A 6-year (1985–1990) retrospective survey of raccoons with canine distemper infection and an outbreak of the disease in 1988 on South Island, South Carolina, are described. During this epizootic, 3 male raccoons with the clinical disease had gross testicular lesions that, on histopathologic examination, revealed severe diffuse degeneration and mineralization of seminiferous tubules. The testicular pathology of canine distemper in raccoons has not been previously reported.
