摘　　要：目的:探讨乳腺错构瘤的病理及影像学特征。方法:对11例乳腺错构瘤患者的临床特征、X线征象及病理表现进行回顾性分析。结果:患者平均年龄为46岁(26-58岁),10例可触及肿块(9例患者自己发现,1例体检摄片时发现),还有1例未能触及肿块。左乳7例,右乳4例,5/11(45.5%)肿块位于外上象限。11例钼靶X线平片均发现乳腺肿块,多数肿块呈卵圆形,边界清楚。肿块平均最大直径为6.0cm(2.5-13.0cm),6/11(54.5%)肿块呈混合密度影。4/11例(36.4%)术前X线确诊。镜下:肿瘤由数量不等、杂乱无章的乳腺导管、小叶和成熟的脂肪细胞及纤维组织混杂组成。结论:混合密度影是其特异性X线表现,不同个体肿瘤各成分比例的不同导致X线表现差异较大。Objeetive： To study the clinical, mammographic and pathological features of the mammary hamartoma. Methods： The clinical materials, mammographic and histological feature of 11 cases with mammary hamartoma were analyzed retrospectively. Results： The mean age was 46 years （range 26-58 years）. Hamartomas were clinically identified as a palpable lump in 10 cases （9 were detected by the patient and 1 by a physician）. The other 1 hamartoma was not palpable. 7 lesions were in the left breast and 4 were in the right breast; 45.5% were located in the upper outer quadrant. All 11 hamartomas were recognized at mammography, most hamartomas were ovoid, and the lesions were well circumscribed. The mean greatest diameter was 6.0cm （range 2.5-13.0 cm）. 6/11 （54.5%） mass have mixed density. The coincident rate was 36.4% before operation. Histological study showed that these tumors are composed of a variable amount of fat, fibrous tissue, and epithelial component. Conclusions： Mixed-density X-ray is its specific performance, and the proportion of tumor components played an important role on the X-ray manifestations of mammary hamartoma.
