Sci. 2008 9 1 109-111 JOURNAL OF Short Communication Veterinary Science Acute monoblastic leukemia in a FeLV-positive cat Kreangsak Prihirunkit1 Nual-Anong Narkkong2 Suntaree Apibal3 Department of Pathology Faculty of Veterinary Medicine Kasetsart University Bangkok-10900 Thailand 2Central Instrumentation Unit Faculty of Science Mahasarakarm University Mahasarakarm-44150 Thailand 3Department of Pathology Faculty of Medicine Ramathibodi Hospital Mahidol University Bangkok-10400 Thailand A male domestic short hair cat was brought to the Veterinary Medical Teaching Hospital Kasetsart University with signs of severe anemia depression and general lymph node enlargement. Complete blood count revealed leukocytosis and massive undifferentiated blasts. Testing for antibodies specific to feline leukemia virus FeLV was positive and FeLV nucleic acid was confirmed by nested polymerase chain reaction. Base on cytochemistry and ultrastructure the cat was diagnosed with acute mono-blastic leukemia. Keywords cat cytochemistry FeLV monoblastic leukemia ultrastructure Feline leukemia virus FeLV is a retrovirus that causes a wide range of proliferative diseases in cats including lymphoid and myeloid leukemia 6 . Acute myeloid leukemia may be misinterpreted as acute lymphoid leukemia if the blast cells are classified using only Romanowsky stained smears 10 . Cytochemical staining has been employed to aid in the differentiation of acute leukemias 2 . Assessment of cell ultrastructure by transmission TEM or scanning electron microscope SEM has also been used to enhance the magnitude of cell identification especially with poorly differentiated cells 1 . Although FeLV is a common infectious disease in young cats no clinical cases ofacute monoblastic leukemia in FeLV-infected cats in Thailand have been reported previously. In the present report a case of acute monoblastic leukemia in a FeLV-positive cat is described. A male domestic short hair cat was .
