Pigmented malignant pilomatrixoma: report of a case and review of the literature

J Cutan Pathol. 1992 Jun;19(3):240-6. doi: 10.1111/j.1600-0560.1992.tb01669.x.

Abstract

An unusual variant of malignant pilomatrixoma displaying melanization of epithelial elements is described. Melanization is a rare event even in the benign form of this adnexal neoplasm. Previously reported cases of malignant pilomatrixoma are reviewed; none containing pigment have been previously reported to our knowledge. Possible etiologies for lack of pigment in most benign and malignant pilomatrixoma are discussed.
