Multicentric lymphoma with metastasis in the central nervous system in a dog Arq. Bras. Med. Vet. Zootec.
Aptekmann,K.P.; Okamoto,C.E.; Campos,K.C.H.; Takahira,R.K..
Multicentric lymphoma was diagnosed in a two-year-old dog with respiratory distress, dysorexia, abdominal enlargement and generalized lymphadenopathy. Immunohistochemical examination showed T-cell origin with CD3+ e CD79- expression. After five weeks, progressive neurological deficits and neoplastic lymphocytes were identified in the cerebrospinal fluid. Histopathological examination showed neoplastic cell invasion in the spleen, lymph nodes, cerebrum and cerebellum.

Epitheliotropic lymphoma with heart and kidney metastasis in a dog: case report Arq. Bras. Med. Vet. Zootec.
Araújo,C.M.T.D.; Pacheco,B.D.; Castro,J.L.C.; Farias,M.R.; Engracia Filho,J.R..
ABSTRACT A female adult dog, with a four-month history of pain and intense pruritus, which eventually resulted in sudden death, was referred for necropsy. Postmortem examination showed thoracic and abdominal serum-sanguineous exudates, multifocal infiltrative renal masses, and similar tumors in the heart. Histopathology revealed midsize infiltrative neoplastic proliferation composed of round cells, sparse cytoplasm, and large hyperchromatic nuclei. Immunohistochemistry revealed CD3+ and CD20-immunoexpression. Histopathological and immunohistochemical findings confirmed the diagnosis of epitheliotropic lymphoma with cardiac and renal metastasis.

Visceral Marek's disease in white-peafowl (Pavo cristatus) Arq. Bras. Med. Vet. Zootec.
Blume,G.R.; Cardoso,S.P.; Oliveira,M.L.B.; Matiolli,M.P.; Gómez,S.Y.M.; Reis Júnior,J.L.; Sant'Ana,F.J.F.; Martins,N.R.S..
ABSTRACT Marek's disease (MD) is a lymphoproliferative disorder caused by Gallid herpesvirus 2 (MDV) that infects mainly domestic gallinaceous birds although wild birds may occasionally be affected. The current report describes the anatomopathological and molecular findings of a case of MD in a white-peafowl (Pavo cristatus). The signs included apathy, hyporexia, and diarrhea. Grossly, 0.5 to 1.5cm in diameter, yellow, soft nodules were observed in the skeletal muscle, lung, kidney, air sacs, small intestine, heart, ovary, ventriculus, and proventriculus. Microscopically, numerous atypical round neoplastic cells were noted. The molecular detection of MDV DNA was implemented to amplify part of the meq gene and products were sequenced for the phylogenetic...

Machado,L.H.A.; Palumbo,M.I.P.; Zahn,F.S.; Amorim,R.L.; Farias,M.R.; Werner,J.; Torres Neto,R.; Rodrigues,J.C.; Oliveira,F.C..
With the purpose of shedding light on some doubts in veterinary oncology, the present article intends to compare the results of histopathological and immunohistochemical examinations of unspecific round cell neoplasia, to realize immunophenotyping of canine lymphoma cases, to establish the T or B origin of neoplastic cells, and to determine the degree of proliferation and apoptosis of lymphomas by immunohistochemistry. Of 11 animals presenting immunohistochemical diagnosis of lymphoma, five had been diagnosed as Lymphoma by HE staining of histopathological slides and six had been classified as unspecific round cell neoplasia. All cases submitted to immunohistochemical examination were T-cell lymphomas. There was a positive correlation between cell...

Quantification of Treg cells in peripheral blood and lymph nodes of dogs with multicentric lymphoma Arq. Bras. Med. Vet. Zootec.
Anai,L.A.; Munhoz,T.D.; Semolin,L.M.S.; Reis Filho,N.P.; Terra,E.M.; Jark,P.C.; Fonseca,D.M.; Nogueira,A.F.S.; Tinucci-Costa,M.; Santana,A.E..
ABSTRACT Lymphoma is a malignant tumor characterized by cell proliferation of lymphoid origin and corresponds to 90% of all hematopoietic neoplasms of dogs. Regulatory T cells (Tregs) have been the target of many investigations in oncology due to their potential of down-regulating immune responses, as well as ensuring the maintenance of active mechanisms of tumor suppression. The aims of the present study were to compare the percentage of Tregs in peripheral blood between dogs with multicentric lymphoma and healthy animals, together with the percentage of Tregs in peripheral blood and lymph nodes of dogs with multicentric lymphoma. Twenty-six animals were enrolled in the study: 10 healthy dogs comprised the control group (CG) and 16 dogs with multicentric...

Bilateral peripheral facial palsy secondary to lymphoma in a patient with HIV/AIDS: a case report and literature review BJID
Sasaki,Maria das Graças; Leite,Patrícia G. B.; Leite,Andréa G. B.; Almeida,Sérgio Monteiro de.
Neurological complications represent one of the most important causes of morbidity and mortality in patients with HIV/AIDS. However, peripheral neuropathy comprises only 5% to 20% of the total neurological complications and facial nerve palsy, especially when it is bilateral, is a less common manifestation. Peripheral facial palsy has been considered as a possible neurological complication of the early stage of HIV infection but the number of reported cases in the literature is limited. Histological findings of nervous tissue in peripheral facial palsy at an early stage of HIV infection include a degenerative and not suppurative inflammatory process, but its etiology remains obscure. Peripheral facial palsy in the late stage of HIV infection is...

