Cutaneous fibropapillomas of green turtles (Chelonia mydas)

Hematological and histopathological evaluation of wildlife green turtles (Chelonia mydas) with and without fibropapilloma from the north coast of São Paulo State, Brazil

“…In histopathological evaluation, the characteristics observed were similar to those described in previous works (Jacobson et al 1989, Work et al 2004, Greenblatt et al 2005. Regarding the number of tumors, it appears that animals are usually affected by multiple formations.…”

“…Macroscopic studies were compatible with the existing on fibropapillomatosis (Jacobson et al 1989, Greenblatt et al 2005. Solitary or multiple tumors were found in all regions of the body, including lines of suture adjacent to the dermal shields.…”

“…Solitary or multiple tumors were found in all regions of the body, including lines of suture adjacent to the dermal shields. The formations are described by other authors in the same way in the turtles included in this work (Jacobson et al 1989, Norton et al 1990, Aguirre et al 1994, 1998, 2002, Brooks et al 1994, Adnyana et al 1997, Work et al 2004.…”

“…Fibropapillomas are benign tumors that can achieve 30cm of diameter (Lackovich et al 1999) and can involve the tegument of the fins, eyes, base of the tail, oral regions, cervical, inguinal, axillary, carapace and cloacal region (Jacobson et al 1989, Herbst 1994). The disease is characterized by the presence of internal and external tumors (Herbst 1994).…”

“…Before 1982, there was no register of FP in turtles captured in Florida and since then the number of cases has grown considerably (Jacobson et al 1989). In Brazil, the first report occurred in 1986 on the coast of Espírito Santo State and the prevalence was 15.41% according to data from 2000 to 2005.…”
