摘　　要：目的探讨浸润性乳头状癌的临床和病理学特征。方法复习1990年—2005年收治的128例原发性乳腺癌病理切片。其中,5例浸润性乳腺癌患者有单纯或部分微乳头成分。分析各种指标,包括发病年龄、肿瘤大小、组织学分级、淋巴管浸润和腋窝淋巴结状况。结果患者的发病年龄为35-62岁(平均51.4岁)。肿瘤大小2.0—4.0cm(平均2.9cm)。5例均有淋巴管浸润及腋窝淋巴结转移,且在术后5年内死于乳腺癌。结论浸润性微乳头状癌是一种预后差,淋巴结转移率高的乳腺癌,应对其鉴别诊断予以高度重视。Objective To study the clinical and pathologic features of invasive micropapillary careinoma（IMC）. Methods We reviewed all 128 cases of primary breast carcinoma that were surgically resected at our hospital between 1990 and 2005. Of these, 5 eases of invasive ductal carcinoma of the breast with a pure or partial micropapillary component were reported. The eases were analyzed using various parameters, including age at presentation, tumor size, tumor grade, presence of lymphatic invasion, and axially lymph node status. Results The patients＇ age at presentation ranged from 35 to 62 years （mean 51.4 years）. Tumor size ranged from 2.0 to 4.0cm （mean 2.9 cm）. AH of the cases had lymphatic invasion and positive lymph nodes. All of these 5 patients died from breast carcinoma within 5 years. Conclusions IMC is a special kind of infiltrating breast cancer with poor prognosis and high incidence of lymph node metastases.
