Granular cell tumor. A 65-year-old woman presented for further evaluation of a focal asymmetry detected on screening mammopgrahy. Craniocaudal and lateral spot compression views (a, b) show a small irregular mass with spiculated margins (arrows). Color Doppler (c) and grayscale (d) ultrasound shows a corresponding irregular mass with internal vascularity (arrows). Core needle biopsy yielded granular cell tumor which was treated with surgical excision
