Pilomatrix carcinoma: a case report and review of the literature.

Abstract

Pilomatrix carcinomas are malignant uncommon tumors of hair matrix origin. The clinicopathologic features of a case of pilomatrix carcinoma are described and compared with those of the previously reported cases. Because these tumors behave similarly to a basal cell carcinoma, a complete excision is necessary in order to minimize the likelihood of relapse.
