Pleomorphic soft tissue sarcoma metastatic to the skin of the scalp and groin

Rarely, the dermatologist may encounter a primary cutaneous pleomorphic sarcoma (also known as a malignant fibrous histiocytoma), an undifferentiated neoplasm thought to be of mesenchymal origin.1 These uncommon skin tumors typically manifest as tender subcutaneous nodules. In contrast to primary cutaneous sarcomas, we present a case of a soft tissue pleomorphic sarcoma with multiple metastases to the cutaneous scalp and the groin. Although previous reports have described leiomyosarcoma metastatic to the skin, no report to our knowledge has detailed a widely metastatic undifferentiated sarcoma with lesions in multiple skin sites.
