EC Clinical and Medical Case Reports

Synovial sarcomas are rare malignant tumors of soft tissues, primarily occurring in young adults. They can develop in any soft tissue of the body but are more commonly found in the extremities near a major joint (lower two-thirds of the lower limbs). Other, albeit rare, originating sites include the head and neck, paravertebral region, chest, and abdominal wall. These tumors exhibit slow progression, marked by a gradual increase in mass volume, and are often painless. Surgical treatment involves mass resection, sometimes necessitating amputation of the entire limb. Adjuvant chemotherapy and/or radiotherapy are necessary to reduce the risk of local or distant recurrence. The recurrence rate depends primarily on the histological type of the tumor. We present the case of a patient operated for synovial sarcoma, who came for magnetic resonance imaging (MRI) of the lower limb following the discovery of osteocondensation in the femoral stump (operative site) on standard X-ray during postoperative surveillance.
