Vascular lesions of the breast are uncommon, however, these are increasingly encountered now due to more frequent use of magnetic resonance imaging. They comprise a spectrum of lesions including benign, atypical, and malignant tumors. The prototype is a hemangioma, which is most often nonpalpable and is detected on routine screening. Different histopathologic subtypes of hemangioma have been described, including perilobular, venous, cavernous, and capillary hemangioma. Other benign vascular lesions include anastomosing hemangioma, a well-circumscribed proliferation of anastomosing blood vessels with lobular or diffuse growth pattern which affects a large segment of the breast, presenting as a painless slow enlarging palpable mass. Recent data suggest that benign vascular lesions diagnosed on core needle biopsy with concordant radiologic and pathologic findings do not require excision and have an excellent prognosis, except angiomatosis, which can be locally aggressive and may recur. The main focus of this study is to present the radiographic, gross, and histopathologic characteristics of benign vascular lesions of the breast and their differential diagnoses.
