ePub - Strongyloides stercoralis is endemic to tropical and subtropical regions, and infections are usually asymptomatic. However, immunocompromised patients, such as those receiving immunosuppressive therapy, high-dose steroids, or chemotherapy, can develop fatal hyperinfections. An 84-year-old man without any symptoms was diagnosed with strongyloidiasis during a regular screening colonoscopy. His medical history only involved a gastric endoscopic submucosal dissection for early gastric cancer 6 months previously. Few cases have been published about asymptomatic strongyloidiasis diagnosed in an immunocompetent host via endoscopic mucosal resection with characteristic colonoscopic findings. We report a case of colon-involved asymptomatic strongyloidiasis with specific colonic findings of yellowish-white nodules. This finding may be an important marker of S. stercoralis infection, which could prevent hyperinfections.

Abstract
PDF
- Korea Strongyloidiasis is a parasitic disease caused by Strongyloides stercoralis which exists in two forms : the free living and parasitic forms. It exists in warm, moist climate in areas where there is frequent fecal contamination of the soil. After cutaneous invasion by the filariform larvae, petechial hemorrage, pruritus, papular rashes, edema, and urticaria occur. Infection commonly occurs in the proximal intestine of the gastrointestinal (G-I) tract but may extend from the stomach to the anus. Once the worm is established in the small intestine, the physical findings may include epigastric tenderness to palpation. The mucosal biopsy is an inefficient way of making the diagnosis because the worm is found in the biopsy specimen in only 2% of patients. Gastric strongyloidiasis is rare. We experienced a case of gastric strongyloidiasis diagnosed by the endoscopic biopsy and serologic test for parasite specific IgG antibody by micro-ELISA.
