Background:
Ascariasis, caused by the parasitic roundworm Ascaris lumbricoides, is one of the most common helminthic infections globally. Spread by contaminated soil through the fecal-oral route, A. lumbricoides typically infects the small intestine and has rarely been reported to infect the stomach.
Case Summary:
We describe an unusual case of a male in his 30s with a history of neuroendocrine tumor (NET) who immigrated from Colombia and who underwent esophagogastroduodenoscopy (EGD) and colonoscopy for further evaluation of abdominal pain. He was incidentally found to have a female Ascaris worm in his stomach that was retrieved during the EGD.
Conclusion:
Despite its rarity, gastric ascariasis can cause various non-specific yet distressing gastrointestinal symptoms in patients, and therefore should be considered in those with risk factors for helminthic infections.
