Deciphering primary acinic cell carcinoma of the Breast: Insights from a comprehensive case series and Systematic review

Abstract

Primary acinic cell carcinoma (PACC) of the breast is a rare oncological entity that mimics acinar cell differentiation similar to that observed in salivary glands. This distinct subtype is characterized by low-grade malignancy and has only been documented in a limited number of cases. Despite its classification frequently as TNBC, PACC of the breast typically shows a comparatively favorable prognosis. Our study aims to enrich the current understanding of PACC through a comprehensive review of cases managed at our institution, analyzing their clinical, histopathological, and therapeutic profiles including chemotherapy and radiation therapy, and patient outcomes and allows us to compile a comprehensive dataset for in-depth analysis of treatment responses and long-term survival rates, contributing to a broader understanding of the disease’s natural history.
