Seminoma and Cholangiocarcinoma in an 18-Year-Old Male Camel

Abstract: Herein, diffuse-type seminoma and intrahepatic cholangiocarcinoma in an 18-year-old male camel are described. The seminoma was located on the right testis (11 × 8.5 × 4.5 cm) and the cut surface of the tumor had a lobulated appearance. The tumor cells disseminated diffusely in the tumoral stroma with hemorrhages, and multiple necrotic foci were seen with microscopic examination. Additionally, the liver was enlarged, firm, and grayish-white; multiple lesions were observed both on the serosal surface and in the cut surface of the liver. Microscopically, the intrahepatic cholangiocarcinoma was composed of gland-like structures and/or solitary islands of neoplastic cells in the tumoral stroma. This is the first reported case of these 2 tumors simultaneously presenting in a camel.
