Abstract

Bone marrow cytology in Wright or Wright Giemsa stained smears from 181 feline patients were evaluated according to recently published criteria by the animal leukaemia study group for classification of acute] myeloid leukaemas (AML) and myelodysplastic syndrome (MDS). AML was recognised in 107 (59.1%) and MDS in 39 (21.5%) cats. The frequency of acute myeloblastic leukaemia (M1 and M2 combined) was high (30.9%), erythroleukaemia (M6 and M6-Er combined) was relatively less frequent (17.1%), and acute undifferentiated leukaemia (AUL), acute monoblastic leukaemia (M5) and acute myelomonocytic leukaemia (M4) were less common, each with an incidence of less than 5.0%. Most of the M1 cats had greater than 70.0% blast cells in bone marrow compared to only a few of the M2 cats. Some blast cells in occasional AUL cats showed cytoplasmic differentiation to either erythroid or myeloid lineage or rarely to both. Type I (classical) myeloblasts predominated in all Ml cats, but occasional type II myeloblasts were seen in some cats and a few cats had some type III myeloblasts. Rubriblasts were prominent in most of the M6-Er cats.
