Only 10% of total synovial sarcomas present with an intraarticular location. We report a case of intraarticular synovial sarcoma in the right knee of a 25 years old male. Microscopically, the predominant monophasic fusocellular pattern of the neoplasm is another relevant points of this presentation.
CT scan and magnetic resonance showed a mass adjacent to femoral condyle, with a well delimited although festooned contour.
Grossly, the tumor was 5x4x3 cm. size and had an irregular contour with a polilobated and something villous articular. Microscopic sections revelled a dense proliferation of fusiform cells arranged in a lightly fasciculated pattern with other more loosely cellular areas and others high vascularized. Neoplastic cells showed a strong positivity to Vimentin, bcl2, EMA and PCNA.
Synovial sarcoma is a neoplasm of adolescents and young adults between 15 and 35 years old. Usually is found in extremities, in vicinity of the articulations, mainly the knee and in close relation with tendon sheaths and bursas. Differential diagnosis include nodular and localized synovitis, pigmented villonodular synovitis and synovial chondromatosis.
