Abstract: Bovine liver telangiectasis is one of the most common liver lesions found in cattle throughout the world. Liver samples from 50 bovines with telangiectasis were examined by light microscopy. They were characterized grossly by single or multiple red-brown foci, generally 1-5 mm in diameter and occasionally larger. They were located on the parietal surface of the lobus dexter or rarely scattered throughout the organ. Microscopically, irregular and cystic dilation of hepatic sinusoids in all over the liver observed; these cysticcavities were full of red blood cells and in some cases fibrins with neutrophil in these cavities were distinguished. In finding of electronic microscope; marked dilation of diss spaces with red blood cells andcollagen and moderate sediment of fibrin were observed. This study is the 1st report on liver telangiectasisin cattle in East Azerbaijan province.
