Medical Care

The disease usually is self-limited, with spontaneous cure after several weeks; treatment may hasten resolution of symptoms. 

As CLM is self-limiting, it will resolve within several weeks. However, treatment with antihelminthics may considered to shorten duration of symptoms. [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.

Consultations

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

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.

Prevention

Prevention of cutaneous larva migrans (CLM) is critical.

Advise patients to avoid sitting, lying, or walking barefoot on wet soil or sand.

Advise individuals to cover the ground with an impenetrable material when sitting or lying.

Pets should be dewormed.

Beaches that allow cats and dogs should be avoided.
