We report a rare case of radial scar of the breast in a 42-yearold woman. Although no palpable mass was noticed, mammography, CT, and echography indicated scirrhous carcinoma. Fine needle aspiration showed benign ductal epithelial cells with myoepithelial cells and spindle stromal cells with hyalinized collagenous deposits. The lesion was histologically characterized by epithelial proliferations and stellate fibrosis with central hyalinized deposits.The finding of benign proliferative epithelium, spindle stromal cells, hyalinized collagenous deposits in conjunction with characteristic mammographic appearance is indicative for a diagnosis of radial scar.
