Hematopoietic tumors are associated with diagnostic and therapeutic challenges and a poor prognosis. Furthermore, their pathophysiology in dogs is not well understood. Chronic lymphocytic leukemia has been rarely reported in golden retrievers, perhaps due to difficulties in diagnosis and care. An 8-year-old spayed female golden retriever was referred to our hospital with a 2-month history of fatigue, weakness, and selective appetite. The dog was diagnosed with chronic lymphocytic leukemia based on blood smear evaluation. despite treatment, the dog deteriorated and the owners opted for euthanasia. Histopathological examination revealed atypical lymphocytes in the spleen, extramedullary hematopoiesis in the spleen and liver, bone marrow depletion, moderate neutrophilic myocarditis, and acute renal tubular necrosis. In an immunohistochemical panel, cells in the spleen and bone marrow were positive for anti-CD20, anti-CD45, anti-CD3, anti-IBA-1, anti-Ki67, anti-MUM-1, and anti-PAX-5. In conclusion, the leukemia diagnosis was confirmed through reactive histiocytosis, marked extramedullary hematopoiesis, and other clinical and laboratory findings. Herein, we report a case of chronic lymphocytic leukemia in a female dog with clinical, laboratory, and necroscopy findings.

Oil palm (Elaeis guineensis Jacq.) is one of the agricultural crops with the greatest potentialfor vegetable oil production in Brazil. However, a disease of unknown etiology popularlyknown as Fatal Yellowin (FY) has caused damage to Brazilian farmers particularly in theeastern region of the Amazon. So, the objective of this study was to evaluate the spatialdependence of FY on three oil palm genotypes, grown for many years in an organic produc-tion system in the Amazon region. The study area had 4104 ha, divided into 139 plots. Ineach plot, the monthly incidence of disease was monitored forming a database. The num-ber of diseased plants per year, number of accumulated diseased plants, number of dis-eased plants per hectare, growth rate of diseased plants and incidence of accumulateddisease were evaluated. The results indicated spatial distribution of the variables adjustedto the gaussian, spherical and exponential models, with predominance of the first *** increases the purpose that FY is caused by biotic factors. The highest range achievedin the study was 2929 m indicating the susceptibility of the tested genotypes. Some plotsclose to the river had the highest incidence of the disease on the study, probably associatedwith higher soil moisture.
