Abstract
Mesothelioma is a rare malignant neoplasm that affects the mesothelial cells lining the thoracic and abdominal cavities, such as the pleura, peritoneum, and pericardium. It is most prevalent in dogs and cattle, but the causes of this disease in animals are uncertain. In felines, it mainly affects the pleura, with an unfavorable prognosis. This paper explores a rare case of metastatic peritoneal mesothelioma in a 2-year-old female mixed breed cat, emphasizing its uniqueness due to the feline's age. The patient, previously treated at a private clinic, presented moderate abdominal distension as the only clinical sign. Abdominal ultrasound and peritoneal fluid cytology led to the provisional diagnosis of mesothelioma/carcinomatosis. One day after exploratory laparotomy, the animal died and was subsequently sent for necropsy. During macroscopic analysis, nodules were observed in the peritoneum, diaphragm, omentum, stomach serosa, and large intestine, and the diagnosis of solid epithelioid peritoneal mesothelioma with lung metastasis was confirmed after microscopic analysis. The diagnosis of mesothelioma is challenging, and the importance of immunohistochemical panels with specific markers such as cytokeratin AE1/AE3 and calretinin is highlighted. Considering that mesothelioma is a pathology with a poor prognosis, it is essential to include this disease in the list of differential diagnoses within veterinary oncology.

Abstract
A 25-year-old female California sea lion (Zalophus californianus) reared in an aquarium died following a history of anorexia, lethargy, abnormal protrusion of the skin, and oral respiration. At necropsy, multiple yellowish-white nodules with diameters of 0.1-0.5 cm were disseminated in the thoracic cavity and lungs. Histopathologically, the nodules were continuous with normal mesothelium and were characterized by the proliferation of spindle-shaped to polygonal neoplastic cells with prominent atypia. The neoplastic cells exhibited diffuse, strong staining for vimentin and partial, weak to moderate staining for cytokeratin AE1/AE3. Based on these findings, the lesions were diagnosed as pleural mesothelioma. This study reports the first case of pleural mesothelioma in California sea lion.

Abstract
A 7-year-old female German Shepherd Dog was presented with multiple petechiae and ecchymoses along the ventral abdomen, flank, and on the vaginal mucosa. The clinical diagnosis was severe hemoperitoneum and presumed disseminated intravascular coagulopathy. Postmortem examination revealed a 22 cm × 15 cm × 6 cm, firm, and convoluted peritoneal mass along with hemoperitoneum, and multifocal, ill-defined, 0.5-1.5 cm in diameter, white to tan nodules in the pulmonary parenchyma. Histologically, the peritoneal mass was composed of large anaplastic cells consistent with malignant mesothelioma interspersed in abundant fibrous connective tissue. Metastasis of the neoplastic cells occurred to the brain, adrenal glands, lymph nodes, and lungs. On immunohistochemical evaluation, neoplastic cells coexpressed cytokeratin and vimentin, and were negative for cluster of differentiation (CD)18. Electron microscopy revealed numerous surface microvilli around the entire circumference of the neoplastic cells, as well as tight junctions, and desmosome-like structures. Based on test findings, a disseminated sclerosing peritoneal mesothelioma was diagnosed.

Abstract
The adenomatoid tumor is an uncommon benign lesion, thus far described only in humans. Adenomatoid tumors typically arise in the genital tract, exceptionally in the heart, and usually represent an incidental finding. Microscopically, they are constituted by epithelioid cells that form tubular structures and anastomosing channels within a fibrous stroma. Mesothelial origin of these lesions is suggested by their immunohistochemical characteristics. In cattle, previously reported myocardial epithelial inclusions are morphologically similar in that the cells are immunoreactive for both cytokeratins and vimentin, and bear surface microvilli. Myocardial lesions found incidentally at slaughter in 8 cattle histologically resembled the so-called bovine myocardial epithelial inclusions and had morphologic and immunohistochemical features consistent with human adenomatoid tumor. All lesions were in the left ventricular myocardium, adjacent to the epicardium, and composed of epithelioid cells that formed cords and tubules, and were immunoreactive for pan-cytokeratins, cytokeratin 5/6, vimentin, calretinin, Wilms' tumor 1 suppressor gene, and CD30 antigen. By electron microscopy, numerous long slender microvilli were associated with desmosomes and tonofibrils. The immunohistochemical and ultrastructural features were considered consistent with mesothelial origin. These lesions, corresponding to the previously described myocardial epithelial inclusions in cattle, might be considered embryologic rests and could represent the bovine counterpart of the human adenomatoid tumor.

Abstract
An 11-year-old, neutered, male Golden Retriever cross dog was euthanized following a history of recurrent pericardial effusions. At necropsy, blood-tinged pericardial and intrathoracic effusions were seen along with numerous firm to hard plaque-like masses that studded the epicardial, pericardial, mediastinal, and costal pleural surfaces. Within the right thorax, the lesions coalesced into a large mass that occupied most of the cavity. Histologically, the masses were composed of solid sheets and papillary aggregates of medium-sized polygonal cells that contained abundant vacuolated to clear cytoplasm. Some of the cytoplasmic vacuoles stained positive with oil red O. The stroma contained metaplastic trabeculae of woven and lamellar bone. Immunohistochemically, the neoplastic cells expressed vimentin, pancytokeratin, and S-100 protein. Transmission electron microscopy corroborated the presence of intracytoplasmic vacuoles and demonstrated prominent intercellular junctional complexes and apically located microvilli. These findings are consistent with a lipid-rich variant of mesothelioma. To the authors' knowledge, this is the first report of a lipid-rich mesothelioma in a dog.

Abstract
A 28.5-year-old female Japanese macaque (Macaca fuscata) was euthanatized because of abdominal distension due to severe ascites. Nodular lesions of varying sizes up to 5 mm in diameter were distributed diffusely on the surface of the omentum, mesentery and parietal peritoneum. No neoplastic masses were detected in any visceral organ. The nodules were composed of proliferation of mono- or multi-layered epithelial-like cells occasionally showing papillary growth and sheets of small round or polygonal cells. Signet ring-like cells and tubular structures were occasionally present. Neoplastic cells were strongly positive to cytokeratin, and occasionally to vimentin. Based on gross and histopathological findings, this tumor was diagnosed as an epithelial type of peritoneal malignant mesothelioma, the first reported case in the non-human primates.
