Successful Treatment of Mediastinal Unicentric Castleman’s Disease Using Video-Assisted Thoracoscopic Surgery with Preoperative Embolization
Figure 2
(a) and (b) Aortic angiogram with selective bronchial arteriogram demonstrated the tumor as a dense capillary blush, the arterial supply of which originated mainly from the branches of the right bronchial artery (arrowhead) (a). Embolization of feeding branches resulted in the near complete occlusion of the tumor vessels (b). (c) Histopathology of surgical specimen. The tumor was composed of lymphoid follicles with an expanded mantle zone forming concentric rings (i.e., an “onion-skin” pattern) and hyalinized vascular proliferation penetrating the lymphoid follicle (i.e., a “lollipop” appearance, arrowhead) (hematoxylin-eosin (HE) stain, ×100).