Fatal disseminated mucormycosis in a patient with mantle cell non-hodgkin's lymphoma: an autopsy case BJID
Alacacioglu,Inci; Kargi,Aydanur; Ozcan,Mehmet Ali; Piskin,Ozden; Solak,Cilem; Secil,Mustafa; Unlu,Mehtat; Demirkan,Fatih; Ozsan,Guner Hayri; Undar,Bulent.
A patient with mantle cell non-Hodgkin's lymphoma presented herself with fever, nausea, right upper quadrant pain on the 7th day of R-CHOP chemotherapy. After hospitalization with the suspicion of acute cholecystitis, she received antibiotherapy with G-CSF because of emerging neutropenia at the 10th day of chemotherapy. Abdominal computed tomography revealed small infarcts in the spleen and kidneys. The echymotic lesion which developed on her right lateral malleolus, became bullous in the following days and treated as ecthyma gangrenosum. Altough the patient was afebrile with a normal neutrophil count on the third day of antibiotherapy, she developed acute renal failure and deteriorated rapidly. The patient underwent hemodialysis but expired on the 10th...

AIDS-related lymphomas in Nigeria BJID
Bolarinwa,R.A.; Ndakotsu,M.A.; Oyekunle,A.A.; Salawu,L.; Akinola,N.O.; Durosinmi,M.A..
Aggressive non-Hodgkin's lymphoma (NHL), including primary central nervous system (CNS) lymphoma, lymphoblastic lymphoma and non-endemic Burkitt's lymphoma have been recognized as AIDS-defining cancers in most developed countries. However, HIV/AIDS epidemics appear not to have been associated with higher incidence of lymphomas in Africa. We therefore carried out this study to highlight the significance or otherwise of HIV/AIDS epidemics in the pathogenesis of lymphomas in a population of Nigerians with the disease. Since January 1993 to the present, all patients with haematologic cancers are routinely screened (following appropriate counseling) for HIV infection. Patients with a histological diagnosis of malignant chronic lymphoproliferative diseases...

Evaluation of ticarcillin/clavulanic acid versus ceftriaxone plus amikacin for fever and neutropenia in pediatric patients with leukemia and lymphoma BJID
Petrilli,Antonio Sérgio; Cypriano,Monica; Dantas,Lenice Silva; Lee,Lúcia Martino; Luisi,Maria Flávio Augusto Vercillo; Silva,Katia Veronica Torres B.; Pereira,Carlos Alberto Pires.
BACKGROUND: The empirical use of antibiotic treatments is widely accepted as a means to treat cancer patients in chemotherapy who have fever and neutropenia. Intravenous monotherapy, with broad spectrum antibiotics, of patients with a high risk of complications is a possible alternative. METHODS: We conducted a prospective open-label, randomized study of patients with lymphoma or leukemia who had fever and neutropenia during chemotherapy. Patients received either monotherapy with ticarcillin/clavulanic acid (T) or ceftriaxone plus amikacin (C+A). RESULTS: Seventy patients who presented 136 episodes were evaluated, 68 in each arm of the study. The mean neutrophil counts at admission were 217cells/mm³ (T) and 201cells/mm³ (C+A). The mean duration of...

New strategies in hematopoietic stem cell transplantation: G-CSF-mobilized unprocessed whole blood BJMBR
Dräger,A.M.; Ossenkoppele,G.J.; Jonkhoff,A.R.; Schuurhuis,G.J.; Huijgens,P.C..
Transplantation of mobilized peripheral blood stem cells (PBSC) for rescue of bone marrow function after high-dose chemo-/radiotherapy is widely used in hematologic malignancies and solid tumors. Mobilization of stem cells to the peripheral blood can be achieved by cytokine treatment of the patients. The main advantage of autologous PBSC transplantation over bone marrow transplantation is the faster recovery of neutrophil and platelet counts. The threshold number of PBSC required for adequate rescue of bone marrow is thought to be about 2 x 106 CD34+ cells/kg, if the stem cells are collected by leukapheresis and subsequently cryopreserved. We show that this critical number could be further reduced to as few as 0.2 x 106 cells/kg. In 30 patients with...

Malignant tumor affects the developmental pattern of feeding larvae of Chrysomya albiceps (Wiedemann) and Chrysomya putoria (Wiedemann) (Diptera: Calliphoridae) Neotropical Entomology
Carvalho,Lucila M.L. de; Palhares,Fortunato A.B.; Linhares,Arício X..
Larvae of Chrysomya albiceps (Wiedemann) and Chrysomya putoria (Wiedemann) were reared on liver tissues from a rabbit that had a malignant tumor in the thoracic cavity. Larval rearing of both blowfly species was conducted at ambient temperature. Larvae that fed on tissues from the rabbit with the tumor developed at significantly faster rates than those feeding on tissues from the control animal.
