Invasive solid papillary carcinoma of breast mimicking as a benign condition: Rare case report

Abstract

Invasive papillary carcinomas of breast are rare tumors. They account for approximately 0.5% of all Invasive breast carcinomas. Invasive papillary carcinomas are commonly present in post-menopause women. These tumors lack the myoepithelial cell layer (MCL) within the papillae or at the periphery of the tumor. The diagnosis is difficult due to different clinical and radiological features. Immunohistochemistry (IHC) is really essential to confirming the diagnosis. We are here presenting one index case of a rare variety of invasive papillary carcinoma of the left breast. We present a case of invasive papillary carcinoma of the left breast in a 55-year-old female presented with a retroareolar lump without nipple discharge. Preoperative core biopsy showed fibroadenoma with a papillary configuration.But post-operative histopathological examination revealed it was an invasive papillary carcinoma. Invasive papillary carcinoma of breast even though a rare entity, making a diagnosis is very challenging. Thorough preoperative clinical and radiological examination should be done, so that timely management as well as proper treatment is possible.
