HISTOGENETICAL STUDIES OF ABDOMINAL CANCERS IN THE FOWL

Abstract

As is known, various kinds of interesting tumours occur in the fowl. At autopsy of 3150 hens, 350 cases of leiomyoma, 1 case of rhabdomyoma, 3 cases of fibroma, 4 cases of lipoma, 7 cases of sarcoma, 8 cases of lymphoma, 1 case of malignant adenoma, 3 cases of cystoma and 37 cases of intra-abdominal carcinoma were found. In 270 cocks, however, only 1 case of sarcoma was found.44 cases of carcinoma, including 7 cases which were collected from poulterers, have been studied histogenetically; it has been shown that 16 cases were resulted from the cells of oviduct gland, 1 case from the mucous membrane of oviduct, 9 cases from the paraovaries, 6 cases from the follicular cells of ovary, 1 case from the cells of the seminiferous tubule of the ovary, 1 case from the peritoneal ep thelium, 6 cases from the intestinal mucous membrane, 1 case from the epithelial cells of the bile duct duct and 3 cases from the adrenal cortex.
