Granular Cell Tumor Simulating Breast Malignancy: A Case Report

Granular cell tumor is a rare and usually benign tumor that occasionally involves the breast. The physical examination, the mammographic and ultrasonographic findings and the pathologic findings are often suggestive of carcinoma. We report here a rare case of granular cell tumor of the breast that mimicked carcinoma on the mammography, ultrasonography and MR imaging.
