Liposarcomas correspond to the most common histological subtype of soft tissue sarcomas. They can be subdivided into: well differentiated or atypical lipoma, undifferentiated, myxoid, round, and pleomorphic cells. Atypical lipomas are the most prevalent and usually appear as asymptomatic softened tumors. They are locally aggressive but rarely lead to distant metastases. The diagnosis of this tumor is based on the imaging and histopathologic findings. Treatment consists of excision surgery with complete tumor removal. It has a good prognosis due to the low percentage of distant metastases. We report a rare case of giant atypical lipoma as well as the adopted therapy and evolution.
脂肪肉瘤是软组织肉瘤中最常见的组织学亚型。它们可分为：高分化或非典型脂肪瘤、未分化型、黏液型、圆形细胞型和多形性细胞型。非典型脂肪瘤最为常见，通常表现为无症状的软化肿瘤。它们具有局部侵袭性，但很少导致远处转移。该肿瘤的诊断基于影像学和组织病理学检查结果。治疗方法为切除手术，完整切除肿瘤。由于远处转移率低，其预后良好。我们报告了一例罕见的巨大非典型脂肪瘤病例以及所采用的治疗方法和病情进展。
