1975年Enzinger和Harvey报导一类良性脂肪瘤性肿瘤,共114例,命名为梭形细胞脂肪瘤,组织学特征是成熟脂肪细胞与梭形成纤维细胞、胶元粘液性基质混杂组成。这种肿瘤容易误诊为脂肪肉瘤或其他良性、恶性肿瘤。1976年Angervaki等报导14例,最近日本学者Kitano亦报导12例。该瘤绝大多数在45岁以上发病,男性易患,一般发生于肩部和后颈部,无明显症状,肿瘤从拇指大至鸡蛋大,可移动,分界清楚。质地中等,灰黄或灰白色,部分区域可呈粘液变。组织学改变,成熟脂肪细胞被束状排列的梭形细胞分割,可呈小叶状。细胞学特点是:1、均是成熟单空泡状脂肪细胞,绝无多泡沫状脂 In 1975 Enzinger and Harvey reported a class of benign lipoma neoplasms, a total of 114 cases, named spindle cell lipoma, histologically characterized by mature adipocytes and shuttle-forming fibroblasts, colloidal mucin matrix. This tumor is easily misdiagnosed as liposarcoma or other benign or malignant tumors. In 1976, Angervaki et al. reported 14 cases. Recently, Japanese scholar Kitano also reported 12 cases. Most of the tumors are onset at 45 years of age and are susceptible to men. They usually occur in the shoulders and back of the neck and have no obvious symptoms. The tumors are large from the thumb to the big eggs, and they can be moved and the boundaries are clear. Medium texture, grayish yellow or grayish white, some areas can be mucus change. With histological changes, mature adipocytes are divided into bundles of spindle cells, which are lobulated. Cytological characteristics are: 1, are mature single vacuolar adipocytes, absolutely no more foamy lipids
