Strongyloidiasis hyperinfection in a patient with a history of systemic lupus erythematosus.

Strongyloidiasis is a parasitic disease caused by Strongyloides stercoralis, a nematode predominately endemic to tropical and subtropical regions, such as Southeast Asia. Autoinfection enables the organism to infect the host for extended periods. Symptoms, when present, are non-specific and may initially lead to misdiagnosis, particularly if the patient has additional co-morbid conditions.
