Fig 2 Pathologic findings of the surgical specimen of the aorta. A, Macroscopic image showing diffuse and tumorous thickening of the arterial wall. B, Microscopic image showing intense inflammatory change and fibrosis in the adventitia. Inflammatory cells are mainly lymphocytes, plasma cells, and eosinophils (hematoxylin and eosin, original magnification ×40). C, Immunostaining of IgG4 revealed numerous IgG4-positive plasma cells within the lesion (immunostaining of IgG4, ×400 original magnification).
