DISSEMINATED STRONGYLOIDIASIS

Abstract
Strongyloidiasis is a parasitic infestation caused by the helminth Strongyloides stercoralis. It is essentially gastrointestinal and in general asymptomatic but can sometimes present with skin signs. Immunocompromised patients can develop the disseminated form of the disease due to the parasite's opportunistic behavior, as in cases of coinfection by the human T-lymphotropic type 1 virus (HTLV-1). This article presents a case of a patient infected with HTLV-I and Strongyloides stercoralis who developed the disseminated form. There were purpuric reticulated periumbilical lesions as well as vibices on the patient's flanks. Histopathologic exam of a skin lesion revealed the presence of larvae in the deep reticular dermis. We emphasize the relevance of awareness regarding interaction between HTLV-1 and strongyloidiasis, besides identification of the cutaneous manifestations of the disease to reach an appropriate therapeutic diagnosis.
