Figure 1: Granulomatous phlebitis of small hepatic vein. A: Epithelioid granulomas (arrows) and epitheliod cells were found in the walls of affected hepatic vein. B: A higher magnification of venous wall of A. In addition to epithelioid granuloma, there were also other inflammatory cells in the venous wall and beneath the endothelial cells. C: Sublobular hepatic vein showed diffuse granulomatous phlebitis. D: A higher magnification of venous wall of A. In addition to epithelioid cells, there were also other inflammatory cells beneath the endothelial cells. *, venous lumen. A: H&E, 50X; B: H&E, 150X; C: H&E, 100X; D: H&E, 200X.
