Relatively few neoplasms in reptiles have been reported. Although most of these were in snakes, Kast (1967) could find only 25 cases of snake tumors sufficiently described for review, since 1885.The first description of a neoplasm of the reptilian hematopoietic system appeared in 1969, when Frank and Schepky reported a metastasizing lymphosarcoma in an anaconda, Eunectes muriniis. In the preceding year Cowan ( I 968) mentioned but did not describe lymphothickness were prepared and stained with hemalum-eosin, Weigert-Van Gieson-elastica, and Gomori reticulum stains.Histologic sections and autopsy records of these cases are filed as accession numbers 291 and 461 respectively, in the Registry of Tumors in Lower Animals, Smithsonian Institution, Washington, D. C.
