[Malignant myoepithelial breast carcinoma: diagnosis and therapeutic difficulties].

Myoepithelial carcinoma of the breast is a rare and malignant tumor. Local recurrence and distant metastasis are common. Treatment is not consensual. Here, we report a case of a 61-year-old female who developed a myoepithelial carcinoma. Primary treatment was a local wide excision with clear pathological margins. Three years later, a local recurrence was treated by further wide excision. Neither recurrences nor distant metastasis were detected four years later. Regular following of patients with myoepithelial carcinoma is essential.
