This report describes a primary central nervous system B-cell lymphoma in a 3-year-old intact female Maltese dog. Canine primary central nervous system lymphomas constitute about 4% of all intracranial primary neoplasms, but comprehensive histopathologic classifications have rarely been carried out. This is the first report of this disease in a young adult dog. 相似文献

An 8-month-old, intact male Golden Retriever with a history of left forelimb lameness for 2 months was presented to the Veterinary Medical Teaching Hospital of Konkuk University (Seoul, Korea). Results of a physical examination revealed a mass in the left axillary region. A thoracic radiography showed an osteolytic lesion in the scapula and the presence of a soft tissue density from the thoracic wall to the scapula. A computerized tomography revealed a mass invading into the scapula, and small nodules in the lung that suggested metastasis. At necropsy, a pale-yellow, irregular, firm, 8 x 10 x 5 cm mass extended from axillary region and destroyed the scapular. In addition, small nodules were noted in the lung. On microscopic examination, the mass consisted of round-to-oval cells, with eccentrically located hyperchromatic nuclei and eosinophilic cytoplasm in fibromyxoid stroma. Tumor cells were observed in blood vessels in the primary mass. Tumor cells strongly expressed vimentin, desmin, and myoglobin. In phosphotungstic acid-hematoxylin staining, cross-striations were detected in rhabdomyoblasts. In periodic acid-Schiff reaction, only a few cells were detected. The diagnosis was primary rhabdomyosarcoma of the appendicular muscle of a young dog. The tumor presumably originated in the skeletal muscle of the limb, invaded into the adjacent scapular bone, and metastasized to the lung. 相似文献

Canine end-stage renal disease (ESRD) is defined as the almost complete failure of renal function or irreversible destruction and is characterized by extensive glomerular sclerosis, tubular atrophy, interstitial inflammation, and fibrosis. Renal fibrosis is a common pathway leading to kidney failure. Infiltrating immunocytes in the end-stage kidney and several related factors are involved in renal fibrogenesis. A total of 18 renal tissue samples were obtained from canine patients with ESRD using biopsy and necropsy procedures. The extent of renal fibrosis was histopathologically examined by Masson trichrome staining. T-cell and B-cell localization and macrophage lineages were determined by immunohistochemical staining. Additionally, interleukin-1 (IL-1), IL-2, and IL-6 levels in the canine ESRD kidney were immunohistochemically evaluated and compared with expression patterns in the normal kidney. Significant fibrosis and infiltrating immunocytes consistent with lymphocytes were observed. Although the B-cell count was increased in the end-stage kidney, immunostaining patterns disclosed a marked increase in the number of CD3(+) cells. Furthermore, the remarkable increase in IL-1 and IL-6 levels suggests that T cells in the kidneys of dogs with ESRD spontaneously express these cytokines. In this study, the correlation between the degree of renal fibrosis and cytokines in canine ESRD was examined. The present study shows that T lymphocytes and IL-6 play important roles in renal fibrosis. 相似文献

Primary testicular tumors are the most common causes of cancer in male dogs. Overall, the majority of canine patients should be cured by testicular surgery. However, tumor markers are not well-known in veterinary medicine. We sought to determine using immunohistochemistry whether the combined human testicular tumor markers (placental alkaline phosphatase, OCT3/4, CD30, alpha-fetoprotein, inhibin-alpha, vimentin, c-KIT, and desmin) are expressed in canine seminomas and Sertoli cell tumors (SCTs). We examined 35 canine testicular tumors, 20 seminomas and 15 SCTs. c-KIT was expressed markedly in canine seminomas. Both inhibin-alpha and vimentin were expressed significantly in canine SCTs. The results of this study demonstrate differences and similarities between tumor marker expression of testicular tumors in dogs and humans. All the main markers in current routine use are discussed as well as potential useful markers for benign and malignant tumors, and tumor progression. 相似文献

Peribiliary cysts associated with severe liver disease: a previously unrecognized tumor in a lion (Panthera leo). 总被引:1,自引:0,他引:1

