Abstract
This retrospective study of neoplasia in nondomestic felids in human care presents the cases diagnosed at Northwest ZooPath (NWZP), Monroe, Washington, from 1998 to 2017 in conjunction with a scoping literature review. The 554 neoplasms identified in 20 species in the NWZP archive were combined with the 984 neoplasms identified in those same species in the published literature. Some of the cases identified in the literature were from the NWZP archive. Based on this review, mammary adenocarcinoma (183/1,483, 12.3%), lymphoma (89/1,483, 6.0%), squamous cell carcinoma (85/1,483, 5.7%), pheochromocytoma (57/1,483, 3.8%), and thyroid adenoma (57/1,483, 3.8%) are the most frequently reported neoplasms in nondomestic felids in human care. Apparent species predilections for neoplasia include mammary adenocarcinoma in tigers, jaguars, lions, and jungle cats; lymphoma in lions and tigers; squamous cell carcinoma in snow leopards; pheochromocytoma in clouded leopards; ovarian adenocarcinoma in jaguars; cholangiocarcinoma in lions and tigers; multiple myeloma in tigers; bronchoalveolar adenocarcinoma in cougars and lions; hemangiosarcoma, hepatocellular carcinoma, and gastrointestinal adenocarcinoma in lions; mesothelioma in clouded leopards, lions, and tigers; myelolipoma and cutaneous mast cell tumor in cheetahs; soft tissue sarcomas in tigers; and transitional cell carcinoma of the urinary bladder in fishing cats.

CLOUDED LEOPARD ( NEOFELIS NEBULOSA) MORBIDITY AND MORTALITY IN CAPTIVE-BRED POPULATIONS: A COMPREHENSIVE RETROSPECTIVE STUDY OF MEDICAL DATA FROM 271 INDIVIDUALS IN EUROPEAN, ASIAN, AND AUSTRALIAN ZOOS. J Zoo Wildl Med 2020; 51:150-158.

Abstract
The clouded leopard (Neofelis nebulosa) is classified as vulnerable on the International Union for the Conservation of Nature Red List of Threatened Species. However, diseases affecting this species across zoo populations are not well documented. The primary objective of this retrospective study was to identify common and significant causes of morbidity and mortality in captive-bred clouded leopards from European, Asian, and Australian institutions. Medical records from 44 zoological parks that held 271 clouded leopards from 1934 to 2017 were reviewed. Major causes of mortality in the dead leopards (n = 141) were respiratory disease (17%), maternal neglect and starvation (12%), generalized infectious disease (10%), digestive disease (10%), and trauma (10%). Six animals lived more than 20 yr and two were older than 22 yr. Diseases were recorded 344 times (average of two per leopard) in 166 living leopards. The body systems most frequently affected by disease in these 166 individuals were, in order of frequency, integumentary (prevalence = 21%), digestive (21%), respiratory (16%), musculoskeletal (12%), and urinary (10%) systems. Neoplasia (7%) was less frequent, followed by cardiovascular (5%), genital (3%), and viral (3%) disorders. Extensive, self-induced alopecia on the tail and dorsum was the most frequently reported dermatological disease, which is proposed to be called the "clouded leopard alopecia syndrome." The most common neoplasm was pheochromocytoma (1%), followed by squamous cell carcinoma of the paw pads, pleural mesothelioma and multicentric lymphomas (<1% each). Dilated cardiomyopathy (2%) was the most common cardiovascular disease. Bronchopneumonia (7%), enteritis (4%), and nephritis (4%) were the most frequently reported respiratory, digestive, and renal diseases, respectively. Diagnosed disease incidence was significantly higher in Europe. This paper reports the results of a comprehensive study of the causes of morbidity and mortality in European, Asian, and Australian clouded leopard zoo populations.

Abstract
Mesothelioma is a malignant tumor mainly correlated to occupational asbestos exposure. Rare reports describe its occurrence also in animals, mainly linked to asbestos in the environment. Asbestos exposure is demonstrated by the appearance of characteristic histological hallmarks: asbestos containing ferruginous bodies that are iron-based structures forming around fibers and also other dust particles. Here we present a clinical case of a suspect of mesothelioma in the peritoneum of a dog with parallel histological observation of ferruginous bodies. To possibly correlate the dog tumor to environmental exposure, we performed X-ray fluorescence (XRF) analyses at two different synchrotrons to resolve the ferruginous bodies' composition. While the histological examination diagnoses a tubulo-papillary mesothelioma, the XRF analyses show that ferruginous bodies contain Si particles, resembling formations of exogenous origin; however, the morphology is unlikely that of asbestos fibers. We speculate that the peritoneal mesothelioma of this dog could be related to environmental exposure to non-asbestos material.

