Abstract
In this series of case reports, we present two women diagnosed with rare cancer, adenoid cystic carcinoma (ACC) of the breast. Though this neoplasm has a relatively favorable prognosis, more information regarding its pathophysiology, response to variable treatments, and long-term prognosis is needed. The objective of our case series is to present the medical decisions and clinical courses of a 50-year-old female and a 79-year-old female with ACC of the breast. Through ongoing shared knowledge from cases like ours and further experimental research, a more reliable diagnostic and treatment algorithm can be substantiated.
