Larva currens represents cutaneous infection by the Strongyloides stercoralis larvae.


Linear, red, urticarial, inflammatory lesions that migrate rapidly are :characteristic (racing larvae).


Often, the larvae are not seen in the biopsy specimens. The diagnosis may be confirmed by stool analysis for Strongyloides larvae.


Typically, oral thiabendazole or albendazole are recommended although each therapy ::has disadvantages. Oral ivermectin (e.g. 12-24 mg. as ia single dose or repeated in 24 hours) has been reported to be successful. The absence of cutaneous symptoms, a normal blood count, a normal eosinophil count and a negative stool test indicate successful treatment.
