title: Dermatitis due to larvae of a soil nematode, Pelodera strongyloides.
abstract: A 6-month-old infant girl was seen because of failure to thrive and hyperpigmented papulonodules on the lower abdomen and thighs. Results of skin biopsy demonstrated dauer larvae of a soil nematode, Pelodera strongyloides, in the dermis. This is the second documented episode of human dermatitis due to this nematode, which more often invades the skin of dogs, cattle, horses, and sheep.
