Trichoblastoma is an uncommon benign cutaneous neoplasm of the hair germ cell. The pigmented variety of the tumor is rare. There have only been a few case reports describing the malignant counterpart of trichoblastoma. There are no reports describing a pigmented variety of malignant trichoblastoma.
