Abstract
Pilomatrical carcinoma is a rare, locally aggressive malignancy of follicular matrix origin. It presents as a rapidly growing, flesh-colored, or blueish, exophytic nodule with tumor asymmetry and poor circumscription. Histological features of these tumors include dominant hyperchromatic basaloid cells with high mitotic rate and nuclear pleomorphism; along with anucleate matrical cells and central necrosis. Pilomatrical carcinomas demonstrate a high rate of recurrence and tendency to metastasize. The most described treatment is wide excision of the tumor with negative margins with or without adjuvant radiation therapy. We present the case of a 70-year-old female patient who presented to the office with a 3-year history of a growing, exophytic lesion on the right nasal ala. A biopsy of the lesion was obtained, and histologic examination was consistent with a diagnosis of pilomatrical carcinoma.
