HE staining of different tumor tissues.. HE staining of the suspected tumor tissue showed that normal tissue and organ structures were destroyed, and a large number of lymphocytes or myeloid tumor cells infiltrated the tumor tissue. The cells were large and round, with abundant cytoplasm and obvious eosinophilic granules, as well as a small number of infiltrating monocytes and blood cells. Moreover, cells atdifferent stages of differentiation were observed and were round, conical, spindle and long fiber types. The colored particles in some cells had no autolysis. In summary, the suspected tumor tissues collected were confirmed to be tumors caused by chronic transformed ALV-J.