Abstract
This retrospective study provides an overview on spontaneous diseases occurring in 38 captive wild felids submitted for necropsy by German zoological gardens between 2004 and 2013. Species included 18 tigers, 8 leopards, 7 lions, 3 cheetahs and 2 cougars with an age ranging from 0.5 to 22 years. Renal lesions, predominantly tubular alterations (intra-tubular concrements, tubular degeneration, necrosis, intra-tubular cellular debris, proteinaceous casts, dilated tubuli) followed by interstitial (lympho-plasmacytic inflammation, fibrosis, metastatic-suppurative inflammation, eosinophilic inflammation) and glomerular lesions (glomerulonephritis, glomerulosclerosis, amyloidosis) were detected in 33 out of 38 animals (87%). Tumors were found in 19 of 38 felids (50%) with 12 animals showing more than one neoplasm. The tumor prevalence increased with age. Neoplasms originated from endocrine (11), genital (8), lympho-hematopoietic (5) and alimentary organs (4) as well as the mesothelium (3). Most common neoplasms comprised uterine/ovarian leiomyomas (5/2), thyroid adenomas/adenocarcinoma (5/1), pleural mesotheliomas (3), hemangiosarcomas (2) and glossal papillomas (2). Inflammatory changes were frequently encountered in the intestine and the lung. Two young animals displayed metastatic mineralization suggestive of a vitamin D- or calcium intoxication. One tiger exhibited degenerative white matter changes consistent with an entity termed large felid leukoencephalomyelopathy. Various hyperplastic, degenerative and inflammatory changes with minor clinical significance were found in several organs. Summarized, renal lesions followed by neoplastic changes as well as inflammatory changes in lung and gastrointestinal tract represent the most frequent findings in captive wild felids living in German zoological gardens.

Abstract
A 21-yr-old female jaguar (Panthera onca) died in a zoo in Teresina, Piaui, Brazil, following a history of abdominal distension, ascites, anorexia, and dyspnea. At necropsy, a dark red, watery, blood-tinged serous fluid was present in the abdominal cavity. The peritoneum was thick with firm, yellow, villous projections. Histologically, the tumors were composed of a biphasic population of cells, which reacted to anti-cytokeratin and anti-vimentin antibodies, consistent with a biphasic benign mesothelioma of peritoneal origin. This is the first reported case of mesothelioma in a captive jaguar.

Abstract
An 18-year-old female lion (Panthera leo) was referred to the Department of Animal Pathology of the University of Turin (Italy). At necropsy, multiple nodular, 4-20-mm, confluent white firm nodules were scattered throughout the pleural surfaces of the thoracic wall and of the lungs. Histological lesions were represented by proliferations of papillary structures lined by cuboidal basophilic mesothelial cells with large, oval nuclei and abundant granular eosinophilic cytoplasm. Immunohistochemistry revealed immunoreactivity for pancytokeratin and vimentin. None of the cells expressed calretinin antigen. Asbestos fibers and asbestos bodies were not detected respectively by light microscopy and by Scanning Electron Microscope-Energy Dispersive Spectrometer investigations. On the contrary, chrysotile asbestos were identified in samples from shelter material. Histological and immunohistochemical findings were consistent with the diagnosis of an epithelial malignant mesothelioma. To our best knowledge, this is the first report of a pleural mesothelioma in a lion.

Abstract
This paper reports on an unusual case of pleural epitheloid mesothelioma in a nine-month-old male, mixed breed dog. The dog was presented in-extremis and, on post mortem examination, multiple, exophytic, frequently pedunculated, yellowish-red, soft to firm masses ranging from 3 mm to 6 cm in diameter were diffusely distributed over, and attached to, the pericardial and parietal pleural surfaces. Microscopically, these masses consisted of round to partially polygonalshaped, anaplastic cells with minimal cytoplasm and hyperchromatic nuclei covering papillomatous projections or as part of more densely cellular masses. A supporting fibrovascular stroma and mitotic figures were also evident. Constituent tumour cells were labeled positively with antibodies against both vimentin and cytokeratin. In contrast, the same cells exhibited equivocal labeling with an antibody directed against calretinin antigen and did not label with antibodies against carcinoembryonic antigen (CEA) and milk fat globule-related antigen (MFGRA). Such tumours are rare in dogs, particularly in such a young animal.
