Linfoma cardíaco primário em cão

Lymphomas are malignant neoplasm characterized by proliferation of lymphocytes that originate primarily in lymphoid organ such as lymph nodes, liver, spleen and bone marrow. However the feature of continuous migration of lymphocytes in different organs, this tumor can develop in any organ. Although lymphoma is a very common hematopoietic neoplasm in dogs, cardiac location is rare. The diagnosis of primary cardiac lymphoma may be performed when there is involvement of the heart and/or the pericardium without evidence of involvement in other organs. In veterinary medicine there are few reports on the diagnosis, treatment and prognosis of cardiac lymphoma. Therefore, the purpose of this report is to describe a case of cardiac lymphoma in which the patient responded favorably to chemotherapy employee with disease-free interval of 19 months and highlight the importance of including this neoplasm in the differential diagnosis of diseases that affect the cardiovascular system.

Proliferating cell nuclear antigen immunoreaction in adrenal-tumors

Aims mid background: We studied, retrospectively, 33 cases of adrenal tumors of children at the Pediatric Endocrinology Unit, Children's Institute, Sao Paulo State University Medical School, from 1975 to 1993. Ail patients had at least 2 years of follow-up with a few exceptions. Methods: Clinical follow-up data were correlated with histopathologic review, laboratory data and cell kinetic evaluation (based on detection of proliferating cell nuclear antigens). Results: With one exception, all the patients had presented signs of androgen production and had high levels of dehydro-epiandrosterone-sulfate. Tumor weight evaluation represented a good parameter of neoplasm evolution: of 19 cases weighing less than 250 g, 17 had no evidence of disease after surgery, and 2 had an unfavorable prognosis. Of 14 cases weighing more than 250 g, only 1 had no evidence of disease and 13 had an unfavorable evolution. Conclusions: Proliferating cell nuclear antigen (PCNA) was not helpful to evaluate adrenal neoplasm evolution: our study did not show any correlation between PCNA score and prognosis.

Transplante de medula óssea para suporte de células tronco hematopoiéticas em cães acometidos por linfoma

Lymphoma represents the most prevalent hematopoietic malignancy in small animal medicine. It is highly responsible to chemotherapy and therefore several protocols are used as therapeutic tools. For that reason, the bone marrow transplantation, enshrined in human medicine through initial trial in canine patients, has increasingly become the focus of studies in order to make it a reality also in veterinary medicine. First, the treatment with the chosen chemotherapy protocol is made. As complete remission of lymphoma is observed, it must be initiated the bone marrow harvesting. The obtained material is subjected to the processes of erythrocyte depletion, plasma depletion, cryoprotectants addition, total nuclear cells counting, hematopoietic progenitor quantification, analysis of cell viability and freezing. Following that, with radiotherapy or application of cyclophosphamide, the conditioning phase of the patient who is receiving the transplantation is carried out. The bags containing hematopoietic stem cells are then thawed and transplanted into the receptor organism. Support with hematopoietic stem cells allows the use of lethal doses of chemotherapy or radiotherapy and has been shown to considerably raise the disease remission time and survival rate of the canine patients

Importância do exame laboratorial no diagnóstico de linfoma em cães e gatos

Lymphoma is a cancer originating in solid hematopoietic tissue and is one of the most common tumors in dogs and cats. Usually the diagnosis is made late, when the disease is at an advanced stage, reducing the success of treatment, affecting the prognosis. Therefore, early diagnosis is the best tool to combat this increasingly common disease in veterinary medicine. Due to the diversity of presentations and forms of the disease, clinical signs are nonspecific and varied making the use of laboratory testing essential to lymphoma diagnosis in order of establishing the most appropriate treatment as quickly as possible, giving the patient a longer survival rate

Signos neurológicos asociados a pacientes caninos con linfoma

Cancer alters the structure or functions of adjacent organs with their sole presence, and subsequent clinical manifestations, but can also cause harmful effects in distant organs. These clinical changes induced by non-invasive tumor action are of great clinical diversity and are known as paraneoplastic syndromes. This paper describes four cases of canine patients with neurological disorders associated to generalized superficial lymphadenopathy.
