Adenomyoepithelioma of the Breast with Hemorrhagic Change Diagnosed as Papilloma on Core Needle Biopsy: A Case Report

Abstract

Adenomyoepithelioma (AME) is a rare disease entity that represents biphasic proliferation of ductal epithelial and myoepithelial cells. AME can be confused with other neoplasms including malignancy because AME has various cytologic characteristics and nonspecific radiologic features. We describe an unusual AME with hemorrhagic change that was diagnosed as papilloma on core needle biopsy three times previously. The imaging features of AME are also discussed here.
