Abstract
Pathological investigation was carried out on 10 cases of lymphosarcoma in swine. Cytologically, neoplastic cells in these cases presented essentially the same morphological characteristics as lymphocytes. Neoplastic lesions were recognizable predominantly in lymph nodes, liver, spleen, kidney and urinary bladder, and additionally in many other organs macroscopically or histologically. They were remarkable in tonsil, genital organs, bone marrow, nervous tissue, pancreas, adrenal, hypophysis, tongue, submaxillary gland and gallbladder. Their histogenesis was suggested to consist in the accumulation of neoplastic cells throughout perivascular areas, judging from the character of these cells.
