Abstract
Strongyloidiasis is a common parasitic disease in tropical regions of the world. Infection withStrongyloides stercoralisusually remains asymptomatic with peripheral eosinophilia and uncontrolled growth. Consequently, immunocompromised individuals are at a higher risk of complications of this disease. We present a case of an immunocompetent patient whose complaint of acute abdominal pain was found to be due to gastric and duodenal ulcerations. Laboratory examination revealed significantly elevated absolute eosinophil count at 11,466/mm3(normal 0–700/mm3). The duodenal biopsy revealed parasitic ova and adult worms suggestive ofStrongyloides stercoralisnematode with increased eosinophils in the tissue. We report the first case of multiple gastric and duodenal ulcerations due toStrongyloides stercoralisin an immunocompetent patient. We suggest that the elevated eosinophil count played a central role in the pathogenesis.
