The main locations of the liposarcoma, the most common of the soft tissue sarcomas, are the lower limbs and the retroperitoneal space. We report the case of a 58 year-old male patient presenting with a huge and painless mass of the left fossa ischiorectalis. Preoperative tests and CT-scan of the pelvis evoked the diagnosis of liposarcoma, laminating and lifting the rectum and bladder. Visceral walls were respected. The patient underwent a en-bloc excision of the tumour by a combined perineal and abdominal route. Pathological examination of the mass (1.7 kg) confirmed the diagnosis of well differentiated liposarcoma. No further treatment was initiated, but, because of the high risk of local recurrence, the patient has been placed under a close follow-up schedule.
脂肪肉瘤是最常见的软组织肉瘤，其主要发病部位是下肢和腹膜后间隙。我们报告一例58岁男性患者，其左坐骨直肠窝出现一个巨大且无痛性肿块。术前检查及骨盆CT扫描提示脂肪肉瘤的诊断，肿瘤包绕并抬高直肠和膀胱，未侵犯脏层壁。患者通过会阴联合腹部途径接受了肿瘤整块切除。对该1.7千克肿块的病理检查确诊为高分化脂肪肉瘤。未进行进一步治疗，但由于局部复发风险高，患者已被安排密切随访。
