A Rare Case of Breast Carcinoma: An Entity Posing Cytological Challenge

Fine needle aspiration cytology (FNAC) is an important and primary screening tool for all breast lumps with high level of sensitivity and specificity. Diagnosing the rare breast carcinoma on FNAC is very challenging on account of various mimickers of the same. We hereby describe a rare case of breast carcinoma diagnosed on FNAC in a 34-year-old female confirmed on histopathology and immunohistochemistry (IHC). Preoperative diagnosis of apocrine carcinoma on FNAC and later confirmation on histopathology along with IHC study gives better insight to the cytopathologist and helps in better management protocol of the patient.
