An adenomyoepithelioma of the breast is a rare tumour in the breast composed of glandular elements (adeno-) and myoepithelial cells. (wikipedia.org)
In addition, a variety of other rare breast lesions reveals a papillary architecture such as tall cell carcinoma with reversed polarity (TCCRP) and mucinous cystadenocarcinoma, adenomyoepithelioma, and secretory carcinoma. (nih.gov)

Benign1
Adenomyoepithelioma is a benign well delineated/circumscribe single small (1 cm to 8 cm size), multi-nodular/lobulated, greyish-white firm mass/masses of rubbery consistency. (pathoclinics.com)
Myoepithelial5

Adenomyoepithelioma usually composed of many small round ovoid and tubular glands, lined by bland luminal and myoepithelial cells, later should be prominent and striking in appearance. (pathoclinics.com)
Myoepithelial markers are usually focally present and not extensive as seen in adenomyoepithelioma. (pathoclinics.com)
But, rest of the areas and high number of myoepithelial cells, highlighted by calponin and P63 favors adenomyoepithelioma. (pathoclinics.com)
Some features like circumscribed mass and lobules of marked proliferation of closely lacked regular round ducts and tubules with open lumina and very little stroma may resembles to tubular adenoma , but tubular adenoma usually lined by single layer of myoepithelial cells while adenomyoepithelioma (tubular variant) show prominent myoepithelial cells proliferation.

Pleomorphic adenoma1
Focal or rare presence of chondroid metaplasia resembles to salivary gland pleomorphic adenoma, considered as a variants of adenomyoepithelioma. (pathoclinics.com)
Adenoid cystic ca1
Adenoid cystic carcinoma can show areas of tubular component of adenomyoepithelioma and adjacent cribriform pattern. (pathoclinics.com)
Carcinoma1
Atypical features like high-grade nuclear atypia, increased mitotic activity (more than three mitosis per 10 HPF), and focally infiltrative margins should be considered strongly for carcinoma in a background of adenomyoepithelioma. (pathoclinics.com)
Tumor2
La localización del tumor primario fue diferente en ambos grupos, en el grupo A fue el cáncer de riñón y en el grupo B el cáncer de mama. (usal.es)
En otras ocasiones se presentan como un nódulo tiroideo años después del tumor primario, lo que condiciona el diagnóstico. (usal.es)
