Adenomyoepithelial adenosis mimicking phylloides: A diagnostic dilemma

Indian J Pathol Microbiol. 2024 Jan-Mar;67(1):223-225. doi: 10.4103/ijpm.ijpm_925_22.

Abstract

Benign proliferative breast diseases are well recognized in young females. Benign biphasic proliferation of epithelial and myoepithelial cells has been observed, among which adeno-myoepithelial adenosis is one of the rare morphologies published in the literature with the tendency to recur and poses a risk for low-grade malignant transformation. Here, we report a case of a young female who had a history of recurrent breast lump mimicking phyllodes tumor and eventually diagnosed as adeno-myoepithelial adenosis on histopathological examination.
