However, gastric involvement with the manifestation of upper gastrointestinal bleeding is an extremely rare condition due to Strongyloides stercoralis. Due to irregular excretion of larvae, unclear symptoms, paucity of effective diagnostic tools and low parasitic load, makes clinicians difficult to reach the diagnosis of strongyloidiasis. Here, we present a case of upper gastrointestinal bleeding due to a large gastric ulcer whose aetiology was identified to be Strongyloides stercoralis infection of the gastric region by the diagnosis of exclusion.en-USGastric ulcerGastrointestinal haemorrhageStrongyloides stercoralisStrongyloidiasisOther
