Abstract
Primary carcinosarcoma is a very rare neoplasm comprising two intermingling malignant components—epithelial and mesenchymal. The authors report a new case of primary cutaneous carcinosarcoma involving the helix of the ear. Immunohistochemical analysis revealed epithelial components of both basal cell and squamous cell carcinomas with a partially ossified sarcomatous-like component.
