Asymptomatic eosinophilia due to gnathostomiasis.

The diagnosis of gnathostomiasis typically includes a triad of eosinophilia, migratory skin lesions, and exposure risk. The cutaneous manifestations are protean yet often involve intermittent migratory swellings and creeping skin eruptions with abscesses or nodules, which vary in onset and duration. We report the first case of gnathostomiasis presenting as fever and eosinophilia without cutaneous migratory and internal organ involvement.
