Benign adenomyoepithelioma of the breast: a case report.

The diagnosis of adenomyoepitheliomas is difficult and relies on the presence of a double component of epithelial and myoepithelial cells belonging to the breast lobules and ducts. The clinical and imaging characteristics are not specific; thus, the diagnosis is histological. In this article, we present a case of a young female who presented with a 2 cm lump in the breast without other clinical symptoms, which revealed a benign adenomyoepithelioma (AME). We performed a large excisional lumpectomy, and the patient recovered well with no complication or recurrence within two years follow-up. When it comes to adenomyoepitheliomas, the published literature is mainly composed of case reports, so much so that there are no evidence-based guidelines. Our case shows that an excisional lumpectomy is often enough when facing a small size tumor with no signs of malignancy, which contributes to the limited data on the subject.
