In a 2003 review of salivary gland-like tumors of the breast, several lesions were described, including pleomorphic adenoma, adenoid cystic carcinoma, benign and malignant myoepitheliomas, syringomatous carcinoma, adenomyoepithelioma
, acinic cell carcinoma, oncocytic carcinoma, and mucoepidermoid carcinoma (1).
Adenomyoepithelioma (AME), a biphasic neoplastic proliferation of luminal and myoepithelial cells, was first described by Hamperl (1) in 1970.
9,29,30) A myoepithelial carcinoma arising in an adenomyoepithelioma with a high Ki-67 labeling index in myoepithelial cells has been reported.
Myoepithelial lesions of the breast: myoepitheliosis, adenomyoepithelioma, and myoepithelial carcinoma.
Atypical adenomyoepithelioma of the breast: diagnostic problems and practical approaches in core needle biopsy.
Hemotoxylin-eosin, S100, and MA903 histologic stains identified myoepithelial nuclear and cytoplasmic elements consistent with adenomyoepithelioma (Figure 3).
We present the first published case of a lesion containing adenomyoepithelioma imaged with photon-counting digital mammography.
Adenomyoepithelioma is a rare myoepithelial breast lesion, with only 150 cases documented in the literature.
Biphasic lesions with a predominant spindle cell component and a benign epithelial (ductal) component, such as fibroadenomas, phyllodes tumors, pseudoangiomatous stromal hyperplasia, and adenomyoepithelioma
A number of breast tumors manifest true myoepithelial differentiation, including adenomyoepithelioma
and myoepithelioma, as well as the salivary glandlike tumors such as adenoid cystic carcinoma.
We found three adenomyoepitheliomas
, a rare lesion in the DMBA model, exclusively in mammary cancer cohort mice perinatally exposed to TCDD and fed HFD (Figure 2B).
unpublished data, 2006), and adenomyoepitheliomas
, also display a basal-like phenotype.
