Breast Adenomyoepithelioma: Ultrasonography, Elastography, Digital Mammography, Contrast-Enhanced Digital Mammography, and Pathology Findings of This Rare Type of Breast Tumor.

Breast adenomyoepithelioma is considered as an uncommon breast tumor. It is evaluated as a variant of intraductal papilloma. The treatment of choice is local resection with free margins. It is the first case of breast adenomyoepithelioma reported with conventional ultrasonography, elastography (both free-hand and acoustic radiation force impulse imaging), digital mammography, contrast-enhanced digital mammography, and pathology findings. A 35-year-old white woman presented with a painless lump of the left breast. Treatment was local resection with free margins. There has been no recurrence for 6 months. Although breast adenomyoepithelioma is an uncommon breast tumor, its awareness is imperative because the differential diagnosis from other breast tumors is quite extensive.
