An Autopsy Case of Pemphigus Vulgaris Complicating a Fatal Strongyloidiasis

An autopsy case of fatal strongyloidiasis in a patient with pemphigus vulgaris receiving long‐term administration of corticosteroids was presented. There might exist a subclinical stage of 26 years between the acquisition of infection and the appearance of its severe symptoms. It is suggested that the long‐term administration of corticosteroids and debilitating diseases increase the pathogenecity of Strongyloides stercoralis by autoinfection, and that fatal strongyloidiasis could be a possible complication of treatment with corticosteroids.
