Dioctophyme larva in the subcutaneous tissues of a woman in Ohio

A nematode larva undistinguishable from Dioctophyme renale was found in the subcutaneous tissues of the abdomen of a 23-year-old woman from Ohio. This is the third case of Dioctophyme larva reported in humans. Although it is not known how the infection was acquired, we suggest that ingestion of raw fish was the probable source. We further hypothesize that such a larva could eventually migrate to the kidney and grow to the adult state.
