Retroperitoneal liposarcomas are rare tumors arising from the soft tissue of the retroperitoneum and are of mesenchymal cell origin. They can reach a large size prior to causing symptoms and generally have a poor prognosis. We present the case of a 93-year-old lady presenting with a large retroperitoneal liposarcoma at the site of a previous colonic anastomosis for the adenocarcinoma treatment. It caused minimal symptoms initially, but surgical resection was undertaken when the tumor was found to be growing significantly in size. However, due to the tumor's location and its invasion into surrounding structures, the resection was not feasible and subsequently abandoned. A retroperitoneal liposarcoma arising from the site of a previous colonic resection has not been previously described. A review of the diagnosis and current management of these lesions is also given.
腹膜后脂肪肉瘤是一种起源于腹膜后软组织的罕见肿瘤，来源于间充质细胞。它们在引起症状之前可以长得很大，总体预后较差。我们报告一例93岁女性病例，其在先前因腺癌治疗而行结肠吻合术的部位出现巨大腹膜后脂肪肉瘤。该肿瘤最初引起的症状轻微，但在发现肿瘤体积显著增大后进行了手术切除。然而，由于肿瘤的位置及其对周围结构的侵犯，切除不可行，随后放弃。先前未曾描述过起源于既往结肠切除部位的腹膜后脂肪肉瘤。本文还对这些病变的诊断和当前治疗进行了综述。
