The miofibroblastoma is a benign tumor of the breast of very infrequent presentation that mainly affects the male breast. The main histological characteristic is the mesenchymal ancestry characterized by the proliferation of plump and spindle cells surrounded by collagen and that derive from fibroblasts. The surgery is the main treatment with preservation of the breast in female patients. We presented a case of a female patient of 64 years old, which presents a solitary tumor with progressive growth by 5 years, until she decides to ask for medical aid, considering the preoperating diagnosis of an tumor of mesenchymal type; which subsequent to the surgical treatment and confirmed by immunohistochemistry the presence of miofibroblastoma of the breast, being this finding very unusual in the clinical practice, and to be considered at the time of making differential diagnosis.
