Core Tip

Core Tip: This report describes malignant adenomyoepithelioma (AME) of the breast, a rare tumor, which is difficult to assess and prone to local relapse and metastasis. No mature clinical experiences are available for reference, and it is thus significant to report unusual cases to help scholars worldwide establish a systematic treatment regimen. We present the treatment process and disease characteristics of two patients in different departments, as well as a brief literature review to investigate the clinicopathological features, diagnosis, treatment, and prognosis of malignant breast AME.
