Ultrasonography, mammography, and histopathological examination of male breast adenoid cystic carcinoma. (A) Ultrasonography revealed an irregular, mixed echoic, partial compressible mass in the subareolar region. (B) Mammography (mediolateral oblique) revealed a spiculate hyperdense lesion. (C) Microscopic picture of male ACC stained by H&E stain (original magnification × 50) shows a predominant cribriform pattern and is composed of pseudocysts, filled with basophilic mucin, surrounded by basaloid cells. Neoplastic cells were arranged in cribriform and tubular.
