Primary cutaneous metaplastic carcinoma is an uncommon cutaneous malignancy comprising a mixture of epithelial and mesenchymal components. The former is most frequently a squamous cell or basal cell carcinoma, and the latter is most typically a pleomorphic sarcoma or atypical fibroxanthoma. We describe the first primary cutaneous metaplastic carcinoma with angiosarcoma as the mesenchymal component arising on the scalp of a 90-year-old woman.
