Larva Migrans (Larva Migrans Syndrome)

Larva migrans or creeping eruption is an infestation of the skin by a nematode larvae. These worms normally parasitize the intestine of other animal species. The nematode cannot complete its life cycle in man. As the worm migrates in the epidermis, it produces a characteristic lesion. They lack the capacity to cross the basal layer in the epidermis due to lack of essential collagenases or due to the host immune response (Actas Dermosif 1987; 78:751-52).
