical course and a propensity for nodal and distant metastases. Wide local excision with a 1 cm margin of normal tissue is the treatment of choice. Adjuvant chemotherapy and radiotherapy have been occasionally used to prevent recurrence in MPTT. This is a case report of a recurrent malignant trichilemmal tumor over scalp in a young female patient with nodal metastasis.
