“…Cardoso et al (2004b) also reported 20% of cases with hyperglobulinemia; however, protein electrophoresis was not performed in their study. The excessive increase in production of immunoglobulin G interferes with platelet function, causing coagulation disorders and a hyperviscosity syndrome, which can lead to neurological, cardiac and renal disorders (Fighera et al 2002). However, no animal in this study showed clinical signs related to gammopathy.…”

“…The mediastinal form is characterized by enlarged of the cranial mediastinal lymph nodes and ∕ or thymus, and clinical signs include dyspnea, coughing, exercise intolerance and regurgitation (Teske 1994, Cardoso et al 2003. The vena cava syndrome, which is characterized by edema of the face, neck and thoracic members, can occur in this form (Fighera et al 2002). Dogs with the alimentary form of lymphoma usually present with non-specific gastrointestinal signs of vomiting, diarrhea and weight loss; mesenteric lymph nodes, liver and spleen may also been involved (Teske 1994, Fighera et al 2002.…”

Cutaneous lymphoma in the dog can be generalized or multifocal; and histologically they can be divided into epidermotropic (usually T-cell origin) and non-epidermotropic types (usually B-cell origin).…”

Bras. 34(4):349-354, abril 2014 349 RESUMO.-[Aspectos epidemiológicos, clínicos e imuno-histoquímicos do linfoma canino na região de Porto Alegre.] Esse trabalho apresenta os achados epidemioló-gicos, clínicos e imuno-histoquímicos de linfomas caninos diagnosticados na região de Porto Alegre. Trinta cães foram incluídos no estudo; sendo principalmente machos (60%), sem raça definida (23%) e de meia-idade a idosos. A maioria (87%) dos cães afetados apresentou a forma anatômica multicêntrica. O imunofenótipo B foi detectado com mais frequência (62%); 37% dos cães apresentavam estadiamento clínico IV e 83% encontravam-se no subestádio "b". Linfadenopatia foi observada em 67% dos casos; outros sinais clínicos comumente detectados foram dispneia, prostração, diminuição do apetite e vômitos. Anemia foi a alteração laboratorial mais frequente (57%), seguida por leucocitose (40%), trombocitopenia (33%), linfopenia (30%), hiperglobulinemia (20%), hiperproteinemia (17%) e hipercalcemia (13%). Os resultados do presente estudo indicam que as características epidemiológicas e clínicas de cães com linfoma na região de Porto Alegre são semelhantes às observadas em todo o mundo.TERMOS DE INDEXAÇÃO: Linfoma, síndromes paraneoplásicas, sinais clínicos, imuno-histoquímica, caninos. INTRODUCTIONLymphoma is the most common canine hematopoietic neoplasm, with reported incidences of 24 to 33 cases per 100,000 dogs (Dorn et al. 1967, Teske 1994. In Brazil, lymphoma is the second most common canine neoplasm leading to death or euthanasia (Fighera et al. 2008 This paper describes the epidemiological, clinical and immunohistochemical characteristics of canine lymphomas diagnosed in the region of Porto Alegre, Brazil. Thirty dogs were enrolled in the study; most of them were male (60%), mixed-breed (23%) and middle-aged or older. The majority (87%) of affected dogs showed the multicentric form. The B-cell phenotype was most frequently detected (62%); 37% of the animals were in clinical stage IV, and 83% were classified as sub-stage "b". Lymphadenopathy was observed in 67% of the cases, and dyspnea, prostration, decreased appetite and vomiting were the most common clinical signs encountered. Anemia was a frequently encountered laboratory alteration (57%), as were leukocytosis (40%), thrombocytopenia (33%), lymphopenia (30%), hyperglobulinemia (20%) and hypercalcemia (13%). The results of this study indicate that the clinical features of dogs with lymphoma in the region of Porto Alegre are similar to those observed worldwide.

“…Neoplasmas originários do sistema hematopoiético, como o linfoma, são os mais prevalentes entre animais jovens, especialmente em cães (Fighera et al 2002). Em suínos, acredita-se que estejam relacionados a uma herança autossômica recessiva (Jacobs et al 2002).…”

“…Nos linfonodos, macroscopicamente se observava substituição do parênquima nodal por massa homogênea, firme e branca; nos demais órgãos, os nódulos apresentavam tamanhos variados, entre 0,5 e 4,0 cm de diâmetro, de mesma cor, padrão e consistência, semelhante ao descrito para outras espécies (Fighera et al 2002, Fry & McGavin 2007. Microscopicamente, na coloração de rotina, eram caracterizados por proliferação de células redondas com limites citoplasmáticos distintos e citoplasma escasso e núcleo central e redondo, formado por cromatina agregada.…”

Neoplasms in swine are rare. This paper describes neoplasms found in swine in the diagnostic routine of a veterinary pathology laboratory in the Central Region of Rio Grande do Sul, Brazil during a 49-year period, during which 2,266 cases of the various affections in swine were diagnosed. Of those 37 cases (1.6%) were neoplasms. In decreasing order of prevalence, the following neoplasms were found: lymphoma (11 out of 37 cases), nephroblastoma (11/37), melanoma (8/37), and papilloma (2/37). Adenoma hepatocelular, carcinoma hepatocelular, cholangiocarcinoma, malignant fibrous histiocytoma, granulocytic sarcoma were each found in one case out of the 37 cases. The gross and histological aspects of these tumors are described and their epidemiology is compared with the data available in the literature for neoplasia in swine.
