Abstract:
BACKGROUND: Adenomyoepithelioma (AME) of the breast is a biphasic very uncommon tumour with epithelial/ my-oepithelial components. It can be easily recognised in an excised lesion, but it is more difficult to make a definitive diagnosis with needle biopsy. CASE REPORT: We report the case of a 42-year-old woman who presented with a mass in her right breast. The patient underwent a fine needle aspiration, and a diagnosis of C5 carcinoma was made. Neoadjuvant treatment was proposed to the patient but she refused and was referred to a third level centre where a needle core biopsy was performed and a diagnosis suggestive of AME was made. CONCLUSION: If there is cytological atypia, AME may be confused with infiltrating ductal carcinoma in needle biopsies because of limited tissue sampling.
