Cutaneous larva migrans (CLM) is a cutaneous lesion produced by percutaneous penetration and migration of larvae of various nematode parasites, characterized by erythematous, serpiginous, papular, or vesicular linear lesions corresponding to the movements of the larvae beneath the skin.
Larvae remain viable in soil/sand for several weeks.
