title: [Morphological analysis of spontaneous hemoblastoses in dogs and cats].
abstract: Information of the frequency and morphological characteristics of spontaneous hemoblastoses in dogs and cats observed in 1966-1978 are presented. Hemoblastoses were diagnosed in 90 dogs and 12 cats. Lymphoproliferative diseases were most frequent: lymphosarcomas (80 cases) and lymphocytic leukemias (11 cases). Ten dogs had mastocytomas and one--myeloid leukemia. The cell composition of the organs and tissues involved permitted to distinguish 3 cellular variants of lymphosarcoma: poorly differentiated, lymphoblastic, and prolymphocytic; in both species the poorly differentiated type of lymphosarcoma was predominant (47 cases). It is recommended to use spontaneous hemoblastoses of dogs and cats as an experimental model for investigations of the pathogenesis and therapy of human leukemias.
