Leucemia canina: casos diagnosticados no período de 2003 a 2006

Abstract

Leukemia is characterized by the presence of malignant neoplastic cells of hemolymphatic origin in the blood and / or bone marrow. They can be classified into lymphoblastic or myeloblastic, being divided into acute or chronic according to the predominant cell characteristic and subclassified according to the cell type found. As a definitive diagnosis, in addition to histopathological examination, other techniques such as immunohistochemistry, enzymatic cytochemistry and immunophenotyping can be used, which are more specific and effective for the classification of leukemias. Approximately 30% of canine leukemias are lymphoid. This study aimed to survey the cases of leukemia in dogs diagnosed by the Pathology Laboratory of the Faculty of Veterinary Medicine of São João da Boa Vista -SP - UNIFEOB, in the period from 2003 to 2006, totaling 10 cases of leukemia of origin lymphoid and three cases presenting foci of lymphadenization.
