Strongyloidiasis in a Patient with Colonic Pseudopolyps and Intermittent Eosinophilia

Strongyloides stercoralis is a parasitic infection which is endemic to the subtropics but uncommon in the northeastern United States. Strongyloides is unique in that it can remain latent in asymptomatic carriers for years. The gastrointestinal findings of Strongyloides infection can vary and are not well studied. In some cases, Strongyloides can present with polyp formation and colonic ulceration leading clinicians to suspect malignancy or Inflammatory Bowel Disease. However, corticosteroid administration is contraindicated due to risk of disseminated Stronglyoides infection which has a reported mortality as high as 68%. In this case report we discuss the gastrointestinal and pathology findings of a 71 year old patient with non-disseminated gastrointestinal Strongyloides infection.
