objective:to analyze the difference between mammary duct ectasiaand plasma cell mammitis.methods:the data of 24 cases of mde and 28 cases of pcm,including clinical manifestations,distinguished diagnoses,surgical therapy,pathological results,were analyzed.results:the clinical manifestations of mde are nipple discharge and breast mass,which should be distinguished with breast mass and early stage of breast cancer.the treatment is local resection.major pathological changes are duct ectasia and obvious periductal inflammatory changes.the clinical manifestations of pcm are breast mass and inflammatory changes,which should to be distinguished with advanced breast cancer and inflammatory breast cancer.the surgical treatment is extensive resection.the major pathological changes are inflammatory reaction and multiple abscesses in breast tissue.conclusion:mde and pcm are significant different,and they are different progressing stage of disease,thus the two diagnoses are independent.

目的：分析乳腺导管扩张症和浆细胞性乳腺炎临床上的差异。提出各自独立诊断的论据。方法：结合24例乳腺导管扩张症和28例浆细胞性乳腺炎对两病的临床症状、鉴别诊断、手术治疗、病理结果进行比较分析。结果：乳腺导管扩张症临床表现为乳头溢液和乳腺肿物，主要与乳腺肿物和早期乳腺癌鉴别诊断，手术以局部切除多见，病理表现为导管扩张及导管周围明显炎性改变。浆细胞性乳腺炎临床表现为乳腺肿物和炎性改变，主要与晚期乳腺癌和炎性乳腺癌鉴别诊断，手术切除的范围较大，病理变化以乳腺组织的炎性反应和多发性脓肿为主。结论：乳腺导管扩张症和浆细胞性乳腺炎有明显的差异，应作为这两种疾病独立诊断。
