Fibrosarcoma of the thigh. Case report and literature review.

Sarcomas of the soft tissue constitute a fairly rare group of neoplasms localized mainly at the level of the extremities. Apart from clinical and semeiotic investigations, diagnosis is based on imaging techniques. Among these (ultrasound, CT, NMR and angiography), all of which are helpful in diagnosis, NMR seems to provide the most complete data and sensitivity and specificity. In fact, it has greater specificity than ultrasound or CT as regards identification of any infiltration of the muscle or deep interstitial tissues and can also contribute information on the nature of the sarcoma, as it provides high definition of the structural composition of the tissues. Angiography remains important as a preoperative guide to the surgical approach. Surgery is the treatment of choice, although in recent years it has been integrated with radio or chemotherapy. Thanks to the progress in treatment constituted by combination treatments there has been a dramatic reduction in the need for amputations, compartmental excision and disinsertion of muscle groups. We report the case of a patient with fibrosarcoma of the thigh and discuss the various imaging techniques and different approaches to the treatment of these neoplasms.
