Abstract

In females breast carcinoma is the most common cancer worldwide. Globally, 2.3 million women were diagnosed and 685 000 deaths due to breast cancer were reported in year 2020. Even in the era of immunohistochemistry (IHC) and molecular studies, the aggressive nature of the breast cancer can be determined by its histological type, grade, nodal status, and metastasis. Mucinous carcinoma (MC) is a rare variant of invasive breast cancer accounting for 1-7%. It is represented by the presence of large extracellular mucin pools. Based on the mucin content two main subtypes are identified: Pure Mucinous Carcinoma (PMC) and Mixed Mucinous Carcinoma (MMC). Pure Mucinous Carcinoma (PMC) is localized in most of the cases, whereas the mixed forms tend to metastasize to lymph nodes. Hence the mixed forms often require an axillary dissection during surgery. We are presenting a case of 70 year old female who presented with the complaints of lump in the right breast since 2 months and on ultrasound work up a score of BIRADS V was given. She underwent right modified mastectomy with right axillary dissection and was diagnosed as mixed type of mucinous adenocarcinoma breast by histopathological examination. It was confirmed by IHC which showed positivity for ER, PR & Synaptophysin and negativity for Her2neu. Prognostically MC is better compared to other variants of invasive ductal carcinoma as they respond to hormone therapy.
