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. |

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... |

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... |

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... |

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... |

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... |

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... |
