Following the previous reports (Report I-VI), histopathological studies were conducted in avian leukosis of the erythrocyte and granulocyte series. Among the 1, 904 cases used in the previous report (Report VI), 16 cases under the histological diagnosis of this disease were used as the material for this study. For an outline of the histopathological change in avian leukosis of erythrocyte series, see Figs. 1-18. As a rule, throughout the five cases studied, the appearance of, abnormal cells in the tissue took place intravascularly. The degree of maturity does not always show regularity according to the tissue of individual animal. As for histological change, diffuse and microscopic changes were the characteristic changes. However, in one case (No. 3) macroscopically visible tumors were also noted between the muscles and subcutaneus tissues. For an outline of histopathological change in avian leukosis of granulocyte series, see Figs. 19-44. In 11 cases examined, it should. be noted that immature cells of the granulocyte series were congested within the blood vessel, and lesions were formed in the interstitial tissue, especially in the perivascular region and within the lymphatic tissue. Most of the abnormal cells were immature cells of the granulocyte series in the later stage with eosinophilic granules in the cytoplasm. The histological picture consisted of small lesions containing these cells. In some cases macroscopically visible tumor formations were confirmed between muscles, serosa, around large blood vessels and other connective tissues (Nos. 7, 14, 16 etc.). In summary of these findings, They are essentially in agreement with the past reports on the histopathological picture of avian leukosis of erythrocyte and granulocyte series. The histopathological characteristics of these two diseases, the histogenetically main involvment of the so-called hematopoietic organs in leukosis of erythrocyte series and the lymphatic tissue in leukosis of granulocyte series as the basal tissue deserves emphasis.
