Medical Care

Treatment of cutaneous larva migrans (CLM) is anthelminthics, with pruritus resolving within 24-72 hours and serpiginous tracts resolving within 7-10 days. [15, 16]

Antihistamines and topical corticosteroids can be used in conjunction with anthelminthics for symptomatic relief of pruritus.

Oral antibiotics are used if secondary impetiginization or cellulitis is present.


Surgical Care

Prior to the availability of anthelminthics, treatment by cryosurgery with liquid nitrogen, ethyl chloride spray, or carbon dioxide slush was effective in 60-70% of individuals with CLM.

Cryosurgery is painful and often requires multiple treatments. Cryosurgery at the leading edge of the track was imprecise because the migrating larvae are usually located several centimeters beyond this point.



Consultation with a dermatologist, infectious diseases specialist, or both may be appropriate.
