Recently we experienced a case manifested by a lump in both breast that mimicked carcinoma but was found to be a vasculitis of the giant cell type. Our case was characterized histologically by granulomatous arteritis involving small to medium sized arteries of the breast without involvement of the temporal artery. We described the clinical and pathologic features of a case of giant cell arteritis of the breast and reviewed the eight previously reported cases in foreign literature.
