摘要

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.
