Multimodal ultrasound for preoperative evaluation of dermatofibrosarcoma protuberans: A series of 40 cases

Dermatofbrosarcoma protuberans (DFSP) is a rare, low to intermediate-grade sarcoma, which needs imaging examination. Small series of ultrasound findings in DFSP have been published; however, the usefulness of elastography and contrast-enhanced ultrasound (CEUS) in DFSP has not been studied.
