我院1982年12月至1987年11月间,手术切除子宫肌瘤标本2632例.属于特殊型平滑肌瘤110例,其中多细胞性105例,奇怪性2例,血管性1例,以及上皮样平滑肌瘤2例.本文对此110例特殊平滑肌瘤予以分析.大体标本注意观察了每个肌瘤假包膜清晰与否,肌瘤剖面时的手感(软与韧),及是否呈典型涡漩编织状、有无出血坏死区.多处取材行 HE 染色,必要时行特殊染色.镜下现察:多细胞性平滑肌瘤见平滑肌细胞排列密集,肌细胞浆相对减少,计算核分裂相,如5～10/10HP 属于潜在恶性,而>10/10HP 应诊为肉瘤,且应当与子宫内膜间质结节区相区别.血管平滑肌瘤可见血管壁的平滑肌细胞与肌瘤细胞之间有移行过渡.奇怪性平滑肌瘤瘤细胞为多边形成圆形。细胞核大而浓染,至于上皮样平滑肌瘤(亦称透明平滑肌瘤),瘤细胞呈圆形或多角形,胞浆丰富,有不等量嗜酸颗粒,核周可见透明晕.
In our hospital from December 1982 to November 1987, 2632 cases of uterine fibroids were resected.It belongs to 110 cases of special leiomyoma, including 105 cases of multicellular, 2 cases of strange, 1 case of vascular and epithelial Like leiomyoma in 2 cases.In this paper, 110 cases of special leiomyoma be analyzed.Most specimens observed each pseudosmetic fibroids clear or not, the fibroid section of the hand feel (soft and tough), and whether it was Typical swirling knit, with or without hemorrhage and necrosis area.Human samples were taken HE staining, if necessary, underwent special staining.Can observed under the microscope: smooth muscle cells of smooth muscle cells arranged in dense, relatively reduced muscle cell plasma, the calculation of mitotic Phase, such as 5 ~ 10 / 10HP is potentially malignant, and> 10 / 10HP should be diagnosed as sarcoma, and endometrial stromal and nodular areas should be differentiated.Vascular smooth muscle tumor visible vascular smooth muscle cells and fibroids Between transitional transitional weird leiomyoma tumor cells polygons round. The nucleus large and thick dye, as epithelioid leiomyoma (also known as leiomyoma), tumor cells were round or polygonal, abundant cytoplasm, ranging from eosinophilic particles, the nucleus visible transparent halo.
