In conclusion, based on the data in this study as well as a literature review, the presence of epithelial atypia within a pleomorphic adenoma (ranging from isolated AR expression to apocrine metaplasia to overtly dysplastic/malignant epithelial cells) does not portend aggressive behavior (recurrence or metastasis) if the atypia is confined within the borders of the adenoma and negative margins are achieved. Here, AR is linked to adenoma.
