Twenty-eight cases of feline lymphosarcomatosis encountered in the Tokyo area from 1964 to 1972 were studied pathologically. According to localization of tumor masses, they were divided into, the thoracic, abdominal, and mixed forms. Eighteen cases of the thoracic form had a tumor mass 5 cm or over in diameter in the anterior part of the mediastinum in the thorax. In this form, tumors appearing in other organs never exceeded 2 cm in diameter. In 8 cases of the abdominal form, tumor masses 5 to 10 cm in diameter were found in the liver, spleen, kidney, duodenum, jejunum, pancreas, spermatic cord and lymph nodes. The mixed form comprising only 2 cascs had tumor masses more than 5 cm in diameter in the mediastinum, as well as in the renal and jejunal lymph nodes. Histologically, the tumor consisted mainly of large immature lymphoid cells with a distinct nucleolus and relatively poor cytoplasm in all the cases, except two which had tumors consisting predominantly of small mature lymphoid cells. The so-called starry-sky pattern was marked in either affected lymph nodes or tumor masses of the mediastinum. In any case there was no marked proliferation of argyrophile fibers.
