title: Clear cell sarcoma of the tendinous portion of the quadriceps muscle at the knee joint managed by limb-sparing surgery.
abstract: A case report of clear cell sarcoma of the tendinous portion of the quadriceps in the knee joint of a 33-year-old female is presented. This insidious, usually painless malignant tumor is often misdiagnosed and may be referred to the sports medicine specialist as a sport-related injury. The duration of symptoms and the size of the lesion are important prognostic factors. Wide excision or radical surgery is necessary to cure such tumors. With improved reconstructive techniques, including free vascularized myocutaneous flaps, limb-sparing surgery is now possible.
