[Adenomyoepithelioma with dominant myoepithelial contingent of the breast: A case report and literature review]. / Adénomyoépithéliome avec contingent myoépithélial prédominant du sein : à propos d'une observation et revue de la littérature.

ABSTRACT

We report a case of adenomyoepithelioma with predominant myoepithelial quota, a rare tumor of the breast due to proliferation of epithelial and myoepithelial cells in a patient of 71 years. This lesion, with difficult radiological and pathological diagnosis (biopsy) in the initial stage of the treatment, should benefit from surgical resection in healthy margin. In fact, this tumor is evolving in most cases on a benin mode, but cases of local or metastatic recurrences were reported. Histological and immunohistochemical arguments are important to reach the final diagnosis.
