We report the case of a 63-year-old woman who presented with a right breast lump detected by screening mammography. The lesion was nonpalpable, and the ultrasonography revealed suspicious features. In contrast with imaging features, fine-needle aspiration cytology showed benign ductal cells arranged in groups, with fragments of hyalinized eosinophilic stroma, and round or bipolar bare nuclei in the background, findings consistent with a benign tumor. A core needle biopsy performed to rule out a breast cancer revealed an adenosis tumor of the breast.
