Soft tissue sarcomas are rare mesenchymal cancers that pose a treatment challenge. Although small superficial soft tissue sarcomas can be managed by surgery alone, adjuvant radiotherapy in addition to limb-sparing…
Dermatofibrosarcoma protuberans (DFSP) is a rare dermal soft tissue sarcoma characterized by a typically indolent clinical course. The greatest clinical challenge in management of DFSP is achieving local control. There…
Malignant peripheral nerve sheath tumor (MPNST) is the sixth most common type of soft tissue sarcoma. Most MPNSTs arise in association with a peripheral nerve or preexisting neurofibroma. Neurofibromatosis type…
Myxofibrosarcoma is a unique subtype of soft tissue sarcoma with a locally infiltrative behavior. High-quality MRI imaging is critical for preoperative planning. Wide surgical resection with a 2 cm soft…
