Metastatic sclerosing mesothelioma in a cow.
Metastatic sclerosing mesothelioma in a crossbred cow is described. Accumulation of fluid in the abdominal cavity and solitary or coalesced nodules on the peritoneum, hepatic capsule and visceral pleurae, were observed after slaughter. Histological examination of the nodules revealed that they were composed of tubular structures supported by massive connective tissue. The lumina of the tubules were lined by solitary neoplastic mesothelial cells, or occasionally small groups of such cells were observed in the lumen. Identification of the mesothelial character of the tumours was dependent upon the histopathological and cytological characteristics of the nodules and histochemical stainings.
