[Often unrecognized cutaneous manifestations of strongyloidosis: linear dermatitis or larva currens (author's transl)].

The linear dermatitis of "larva currens" is a typical manifestation of strongyliasis, however is generally too unrecognized. It is observed in about 7% of cases, more frequent in white race. Due to the migration of Strongyloides larvae in epidermis of sensitized person, it appears in form of rectilinear urticaria from 10--30 cm, developed from 12--48 hours and disappeared without leaving any trace. It can appear at any place of the body, sometimes in many places simultaneously. The total duration of the evolution similiar to that of strongyliasis can be developed during a many tenth of years. In reality the differential diagnosis is easy with filariasis (loa-loa) and specially with cutaneous larva migrans (ankylostomiasis, creeping eruption, larbish). The thiabendazole cures the strongyliasis nad its cutaneous manifestations in 85% of cases with a single oral dose of 6 tablets 6 x 250 mg).
