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

INTRODUCTION Rarely, the dermatologistmay encounter a primary cutaneous pleomorphic sarcoma (also known as a malignant fibrous histiocytoma), an undifferentiated neoplasm thought to be of mesenchymal origin. 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 sarcomawithmultiple 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.
