[Strongyloidosis. I. Specific and nonspecific skin lesions].

Specific, recurrent, tortuous or linear serpiginicus urticarial rash and nonspecific, stationary urticarial skin lesions appearing during infection with Strongyloides stercoralis and concomitant clinical manifestations in human were presented. Pathognomic form of larva currens in primary infection with S. stercoralis and in already allergic host during exo-autoinfection of the parasite, and similar skin lesions appearing during the endo-autoinfection but without the presence of S. stercoralis larvae in skin were described. Nonspecific urticarias were set against the pathognostic lesions.
