A patient with eosinophilia, hypoalbuminemia and abdominal pain.

Strongyloides stercoralis infections frequently present with eosinophilia and abdominal pain. Since the gastrointestinal symptoms are non-specific, only 15 percent of these patients are correctly considered to have an infectious enteritis or intestinal parasite. In fact, the initial diagnosis is peptic ulcer disease in most patients. The clinical course may be indolent, or patients may develop a sudden catastrophic illness, particularly following the administration of corticosteroids.
