title: Malignant cutaneous mixed tumor. A new case with unusual clinical features.
abstract: We report the case of an ulcerated malignant cutaneous mixed tumor occurring on the nose of a 75-year-old woman. Malignant cutaneous mixed tumor (CMT) is a rare neoplasm. Of the 14 previously reported cases, 10 occurred on the extremities, three on the trunk, and one on the scalp. This contrasts with the benign CMT which is found mainly on the head and neck region, the nose being the most commonly affected site. Although eight of the cases of malignant CMT recurred and 10 metastasized, the primary lesion never ulcerated.
