Bilateral multicentric encapsulated papillary carcinoma of the breast: A rare case report

Abstract

Intraductal papillary carcinomas of the breast account for 2% of all breast cancers. Most occur during the fifth and sixth decades of life. Although they are considered in situ carcinomas, debate and uncertainty still exist regarding their true nature, because immunohistochemistry for myoepithelial cells has shown absence of myoepithelial cell layer along the epithelial-stromal interface of the tumor in many cases. Clinically, these tumors present as a palpable, centrally located mass or can be multifocal or present as bloody nipple discharge. Here is reported a rare case of bilateral multicentric encapsulated papillary carcinoma of the breast in a 45 year old female who presented with a two year history of lumps in both the breasts.
