CUTANEOUS LARVA MIGRANS
What is it?
Cutaneous larva migrans (CLM) is the most common tropically acquired dermatosis whose earliest description dates back more than 100 years. Cutaneous larva migrans manifests as an erythematous, serpiginous, pruritic, cutaneous eruption caused by accidental percutaneous penetration and subsequent migration of larvae of various nematode parasites.
Differential diagnosis
Tinea pedis
Allergic contact dermatits
Epidermal dermatophytosis
Erythema migrans of Lyme borreliosis
Migratory myiasis
Photoallergic dermatitis
Larva currens caused by Strongyloides stercoralis
Treatment
Although CLM will resolve spontaneously in 2 - 8 weeks in most instances, treatment has the benefit of relieving symptoms and helping
to avoid bacterial superinfection. Oral treatment options include ivermectin, preferred, and albendazole. Topical agents, such as thiobendazole, can be tried, but are often difficult to locate.
