ABSTRACT

Introduction: Encapsulated papillary carcinoma (EPC) is a rare breast malignancy with a slow growth rate and excellent prognosis.
Case Series: There were two cases of EPC, one of them was a 60-year-old female presenting with two lumps in the right breast at 3 o‘clock and 9 o‘clock positions. A right modified radical mastectomy with axillary dissection was done subsequently. On histopathology EPC was diagnosed. The other case was of a 45-year-old female presenting with bloody nipple discharge and a 2-cm subareolar lump. Histopathology revealed features of EPC with invasion into the fibrous capsule. In both cases, there was no associated ductal carcinoma in situ (DCIS) in the surrounding tissue and lymph nodes were not involved.
Conclusion: Encapsulated papillary carcinoma is a rare breast malignancy with excellent prognosis. In the absence of associated DCIS in the surrounding tissue or areas of infiltrating carcinoma, it has a very favorable prognosis with adequate local therapy alone.

Keywords: Bloody nipple discharge, Cystic, Encapsulated papillary carcinoma breast
