A 71-year-old slender, previously healthy man was admitted to the authors' institution because of a huge painless mass in his left scapular area. Physical examination revealed a second soft tissue mass in his right scapular region and a third soft tissue mass in the anterior side of his right shoulder. Surgical treatment including marginal resection of the second and third small masses followed by wide local resection of the huge tumor was performed. Histologic examination showed that the first mass was a well differentiated lipomalike liposarcoma, whereas the second and third lesions were identified as intramuscular lipomas. A review of the literature showed two cases of retroperitoneal liposarcoma associated with multiple subcutaneous lipomas and two cases of liposarcoma involving an extremity associated with multiple subcutaneous lipomas. There is no previous report in which intramuscular liposarcoma was associated with multiple intramuscular lipomas.
一名71岁、身材苗条、既往健康的男性因左肩胛区出现巨大无痛性肿块入住作者所在机构。体格检查发现其右肩胛区有第二个软组织肿块，右肩前侧有第三个软组织肿块。进行了手术治疗，包括对第二个和第三个小肿块进行边缘切除，随后对巨大肿瘤进行广泛局部切除。组织学检查显示，第一个肿块是高分化脂肪瘤样脂肪肉瘤，而第二个和第三个病变被确定为肌内脂肪瘤。文献回顾显示，有两例腹膜后脂肪肉瘤合并多发皮下脂肪瘤，还有两例肢体脂肪肉瘤合并多发皮下脂肪瘤。此前尚无肌内脂肪肉瘤合并多发肌内脂肪瘤的报道。
