Abstract:
Trichilemmal carcinoma is a rare malignant neoplasm of hair follicle which is derived from or differentiates towards the outer root sheath. Despite the frequent presence of histologically malignant features, it has a relatively benign clinical behavior. We report a case of trichilemmal carcinoma in an 87-year-old woman who showed a solitary slightly tender, 1.5X2cm-sized, verrucous, erythematous nodule with crust on the vertex of scalp. In her past medical history, it had been excised at a private clinic without a histopathological evaluation and recurred 1 year later. Histopathologically, tumor cells showed PAS-positive cytoplasms and cytologic atypia with a few mitotic figures. The patient was treated with a wide surgical excision. She has had no evidence of recurrence or metastasis.
