visceral larva migrans

larva

[lahr´vah] (pl. lar´vae) (L.) 1. an independent, immature stage in the life cycle of an animal, in which it is markedly unlike the parent and must undergo changes in form and size to reach the adult stage.2. something that resembles such an immature animal.larva cur´rens a rapidly progressive eruption" >creeping eruption caused by autoinoculation of larvae of Strongyloides stercoralis that migrate to and mature at the anus in intestinal infections with the parasite.cutaneous larva mi´grans (larva mi´grans) a convoluted threadlike skin eruption that appears to migrate, caused by the burrowing beneath the skin of roundworm larvae, particularly of the species Ancylostoma; similar lesions are caused by the larvae of botflies" >botflies. Called also creeping eruption.ocular larva migrans infection of the eye with larvae of the roundworm Toxocara canis or T. cati, which may lodge in the choroid or retina or migrate to the vitreous; on the death of the larvae, a granulomatous inflammation occurs, the lesion varying from a translucent elevation of the retina to massive retinal detachment and pseudoglioma.visceral larva migrans a condition due to prolonged migration by the skin larvae of animal nematodes in human tissue other than skin; commonly caused by larvae of the roundworms Toxocara canis and T. cati.

vis·cer·al lar·va mi·grans

a disease, chiefly of children, caused by ingestion of infective ova of Toxocara canis, less commonly by other ascarid nematodes not adapted to humans, the larvae of which hatch in the intestine, penetrate the gut wall, and wander in the viscera (chiefly the liver) for periods of up to 18-24 months; may be asymptomatic or may be marked by hepatomegaly (with granulomatous lesions caused by encapsulated larvae in the enlarged liver), pulmonary infiltration, fever, cough, hyperglobulinemia, and sustained high eosinophilia.

visceral larva migrans

Parasitology A condition of children infected by GI tract parasites of dogs–Toxocara canis or cats–T cati; after ingestion, eggs hatch into larvae in the intestine, burrow through the GI wall and migrate elsewhere–eg, liver, lung, brain, eye, and other organs, causing inflammation and tissue damage as they migrate Clinical Self-limited Sx–eg, fever, lung complaints–cough and wheezing, seizures, hive-like rashes, ↓ visual acuity, periorbital edema, strabismus. See Toxocara spp.
