Cutaneous Larva Migrans.

International travel and increasingly exotic diets have resulted in an increase in cases of cutaneous larva migrans in industrialized countries. A broader spectrum of clinical presentation and complications of cutaneous larva migrans is recognized by clinicians. A new syndrome, eosinophilic enteritis, has been described in Australia and may be more widespread as new diagnostic tests are used more widely. Other causes of cutaneous migration, such as gnathostomiasis and sparganosis, should be considered, and a recent outbreak of gnathostomiasis in Mexico suggests that clinicians must be alert to these unusual infections arising in patients outside their traditional distribution.
