INTRODUCTION AND IMPORTANCESynovial Sarcoma is an intriguing disease, it represents a distinctive subtype of soft tissue sarcoma that does not exceed 10 % of all STS. This tumor can arise from the abdominal wall in very rare cases. Due to its unique presentation (occurring at a young age, various anatomical locations, and slow evolutionary kinetics), diagnosis can be challenging. The mainstay of treatment remains wide surgical excision with negative margins. CASE PRESENTATIONWe herein report a challenging diagnosis of synovial sarcoma with exceptional location, presented as a slowly evolving abdominal mass of the right iliac fossa. Soft tissue MRI confirmed the presence of a sub cutaneous mass without signs of local invasion. Surgical management as indicated. Anatomopathological findings were in favor of a synovial sarcoma of the abdominal wall. The patient was discharged. No complication was observed after 3 months follow up. CLINICAL DISCUSSIONPatients with synovial sarcoma of the abdominal wall is a very rare entity, therefor positive pre operative diagnosis is hard to achieve, because of the lack of specific clinical and radiological signs. No standard treatment is advised, beside surgical management wish is the main course of management. CONCLUSIONSynovial sarcoma is an infrequent pathology, with no specific signs in both clinical and radiological findings. The main course of management is surgery with healthy resection margins. Long term follow up is advised because of the high risk of recurrence.
