【摘要】 <正> 在兽医文献中,有关畜禽间皮细胞瘤的报道很少。据Smith(1966)统计六种家畜(狗、牛、马、猪、羊、猫)的8,159例肿瘤中,共发现间皮细胞瘤23例,占0.28％。其中牛比较多些,在1,371例肿瘤中有19例,占1.3％;狗5,854例中仅有3例,占0.05％;猪167例中有1例,占0.6％;马(464例)、羊(129例)及猫(174例)均未发现间皮细胞瘤。家禽中仅鸡有少数病例报告。鸭的间皮细胞瘤则尚未见到正式报告。更多还原

【Abstract】 The mesothelioma is a rather rare tumor among the domestic aninals and poultry. There are no reports in the literature of mesothelioma in ducks. The authors reported a high incidence of malignant mesothelioma in a group of 50 experimental ducks, that fed a diet containing mouldy corn (contaminated with aflatoxins) for a period of 13 months. 19 cases of malignant mesothelioma, including 9 cases coexist with primary hepatocarcinoma, was induced. A preliminary studies on the histological classification and etiology of these tumors was discussed. Macroscopically, 15 cases had multiple tumors and diffuse spread over the serous surfaces of the pleura and peritoneum. In 4 cases where one or two solitary nodules localized on the inner surface of the sternum. Histologically, according to the cell components and tissue arrangement, present study suggests the duck malignant mesothelioma may be classified into four types: epithelial (subdivided into papillary, cordlike, tubular and cystadenocarcinomatous), fibrous (fibrosarcomatous), mixed and pleomorphic cell type. The histological pattern of each type of tumors was described.更多还原
