Invasive papillary carcinoma of the breast – A rare case report

Abstract

Invasive papillary carcinoma (IPC) of the breast is a rare entity, comprising approximately <1%–2% of all breast cancers. It is most commonly seen in postmenopausal females and rarely seen in males. IPC is arising from the dilated duct or large duct. They are low-grade tumors microscopically consisting of well-circumscribed solid nodules of the neoplastic cells separated by fibrovascular cores. It has excellent prognosis, so exact diagnosis is necessary. We report a case of a 68-year-old postmenopausal female, who came with complaints of a lump in the left breast for the past 2 months, modified radical mastectomy was done, and the specimen was sent for histopathological examination. Immunohistochemistry was done estrogen receptor and progesterone receptor positive with human epidermal growth factor receptor 2 negative. The case is presented due to its rarity.
