Between 1988 and 1994, 78 cases (183 tendons) of flexor tendon injuries of the hand were repaired by microsurgical techique. The patients were followed up from4 to 6 months. The results were assessed according to the grading method of TAM. In 36 cases, 78 tendons were repaired by microsurgical suture and the excellentgood rate reached 76.2 per cent and the other 42 cases, 105 tendons were repaired with biological memberane wrapped arround the anastomotic site following microsurgical suture, in which, 32 cases, 77 tendons were followed up and the excellentgood rate was 89.5 per cent. The curative effect between the two groups hadsignificant difference statistically (Plt;0.05). Those cases with a bad results were mainly those injuries occurred in Zone II which had very poor soft tissue condition of the palm and thoes old cases having extensive scar tissue formation surrounding the tendon bed.
目的 探讨乳腺脂肪肉瘤的临床病理特点及鉴别诊断。 方法 分析2010年3月收治的1例乳腺多形性脂肪肉瘤的临床表现、组织病理学特征及免疫表型特点，并复习相关文献。 结果 肿瘤由高级别多形性肉瘤和数量不等的多形性脂肪母细胞组成。免疫组织化学：肿瘤细胞呈S-100蛋白阳性表达、CD34灶性阳性表达，细胞角蛋白、上皮膜抗原、巨噬细胞表面抗原、结蛋白、平滑肌肌动蛋白、肌调节蛋白、肌浆蛋白、CD31均呈阴性表达。结论 乳腺脂肪肉瘤是一种少见的原发于乳腺的间叶源性肿瘤，诊断上应首先排除乳腺化生性癌和恶性叶状肿瘤伴脂肪肉瘤分化，应依据形态学特点和免疫组织化学结果进行鉴别。
