Morphological Classification of Hepatic Tumours in One-Humped Camel (Camelus dromedarius)

Camels rarely develop hepatic tumours. Forty six livers with tumour lesions from camels that had been slaughtered over a period of 3 years in the biggest abattoirs in Cairo, Egypt, were used in this investigation. The morphological and histological analyses of the hepatic lesions gave rise to a sufficient overview of the possible tumours that could develop in camel livers, whether they were neoplastic or not. Out of 46 cases, 40 cases (87%) had non-neoplastic tumours and six cases (13%) had neoplastic tumours. Out of 40 non-neoplastic tumours, 25 camels with hepatic hydatidosis constituted 54.3% of all hepatic tumours in the examined livers. Chronic hepatitis with hyperplasia or granulomatous lesions (n = 9, 19.5%), abscesses (n = 5, 10.8%) and hepatic lipomatosis (n = 1, 2.2%) were among the other non-neoplastic tumours. Cavernous haemangioma (n = 2, 4.4%), hepatocellular carcinoma (n = 2, 4.4%), cholangiocarcinoma (n = 1, 2.2%) and leiomyoma (n = 1, 2.2%), were among the neoplastic lesions that were noted. In conclusion, the majority of the one-humped camels’ hepatic tumours were non-neoplastic. However, there were also reports of neoplastic liver tumours, such as cavernous haemangioma, cholangiocarcinoma, hepatocellular carcinoma and leiomyoma. Lipogranuloma and hepatic lipomatosis in camels have been identified histologically.
