title: Erythremic myelosis (AML6er) in a cat.
abstract: A 4-year-old male European domestic cat was presented with dysorexia, weakness and depression. Normocytic normochromic non-regenerative anaemia, leucopaenia and thrombocytopenia were detected. Rubriblasts were detected both in the blood and in the bone marrow. Tests of blood chemistry revealed no alterations of renal and hepatic function and a positive reaction to FeLV antigen was detected in the cat's serum. Neoplastic cells did not show positive to cytochemical reactions against granulocytes, monocytes and lymphocytes. According to haematological and bone marrow cytological findings, a diagnosis of erythremic myelosis (AML6er) was made. Histopathology showed extramedullary haematopoiesis in the liver, spleen, kidney and lymph nodes and chronic nephropathy and degenerative signs in the liver.
