We describe a sclerosing granular cell tumor of the breast simulating fibromatosis. Clinically it simulates carcinoma because of its fibrous consistency and fixation to the greater pectoral muscle. The mammograms showed a rounded density with a slightly irregular margin in the upper, inner and outer quadrant of the left breast. Ultrasound showed a poorly defined solid lesion disrupting fascial planes. Clinical, radiological histological and therapeutica aspects are discussed.
