Malignant tumors of the mammary gland - most commonly invasive ductal carcinoma (according to the new histological classification invasive carcinoma NST - no special type) and invasive lobular cancer are most frequently seen in the locally advanced breast tumors with ulceration of the skin. This report describes a histologically rare case of locally advanced malignant breast adenomyoepithelioma. A patient with locally advanced exulcerated breast tumor, with benign preoperative histopathological finding of benign adenomyoepithelioma, underwent a radical mastectomy at our department. The definitive histology suggests that it was a benign adenomyoepithelioma with supposed malignant epithelial component. In locally advanced tumors of benign histological type, it is necessary to think about the transient forms of these tumors or the possible malignancy of one of the components of histologically diverse tumors. According to uncertain nature of adenomyoepitheliomas, surgical resection with negative resection margins should always follow.

Keywords: adenomyoepithelioma, epithelial-myoepithelial lesions, breast tumor, carcinoma.
