Review of primary superficial soft tissue mesenchymal tumors of malignant or intermediate biological potential

AbstractThe majority of the sarcomas are deep in location, larger than 5  cm in size, and heterogenous in imaging appearance. However, when sarcomas occur superficially, these typical features may be absent, failing to alert the radiologist to a malignancy and mimicking one of the more numerous benign superficial tumors that make up the bulk of soft tissue mass evaluati ons. This manuscript will discuss the current role of imaging in recognizing features concerning for superficial soft tissue sarcomas. Provided is an overview of the demographic, clinical, and imaging features of the most commonly encountered superficial soft tissue sarcomas, including undifferentia ted pleomorphic, leiomyosarcoma, synovial sarcoma, liposarcoma, myxofibrosarcoma, dermatofibrosarcoma protuberans, epithelioid sarcoma, and angiosarcoma. A less common but primary superficial tumor, angiomatoid fibrous histiocytoma, is also reviewed as the diagnosis may be confounding both clinicall y and on imaging studies.
