• Pleural mesothelioma in a California sea lion (Zalophus californianus). Y. Takami, M. Tanaka, M. Morita, et al. 2023;85(9):1030-1033. Case report PubMed · Publisher · Free full text

  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.

• Histological comparison of malignant epithelioid mesothelioma in young and adult cattle. Y. Kawashima, A. Fujimoto, M. Saito, et al. 2021;83(6):968-972. PubMed · Publisher · Free full text

  Abstract

  The histology and immunohistochemistry of pleomorphic and conventional epithelioid mesotheliomas were examined. The former was detected in two young calves aged 2 and 4 months and was characterized by pleomorphic and atypical cells with decreased expression of cytokeratin 7 (CK7). In contrast, the latter was found in a 31-month-old heifer, consisting of tumor cells uniform in size and shape with CK7 expression in nearly all cells. Production of collagen by tumor cells was demonstrated in both histological types, and was considered to be characteristic of bovine epithelioid mesothelioma. Pleomorphic mesothelioma is far more pleomorphic and mitotically active than conventional mesothelioma, and its normal counterpart may be immature mesothelial cells with high proliferation potential, which exist in fetal life and early calfhood.

• Multicystic peritoneal tumor in two layer hens. K. Yoshida, T. Miyoshi, T. Murakami. 2020;82(3):294-298. Case report PubMed · Publisher · Free full text

  Abstract

  In chicken, peritoneal cystic lesions have not been clearly categorized. In this study, diffuse peritoneal multiple cysts were observed in two layer hens. The cysts in the serosa were lined with single layers of squamous or cuboidal cells. The papillary proliferations of columnar cells were also observed in one case. The smooth muscle layer or mass were observed around the cysts in both cases. The cystic lining cells were positive for pan-cytokeratin, vimentin, S100 and Wilms tumor 1. Ultrastructurally, they had sparsely microvilli on the luminal surface. The histological results indicated the present cases were multicystic mesothelioma, but also had characteristics of Mullerian epithelium. This is the first report describing the detailed pathological feature of unique multicystic tumor in chicken.

• Peritoneal sarcomatoid mesothelioma in a sika deer. K. Matsuda, S. Kogame, R. Yaegashi, et al. 2019;81(10):1504-1508. Case report PubMed · Publisher · Free full text

  Abstract

  A slaughtered 2-year-old female sika deer (Cervus nippon yesoensis) had diffusely distributed multinodular lesions on the serosal surface of the peritoneal cavity and several nodules in the pleural cavity. Histologically, they were composed of proliferating spindle-shaped neoplastic cells, arranged in a fascicular fashion. The cells in the invasive foci transitioned from a sarcomatoid to an epithelioid appearance. Immunohistochemically, both the spindle-shaped and epithelioid cells were at least focally positive for pancytokeratin, vimentin, calretinin, α-SMA, and desmin. From these findings, the deer was diagnosed with peritoneal sarcomatoid mesothelioma with metastasis to the pleural cavity. To our knowledge, this is the first reported case of peritoneal mesothelioma in a cervid species and the first case of mesothelioma in a sika deer.

• Thoracoscopic pericardiectomy associated with fully implantable catheter via thoracoscopy in the management of mesothelioma in a bitch. H.F. Hartmann, M.T. DE Oliveira, J.P.S. Feranti, et al. 2019;81(6):946-948. Case report PubMed · Publisher · Free full text

  Abstract

  Mesothelioma is a very aggressive malignant tumor with low survival rates that is often diagnosed belatedly. Pericardial effusion is a common consequence in cases of mesothelioma, with pericardiocentesis and pericardiectomy indicated; therefor thoracocentesis is necessary to drain the contents no longer retained in the pericardium. The present report describes a mesothelioma-carrying dog with a history of cardiac tamponade that underwent thoracoscopic pericardiectomy and, later, thoracoscopic implantation of a fully implantable catheter to function as a thoracic drain. In the consulted literature, there is no use of a fully implantable catheter for this purpose. The authors consider that there was an improvement in the quality of life.

• Sarcomatoid mesothelioma of tunica vaginalis testis in the right scrotum of a dog. N.V. Son, J.K. Chambers, T. Shiga, et al. 2018;80(7):1125-1128. Case report PubMed · Publisher · Free full text

  Abstract

  A 12-year-old intact male Welsh Corgi was presented with enlargement of the right scrotum. Both testicles were surgically removed and histopathologically examined. On gross examination, white nodules were found in the epididymis and ductus deferens. Histopathologically, the nodules developed continuously from the tunica vaginalis testis of the right scrotum and consisted of spindle-shaped neoplastic cells that invaded the surrounding tissue. Immunohistochemically, the neoplastic cells were diffusely positive for vimentin, cytokeratin and Wilms tumor-1 (WT-1). Based on these findings, the tumor was diagnosed as sarcomatoid mesothelioma. The dog presented with respiratory distress 122 days after surgery and clinical examination found multiple metastatic lesions in the lung, abdominal lymph nodes and peritoneum. The dog died 144 days after surgery due to disease progression.

• Primary diffuse malignant peritoneal mesothelioma in a striped skunk (Mephitis mephitis). S.M. Kim, Y. Oh, S.H. Oh, et al. 2016;78(3):485-7. Case report PubMed · Publisher · Free full text

  Abstract

  A 10-year-old female striped skunk (Mephitis mephitis) was admitted with severe abdominal distension and lethargy. Cytological examination of the peritoneal fluid revealed activated mesothelial cells. At necropsy, numerous growing together, projecting, 2 to 20 mm in diameter tawny to white masses were scattered throughout the peritoneum including the mesentery, omentum and intestinal serosa. Microscopically, the tumor was composed of prominent papillo-tubular structures, and immunohistochemically, the spindle to polygonal-shaped tumor cells with nuclear polymorphism were strongly reactive for calretinin. Based on those diagnostic features, the neoplasia was diagnosed as malignant mesothelioma. This is the first case report of mesothelioma in the skunk.
