In south Louisiana, a dermatitis has been recognized called "nutria itch," "marsh itch," or "creeping eruption." The possible link between the large number of nutrias and the occurrence of a severe pruriginous rash hours after people have been in water or close to a swamp has been noted.1-3
A 12-year-old boy and his 68-year-old grandfather developed diarrhea and an intensely pruritic rash on their trunks and extremities after working in mud next to a marsh populated with nutrias. After 2 weeks of severe pruritus and no improvement, they sought medical attention. Results of their physical examination showed a maculopapular erythematous rash that involved the chest and extremities, but the grandfather's rash was more severe
