Bilateral Pleomorphic Ductal Carcinoma Of Breast- A Rare Presentation With Its Diagnostic Dilemma

Abstract

Pleomorphic carcinoma of breast is a rare morphological subtype of Invasive Breast Carcinoma No Special Type (IBC NST), which has histomorphological overlap with other entities. Here we present such a case with bilateral breast involvement in 45 years old nulliparous woman with family history of breast carcinoma. Typical numerous multinucleated cells (>50%) with marked pleomorphism and wide areas of necrosis were histopathological presentation. AE1/AE3 and Vimentin were positive. Ki-67 labelling index was high along with HER2 amplification. Important differentials were IBC NST with Osteoclast-like giant cells, Choriocarcinomatous pattern, metaplastic carcinoma & metastatic disease all of which was ruled out with proper clinical, histological & immunohistochemical approach. Despite the aggressive nature of the neoplasm and presence of adverse prognostic factors, this case responded well with adjuvant chemotherapeutic regimen.
