Abstract

Primary synovial sarcoma arising in the anterior abdominal wall is rare and is a rare extra-articular tumor site. It should be considered in the differential diagnosis of anterior abdominal wall masses. It is a rare malignant mesenchymal tumor. It commonly occurs in adults in the extremities in close association with joint capsule, tendon sheaths, bursae and fascial structures. Synovial sarcoma is derived from multipotent stem cells, which can differentiate into mesenchyma and epithelial structures. Three subtypes are described histologically -biphasic, monophasic, and poorly differentiated synovial sarcoma. We report a case of a 40-year-old male patient presented with swelling over the anterior abdominal wall on the right side in the lower abdomen for 1 month which was rapidly increasing in size. An ultrasound followed by computed tomography and magnetic resonance imaging of the abdomen were performed for knowing the extent of the tumor. Immunohistochemistry was suggestive of monophasic synovial sarcoma.
