The infectious nature of stomatopapilloma has been proposed for many years, and the experience with eel husbandry suggests the recurrence of the disease in impounded populations. The seasonal incidence of this papilloma is reminiscent of many fish diseases of viral etiology. Viral agents have been isolated from eels with and without stomatopapilloma. However, attempts to produce tumors by inoculation of eels with virus or extracts from diseased eels have been unsuccessful. A slow or latent virus infection has been suggested, the activation of which could result from many factors. The effects of environment and environmental quality cannot be dismissed, because many substances introduced into the environment are carcinogenic. Although such substances have been indicated as causes of some fish neoplasms, in eels their role in tumor formation or in potential latent virus activation is not known. Investigations to date have resulted in few definitive conclusions. At present, neither viruses nor pollutants show an explicit causal relationship to stomatopapilloma. It is important to note that stomatopapilloma has not been recognized in Japan or the United States, both of which are heavily industrialized. This lack of recognition may indicate a unique situation in Europe that involves both virus and pollution. Further evaluation of the multifaceted interaction of biologic and environmental variables is required for an understanding of the etiology of stomatopapilloma of eel.
