Miofibroblastoma mamario en paciente posmenopáusica

Breast myofibroblastoma usually develops in postmenopausal patients and is a unilateral, painless and mobile tumor. Growth is slow and, unlike the case presented here, the margins are not usually invasive. The key features to exclude a diagnosis of cancer are the typical characteristics of breast myofibroblastoma and histological and immunohistochemical studies. Although the tumor recurred in our case, the preferred treatment is tumorectomy because there is a low rate of recurrence.
