Ultrasonography ; Breast Neoplasms, Male ; Granular cell tumor
Abstract
Granular cell tumor of the breast is a rare tumor arising from Schwann cells. Although it is usually a benign tumor, its characteristics can mimic those of breast carcinoma clinically, radiologically, and macroscopically. The tongue is the single most common anatomic site involved; however, a granular cell tumor may arise in virtually any site of the body. We report on a 67-year-old male patient with a palpable breast mass presenting as an irregular mass on mammography and ultrasound.
