“…LPL is defined as a small B-cell lymphoma with plasmacytic differentiation [2,10,12,13]. It is composed predominantly of lymphocytes, but plasmacytoid or typical plasma cells are an essential component [2,10,12,13]. The differential diagnosis between LPL and lymphomas, especially other small cell lymphomas and plasmacytoma, is not always clear [1].…”

In veterinary medicine, LPL is defined by the World Health Organization (WHO) and has been described in other studies [2,12,13]. It occurs in several domestic species, such as dogs, cats, cattle, and horses [2,12,13].…”

ABSTRACT. A lymphoplasmacytic lymphoma was diagnosed in a 12-year-old domestic cat that had a primary cutaneous mass involving the stomach, liver, kidneys, heart, abdominal wall, diaphragm, bone marrow and several lymph nodes. Histopathologically, the most characteristic feature of this tumor was the heterogeneity of cell components, such as small lymphocytes, well-differentiated plasma cells and plasmacytoid transformed lymphocytes. Amyloid was deposited in the skin, stomach, and several lymph nodes. Immunohistochemically, neoplastic small lymphocytes were positive for CD20, and well-differentiated plasma cells and plasmacytoid transformed lymphocytes were positive for -Ig light chains and MUM1/IRF-4. These results emphasize the importance of lymphoplasmacytic lymphoma as a differential diagnosis of extramedullary cutaneous plasmacytoma in cats.KEY WORDS: feline, lymphoplasmacytic lymphoma, skin.

“…Na forma entérica da doença há alargamento da submucosa do abomaso. Pode haver o envolvimento dos linfonodos mesentéricos, associados com a infiltração do abomaso, sendo que estes podem se apresentar com volume suficiente para causar obstrução (Valli 1993), conforme ocorrido em alguns animais desse estudo. Radostits et al (2007) e Barros (2007) relatam a presença de massas tumorais de aspecto firme e de coloração branco-amarelada, em qualquer órgão, sendo que o abomaso, o coração e a medula são os órgãos geralmente envolvidos.…”

591Pesq. Vet. Bras. 31(7): 591-597, julho 2011 RESUMO.-Neste trabalho são descritos os sinais clínicos, patologia clínica e patologia de 24 bovinos com leucose bovina enzoótica atendidos na Clínica de Bovinos de Garanhuns da Universidade Federal Rural de Pernambuco. Esses casos representaram 0,5% de 4.758 bovinos atendidos entre os anos de 2000 e 2010. A doença afetou 22 (91,7%) fêmeas e dois machos. Vinte e um animais (87,5%) eram de raças leiteras (seis Holandês, 13 Girolando, um Jersey e um Pardo Suíça) e três (12,5%) eram da raça Nelore. Vinte e três animais (95,8%) tinham idade entre 3 e 8 anos e um era mais jovem. Todos eram criados em regime de confinamento ou semiconfinamento. Clinicamente todos os animais apresentaram aumento dos linfonodos superficias. Outros sinais frequentes foram hiporexia, diminuição da produção de leite, emagrecimento progressivo, escore corporal baixo, desidratação, hipomotilidade dos pré-estômagos e fezes alteradas e em pouca quantidade. Com menor frequência foram observados exoftalmia, dispneia e aumento de volume do útero. No leucograma foi constatada leucocitose média de 34.082/μL, com linfocitose de 21.814/μL e neutrofilia de 10.906/μL. Treze animais foram necropsiados e os demais foram enviados pelos proprietários para o abate. Dos treze animais abatidos todos apresentaram lesões nos linfonodos superficiais, seis nos linfonodos mesentéricos, seis no intestino, três no abomaso, um no coração, um no fígado, um no rúmen, um no útero e um no rim. Diante da importância desta enfermidade The article reports epidemiological data, clinical signs, and laboratory and pathological findings in 24 cattle with enzootic bovine leukosis observed in the Clinic of Garanhuns, at the Federal Rural University of Pernambuco. The 24 cases represented 0.5% of 4,758 cattle examined from 2000 to 2010. The disease affected 22 (91.7%) females and two males. Twenty one of the animals were dairy (six Holstein, 13 girolando, one Brown Swiss and one Jersey), and three were for meat production (Nelore). Twenty three animals were 3-8 years of age and one was younger. All were raised in confinement or semi-confinement. All animals showed enlarged superficial lymph nodes. Other frequent clinical signs were hyporexia, decreased milk production, progressive weight loss, dehydration, hypomotility of the fore stomachs, and altered scant feces. Exophthalmia, dyspnea, and enlarged uterus were observed with less frequency. Leukocytosis (mean of 34,082 leukocytes/μL) with lymphocytosis (21,814 lymphocytes/μL) and neutrophilia (10,906lymphocytes/μL) was observed in the white blood count. Thirteen bovines were necropsied and 11 were slaughtered. Gross lesions were observed on the superficial lymph nodes of all animals necropsied. Six had lesions in the mesenteric lymph nodes, six in the gut, three in the abomasum, two in the uterus, one in the heart, one in the rumen, one in heart, and one in the liver. Due to the importance of enzootic bovine leukosis it is necessary for the farmers to introduce animals free of the...

“…Yersinia pseudotuberculosis is widely distributed in cold regions, and is classified as serotypes O1 to O14, in which the serotypes O1 to O5 are almost all pathogenic to humans (Fukoshima et al, 2001). The bacteria can infect many mammals and birds, with formation of characteristic caseonecrotic foci and pyogranulomatous lesions in viscera and lymphoid tissue (Valli, 1985). The most common mode of transmission is by food or water contaminated with faecal material, and by predation of carrier animals (Wanger, 1998).…”

Acute toxoplasmosis in three wild arctic foxes (Alopex lagopus) from Svalbard; one with co-infections of Salmonella Enteritidis PT1 and Yersinia pseudotuberculosis serotype 2b

Acute disseminated toxoplasmosis was diagnosed in three wild arctic foxes (Alopex lagopus) that were found dead in the same locality on Svalbard (Norway). The animals included one adult female and two 4-months-old pups. The adult fox was severely jaundiced. Necropsy revealed multifocal, acute, necrotizing hepatitis, acute interstitial pneumonia, and scattered foci of brain gliosis, often associated with Toxoplasma tachyzoites. One pup also had Toxoplasma-associated meningitis. In addition, the latter animal was infected with Yersinia pseudotuberculosis serotype 2b and Salmonella Enteritidis phage type 1 (PT1), which may have contributed to the severity of the Toxoplasma infection in this animal. The diagnosis of toxoplasmosis was confirmed by positive immunohistochemistry and detection of anti-Toxoplasma gondii antibodies in serum of all foxes. The animals were negative for Neospora caninum, canine distemper virus, canine adenovirus, and rabies virus on immunolabelling of tissue sections and smears.
