Cutaneous larva migrans (CLM) is characterized as creeping eruption/serpiginous erythema and/or mobile erythematous induration on the skin. In Japan, Gnathostoma spp. are the most well known pathogens causing CLM, especially the creeping eruption type. Recently, Spirurina type X larvae have been added to the list of causative agents for creeping eruption in Japan. Here we report one confirmed and 6 suspected cases of creeping eruption caused by infection with dog hookworm larvae. The patients were assumed to have been infected overseas. Dog hookworms such as Ancylostoma caninum and A. brasiliense should be considered as possible causative agents for creeping eruption, especially when the patients have a history of travelling overseas.
