[A case of breast adenomyoepithelioma that was diagnosed by local excision].
A case is a 72-year-old woman with right breast lump detected by palpation. In the end of November 2009, we palpated a mass with clear boundaries in the right D area. Breast echography showed a nearly 3 cm tumor in the cyst. MRI showed an augmented effect of marginal irregular 3 cm in size. A diagnosis was adenomyoepithelioma by needle biopsy. We performed lumpectomy because a breast cancer was suspected. Histopathology findings were adenomyoepithelioma ER(+), PgR(-), HER2(0), α SMA(+). A diagnosis of adenomyoepithelioma is rather hard by means of imaging or biopsy. When this disorder was in doubt, a tissue analysis is indispensable for a determination of diagnosis because we were able to make a diagnosis by local excision without an excessive invasion. So we herein report our experience of adenomyoepithelioma with reference.
