@entity0 is rare. The case of a 61-year-old female is reported here. The @entity5 was clinically, radiologically and macroscopically demarcated. Diagnosis was based on histological and immunohistochemical studies. At the time of diagnosis the @entity5 consisted of myoepithelial cells with few cellular atypias and a low mitotic activity. @entity5 cells expressed @entity2277 , actin, @entity4483 protein and cytokeratin. No local or distant metastases were found. The @entity1 had been treated initially with a large excision of @entity5 . Local recurrences detected one year after initial surgery and showed a similar morphology and immunoreactivity with higher mitotic activity. Mastectomy with axillary dissection was performed. Neither recurrences nor distant metastases detected two years later. @entity20027 which are generally considered as benign or low-grade lesions can give rise to a wide range of clinical evolution.
