Abstract:
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. We are presenting a case report of a 47-year-old patient with malignant trichoblastoma containing melanin deposits and propose to define this variety of the tumor as a separate entity: malignant melanocytic trichoblastoma.
