Chronic myeloid leukemia, also known as chronic neutrophilic leukemia, is characterized by a clonal expansion of granulocytes in peripheral blood and bone marrow (VALLI, 2002), as this neoplastic proliferation of the neutrophilic series can occur concomitantly with that of eosinophils...
In cats, a form of leukemia exists that is contagious between cats. This is the feline leukemia virus (FeLV).Other leukemias (involving nonlymphocytic blood cells, such as neutrophilic leukemia, erythroleukemia, and others) are much less common than those described above.
The most common cause of myelofibrosis in dogs is precursor-directed immune-mediated anemia and in cats is myelodysplastic syndrome or acute myeloid leukemia (very different prognoses for dogs versus cats).
