Abstract |
Tumor masses from a Bengal tiger (Panthera tigris) of 13 years in age raised at the natural farm in Yong-In were examined grossly and microscopically. The tumors were observed in the subcutis, lung, heart, liver, pancreas, kidney, cecum and spleen. Histologically the tumors were composed of solid anaplastic cells that formed mature or immature small blood vessels and invaded the adjacent parenchyma. The nuclei of the tumor cells were large, vacuolated, and round or ovoid, sometimes dense and ovoid or spindle. The mitotic figures were common and the boundaries between the cells were indistinct. The stroma was very sparse. A diagnosis of this case was made as hemangiosarcoma on the basis of gross and microscopic features. |
