Synovial sarcoma (SS) usually affects joints, bursae, and tendons of extremities and is very infrequent in the head and neck, abdomen, thorax, prostate and kidney, skin, blood vessels, and nerves. Primary intra-abdominal SS is exceeding uncommon and has non-specific symptoms or compress surrounding structures. The diagnosis is a challenge, and histopathological and immunohistochemical studies must confirm the hypothesis. We report the case of SS that has origin in peritoneal structures and a longstanding unsuspected course. The patient was a 64-year-old woman who claimed chronic pain in the left iliac fossa, without additional symptoms. She related laparoscopic oophorectomy, cholecystectomy, and abdominal hysterectomy in the previous three decades. There was neither local invasion nor lymph nodal, vascular or neural invasion, and her surgical treatment by open abdominal procedure was uneventful. The herein reported case aims to enhance the index of suspicion.
滑膜肉瘤（SS）通常影响四肢的关节、滑囊和肌腱，在头颈部、腹部、胸部、前列腺和肾脏、皮肤、血管和神经中非常罕见。原发性腹腔内 SS 极为罕见，且具有非特异性症状或压迫周围结构。诊断具有挑战性，必须通过组织病理学和免疫组织化学研究来证实这一假设。我们报告了一例起源于腹膜结构且长期未被怀疑的 SS 病例。患者为 64 岁女性，诉左髂窝慢性疼痛，无其他症状。她在过去三十年中曾行腹腔镜卵巢切除术、胆囊切除术和腹式子宫切除术。未见局部侵犯、淋巴结、血管或神经侵犯，开放性腹部手术治疗过程顺利。本报告病例旨在提高对该病的警惕性。
