We report a 40-year-old Japanese man with a creeping eruption caused by a larva of the nematode suborder Spirurina type X. He had eaten raw small squid (hotaruika) 4 weeks before the serpiginous erythematous eruption appeared on his abdomen. Routine laboratory tests revealed only slight eosinophilia in his peripheral blood. Although we could not find the larva in an excised skin specimen, an indirect immunofluorescence test confirmed the presence of antibodies against larvae of the suborder Spirurina type X. We review 28 reported cases in Japan which showed that creeping eruption caused by larvae of the suborder Spirurina type X has the following clinical characteristics: an incubation time of 1-4 weeks; a migratory, well-defined, narrow, serpiginous erythematous eruption; and only slight peripheral blood eosinophilia. Excision of the advancing end of the track was curative in our patient.