A 13-year-old male lion (Panthera leo) from Dae Jeon Zoo, Republic of Korea, presented with clinical signs of lethargy and anorexia. Despite treatment with antibiotics and fluid therapy, the lion died 6 days after initial presentation. Postmortem examination revealed multiple masses measuring 5-10 cm in diameter and cysts throughout the liver. A diagnosis of spontaneous peribiliary cysts was made on the basis of microscopic lesions as well as special staining and immunohistochemical characteristics. Histologically, the neoplasm was surrounded and composed of compact collagenous tissue. The inner cystic single layer resembled biliary mucosa and was composed of cuboidal or flattened epithelial lining that was strongly immunopositive for cytokeratin AE1/AE3. This layer was surrounded by fibrous tissue that stained blue by Masson's trichrome staining. Given the presence of multiple organized cysts in the liver, the lesion was consistent with peribiliary cysts. To the authors' knowledge, this is the first report of peribiliary cysts in an animal. 相似文献

巴氏杆菌病又叫出血性败血症,简称出败,主要是由多杀性巴氏杆菌所引起的各种畜禽和野生动物感染的一种传染病。临床特征急性病例主要表现为败血症和炎性出血,慢性特征表现为皮下组织、关节、各脏器的局灶性化脓性炎症。该病常在畜禽中发生,而在狐狸等经济动物方面报道相对较少。2006年秋,吉林左家某狐场的狐狸突然发病并陆续死亡,经流行病学调查、病理剖检和实验室检验,确诊为多杀性巴氏杆菌感染所致。 相似文献

HER-2 and HER-3 are transmembrane receptor proteins that are considered to be important but poorly understood biomarkers in canine tumors. In this study, the expression and the localization of HER-2 and HER-3 were evaluated immunohistochemically in canine mammary tumors (n = 64; 12 benign, 52 malignant).HER-2 overexpression was identified in 2/12 (16.7%) benign and in 18/51 (35.3%) malignant cases. HER-3 was expressed in a non-nuclear localization in 11/12 (91.7%) benign and 18/52 (34.6%) malignant tumors. In contrast, HER-3 was expressed in the nucleus of neoplastic cells in 0/12 (0%) benign and 22/52 (42.3%) malignant tumors. Nuclear HER-3 expression was higher in neoplastic epithelial cells compared to myoepithelial cells, and positively correlated with high histological grade and lymphatic vessel invasion. These results suggest that nuclear HER-3 expression is significantly associated with tumor progression and metastasis and may serve as a useful prognostic biomarker in canine malignant mammary tumors. 相似文献

ABSTRACTCase history: Gradual onset of ocular opacity was observed in three gold-striped geckos (Woodworthia chrysosiretica), and five Pacific geckos (Dactylocnemis pacificus) held in two adjacent terrariums in a zoological institution located in the North Island of New Zealand. Ultraviolet light and heat had been provided for the previous 3–4 years by a fluorescent bulb, but in the last 4 weeks of winter a ceramic heat bulb had been added, situated 10?cm above the upper mesh of the cageClinical findings: All eight geckos presented with mostly bilateral lesions of varying severity confined to the central or upper quadrant of the spectacles. These lesions ranged from variable areas of opacity within the stroma of the spectacle to similarly distributed ulcers of the surface epithelium of both spectacles. The spectacle lesions in the Pacific geckos responded well to treatment with topical combined antimicrobial therapy, within 18–29 days. The gold-striped geckos suffered complications including dysecdysis, severe spectacle ulceration and perforation, mycotic spectaculitis, and widespread mycotic dermatitis resulting in death or leading to euthanasia.Pathological findings: In the three gold-striped geckos, there were extensive areas of deep ulceration and replacement of the spectacle with a thick serocellular crust containing large numbers of fungal elements. The affected areas of the stroma were expanded by large deposits of proteinaceous and mucinous material, pyknotic cellular debris and moderate numbers of heterophils and macrophages as well as infiltrating fungal hyphae.Diagnosis: Mycotic spectaculitis with ulceration and perforation, and disseminated mycotic dermatitis likely secondary to thermal burns.Clinical relevance: This is the first report of thermal burns of the spectacle in any reptile. There was species variation in the burn severity with gold-striped geckos showing more severe lesions, possibly due to a mix of behavioural and anatomical factors. The thermal burns to the spectacles in three cases were complicated by delayed healing, perforation, dysecdysis and severe mycotic infection. 相似文献
