Registry of Tumors in Lower Animals.
A registry of tumors in lower animals has been established at the Smithsonian Institute for the purpose of aiding in the study of neoplasms among the lower animals. Nearly 50 countries have sent specimens for diagnosis and accessioning into the collection. Specimens registered represent the lower 99 percent of the animal kingdom, excluding birds and mammals. Not only were neoplasms included but also reference cases of diseases which may be easily confused with neoplastic disorders. A series of coral cases were considered to be significant as they are the most primitive animal yet found with neoplasms. A synopsis of these coral neoplasms was presented. The registry collected the specimens, and also gathered, abstracted, computerized and disseminated information to interested parties. Some recent cases were highlighted, including the evaluation of clams and fish exposed to harbor sediment found in Bridgeport, Connecticut; the exposure of rainbow trout to dioxins; and surveys in the Black River and the Cuyahoga River in Ohio, the Fox River in Wisconsin, and in waterways which have given evidence of liver cancer in brown bullhead. A discussion of the tumors in coral and characteristics of the tumors in fish followed.
