[Foodborne dermatosis after traveling: gnathostomiasis]

[Article in Spanish]


We describe a case of a 32-year-old man, resident in Buenos Aires, with dermatologic manifestations compatible with gnathostomiasis. The patient had traveled to Colombia in the month prior to the onset of symptoms. There, he repeatedly ate ceviche (raw fish marinated in lemon juice). He presented with an erythematous migratory panniculitis accompanied by eosinophilia. He underwent skin biopsy of a lesion and pathological diagnosis was "eosinophilic panniculitis". The triad of migratory panniculitis, eosinophilia and consume of raw fish during the trip to Colombia was suggestive of gnathostomiasis. Ivermectin treatment started out with good initial response but subsequent relapse. We performed a new treatment with the same drug with good results and no relapses during three years of follow up. The dermatological disease is common upon return from a trip, and is the third leading cause of morbidity in travelers. It is very important to recognize cutaneous manifestations of disease as many of them are potentially serious and may compromise the patient's life if not promptly diagnosed and treated.

Keywords: dermatoses; eosinophilia; gnathostomiasis; migrant larvae.
