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