Abstract: | Myelofibrosis has been reported infrequently in dogs. The pathological features of three dogs with this disease are described. All three animals were presented clinically with non-regenerative anaemia. In two dogs, the neoplastic disorder was unaccompanied by other myeloproliferative disease and was characterized histologically by extensive replacement of normal bone marrow elements by proliferating reticulum cells and myeloid metaplasia of the enlarged liver and spleen. In one animal, focal myeloid metaplasia were also present in the lungs. In the third dog, myelofibrosis was accompanied by erythraemic myelosis and in this animal immature erythroid cells were present in blood, bone marrow, liver and spleen. |
