A retrospective study was conducted on partial cases of sheep pulmonary ade- nomatosis (SPA)from surveys in Xinjiang from 1955 through 1980. The coexistence of SPA and ovine progressive pneumonia(OPP)or maedi lesions was found in 5 out of 31 SPA lung lesions; in 12 mediastinal lymph nodes examined the adenomatous metastases were only found in 1 case with the metastatic rate of 8. 3%. The ultrastructure of 6 cases indicated that the adenomatous cell originated from type Ⅱ pneumocytes,and viruses budded from the sur- face of tuumor cells in 2 of 6 cases and the virions were morphologically similar to retrovirus.
