cutaneous larva migrans

1. larva migrans in the skin, characterized by thin, curving, pruritic lines corresponding to the subcutaneous movements of the parasitic larvae. The usual cause is the cat and dog hookworm, Ancylostoma braziliense, which burrow beneath the skin but cannot complete their migration to the intestine. Called also ox-warble or sandworm disease and creeping eruption. 2. a similar condition caused by other parasites, such as any of various nematodes (see gnathostomiasis) or insect larvae (see hypodermiasis and cutaneous myiasis).
