An adenomyoepithelioma of the breast is a rare tumour in the breast composed of glandular elements (adeno-) and myoepithelial cells. It is usually benign; however, there are reports of malignant behaviour. The histomorphologic appearance can mimic invasive ductal carcinoma, the most common type of invasive breast cancer.
