In order to describe the biology and life cycle of Gnathostoma nematodes; and the epidemiology, clinical manifestations, diagnosis, management, and prevention of human gnathostomiasis, Internet search engines, including PubMed, Medline, Ovid, Google[R], and Google Scholar[R], were queried with the key medical subject heading (MESH) words, "infections, helminthic; Helminthiasis, gnathosomiasis, neurognathostomiasis; nematode parasites, Gnathostoma species." Case reports, case series, epidemiological investigations, and laboratory studies were reviewed; high-risk behaviors for gnathostomiasis were identified, and human cases of gnathostomiasis were stratified as cutaneous gnathostomiasis, visceral gnathostomiasis, neurognathostomiasis, and ocular gnathostomiasis.
Nematode species infecting the skin include Gnathostoma and the filarial species, Loa loa, Onchocerca volvulus, Mansonella streptocerca and Dirofilaria spp [3].

The most common nematodes to consider include Strongyloides stercoralis as part of a hyperinfection syndrome, Toxocara species or less commonly Baylisascaris species as agents of visceral larva migrans, or other nematode worms that may involve the CNS such as Angiostrongylus and Gnathostoma species.
(1) They can be divided into intestinal and tissue-dwelling roundworms, and further into those parasitic to humans only or zoonotic infections, where the adult worms parasitise animals and humans are accidental hosts (Toxocara canis, Angiostrongylus species, Gnathostoma species, and Trichinella spiralis).
