title: Malignant pilar tumor of the scalp: a case report and review of literature.
abstract: Pilar tumor is a rare neoplasm arising from the external root sheath of the hair follicle and is most commonly observed on the scalp. These tumors are largely benign, often cystic, and are characterized by trichilemmal keratinization. Wide local excision has been the standard treatment. Recent reports have described a rare malignant variant with an aggressive clinical course and a propensity for nodal and distant metastases which, therefore, merits aggressive treatment. In this report, we present a case of malignant pilar tumor of the scalp with multiple nodal metastases at presentation. Diagnostic and therapeutic considerations, in the form of adjuvant radiotherapy, are subsequently discussed.
