Unusual Case of Bilateral Breast Cancer: A Pure Encapsulated Papillary Breast Tumor of the Right Breast and a Contralateral Invasive Ductal Carcinoma

Background: Intracystic papillary breast cancer is a very rare tumor that occurs most frequently in elderly postmenopausal women. Aim: In this article we presented a case of a 66-year-old woman who underwent excisional biopsy due to a right breast mass. Case presentation: Histological examination revealed the “pure” encapsulated papillary breast carcinoma without coexisting in situ neoplasm and/or invasive carcinoma. This is a rare lesion of the breast that can clinically mimic breast benign mass with only local or regionally aggressive course. Conclusion: In order to avoid misdiagnosis, both the clinician and the breast radiologist should have the possibility of diagnosing this tumor. Intracystic papillary carcinoma of the breast associated with lymph node?metastasis has rarely been reported, but the sentinel lymph node biopsy may be prudent in such cases, despite the non aggressive behavior.

乳房皮肤凹陷与皮下脂肪柱放射病理的相关性研究

目的 研究基于乳腺X线摄片中乳腺无数个2～3mm大小X线透亮影的组织学基础。材料和方法本研究经机构审查委员会批准，并遵从HIPAA。对2例乳房切除手术标本被舍弃组织及2例乳房缩小成形术病人的被切下的皮肤进行精细的X线摄影，同时进行皮肤及皮下脂肪组织学检查。结果 比较组织学与X线检查的结果发现。乳房X线检查所见的透亮影是真皮层内面的皮肤凹陷嵌入皮下脂肪组织突出的脂肪柱。
