Resumo: | Eleven juvenile green turtles (Chelonia mydas) from Atlantic Ocean, Brazil, with multiple cutaneous papillomatosis were examined. Histologically, the papillomas exhibit stromal hyperplasia proliferation and epithelial proliferation. The epithelial cells had nuclear changes suggestive of viral infection and severe nuclear pleomorphism. A large nuclear halo was present in the cases of epithelial proliferation; in these cells, nuclear features were frequently dyscariotic, without inclusion. All fibropapillomas examined were negative for papillomavirus group-specific antigens (BPV) and herpesvirus group-specific antigens (HSV1 / HSV2) by the peroxidase-antiperoxidase technique. Electronic microscopy investigation was negative for papillomaviruses and herpes-viruses particles.
