Adenomyoepitheliomas are uncommon breast tumours. By definition they have a prominent component of myoepithelial cells, in addition to glandular elements lined by epithelial cells. Malignant adenomyoepithelioma of the breast is even more rare, characterised by malignant proliferation of epithelial and myoepithelial cells that show characteristic histological and immunohistochemical features. Only 11 cases have been reported to date. A case of malignant adenomyoepithelioma of the breast is reported.

In canine mammary neoplasms, greater inflammation is associated with higher histological grade, lymphatic invasion, and metastases. This retrospective study assessed the density of peri- and intratumoral tumor-infiltrating lymphocytes (TILs), tumor-associated neutrophils (TANs), and CD3 and CD79 lymphocytes in canine mammary neoplasms with a solid arrangement, and associated such data with histological types, immunophenotype, prognostic factors, cyclooxygenase-2 (Cox-2) expression and overall and cancer-specific survival. Sixty-one neoplasms with a solid arrangement were classified as malignant myoepitheliomas (6/9.

Adenomyoepithelioma (AME) is a rare variant of breast neoplasm. It is a biphasic tumour characterized by small epithelial-lined spaces with inner luminal cells and outer of abluminal (myoepithelial) cells. Either - or both - of these two cells may rarely undergo malignant transformation.

Adenomyoepithelioma (AME) is an uncommon breast tumor distinguished by the presence of both epithelial and myoepithelial cell proliferation. It often presents clinically as a well-circumscribed, non-painful mass, although it can also be asymptomatic and discovered incidentally during imaging. This case report describes a 32-year-old woman with a tumor that progressively increased in size.
