Abstract
Twenty-two cases were reviewed in which the diagnosis of radial scar (complex sclerosing lesion) of the breast was suspected preoperatively. At mammography, the lesions had a "black star" appearance with long, thin spicules radiating from a radiolucent central area. Excisional rather than core needle biopsy was recommended in all cases. In 13 of 22 cases, including one case of atypical ductal hyperplasia, the lesions proved benign at pathologic analysis. The remaining nine cases were malignant and included one case with a low-nuclear-grade cribriform and micropapillary ductal carcinoma in situ adjacent to the lesion. Results of this study confirm the previously reported association of atypical ductal hyperplasia and carcinoma with radial scar. Furthermore, they demonstrate that a mammographic finding suggestive of radial scar may represent a malignancy that mimics the typical imaging findings in these entities. In cases of mammographically suspected radial scar, all members of the management team as well as the patient should be made aware preoperatively of the potential for benign as well as malignant pathologic findings.Keywords
