a The resected specimen reveals a grayish white tumor that tightly adhered to the left brachiocephalic vein and the pericardium. b Pathologic findings of the resected specimen show collagenous fibrous tissue with scattered lymph follicles (hematoxylin and eosin stain, original magnification ×10). c The lymphoid follicles were surrounded by a broad mantle zone composed of concentric rings of small lymphocytes and the germinal centers exhibited hyalinized vascular proliferation (hematoxylin and eosin stain, original magnification ×100)
