Cutaneous larva migrans (CLM), or creeping eruption, often affects the feet because people commonly walk barefoot in areas where the parasite is prevalent, such as beaches and sandy soil. This increases the likelihood of exposed skin coming into contact with contaminated soil or sand, where hookworm larvae reside
Cutaneous larva migrans (CLM), also known as creeping eruption) is a characteristic eruption that is caused by penetration and migration in the skin of nematode larvae species Ancylostoma. In the US, Acnylostoma caninum or A. braziliensis (dog or cat hookworm) is common. Walking barefoot on sand or soil contaminated with dog or cat feces allows the hookworm larvae to penetrated the skin.
An inflamed, red, linear, worm-shaped lesion is seen. The foot is a common location.
