The clinicopathologic features of 2 new and 24 previously reported cases of pleomorphic adenoma of the breast are reviewed. This benign breast tumor resembles its salivary gland counterpart histologically. The circumscription and preferential juxta-areolar location suggest large breast duct origin of the tumors. Inappropriate surgery, i.e., mastectomy, was performed in 42% of the cases. Misdiagnosis and the resulting inappropriate treatment can easily be avoided if the pathologist includes this entity in the differential diagnosis when confronted with unusual differentiated epithelial breast lesions.
回顾了2例新的以及24例先前报道的乳腺多形性腺瘤的临床病理特征。这种乳腺良性肿瘤在组织学上类似于其涎腺对应物。肿瘤的边界及乳晕旁优先定位提示其起源于大乳腺导管。42%的病例接受了不恰当的手术，即乳房切除术。如果病理学家在面对不寻常的分化型乳腺上皮病变时，将该实体纳入鉴别诊断，误诊及由此导致的不恰当治疗很容易避免。
