Plain-English summary
In this case, a mare was diagnosed with a type of cancer called mesothelioma, which affects the lining of the chest. The diagnosis was based on several factors, including a large amount of fluid in her chest, the presence of unusual-looking cells, and the formation of growths called polyps. Additionally, a specific test showed that certain materials were absent in the cells, helping to confirm the diagnosis. This type of cancer is not very common, and it can be tricky to tell apart from other conditions that cause inflammation. The outcome of the treatment was not mentioned in the abstract.
Abstract
Examination of effusions from body cavities must include a search for neoplastic as well as inflammatory cells. Neoplastic cells found in the thorax are generally derived from adenocarcinomas or mesotheliomas. Mesotheliomas are relatively uncommon and the neoplastic cells found in effusions are difficult to differentiate from activated cells in inflammatory effusions. An ante-mortem diagnosis of mesothelioma was made in a mare on the basis of the large volume of fluid produced, the pleomorphic mesothelial cells, the polyp formation and the absence of PAS staining material after digestion of the cell impression with maltase diastase.
