Abstract
A 60-year-old man developed vomiting and abdominal pain 30 min after eating sulfur tuft mushrooms (Hypholoma fasciculare) and was brought to our hospital. The symptoms resolved on hospital day 2, but he again developed vomiting and abdominal pain together with tarry stools on hospital day 3. Upper gastrointestinal endoscopy on hospital day 4 showed continuous and circumferential redness, edema, erosions, and hemorrhage from the superior duodenal angle to the descending part of the duodenum. The symptoms resolved over time with conservative treatment. Endoscopy on hospital day 9 showed no evidence of hemorrhage, but a granular mucosa and linear ulcers were found in the descending part of the duodenum. The patient was discharged from the hospital on hospital day 14 after his symptoms had resolved. Endoscopy after hospital discharge showed only linear scars. There are few reports of gastrointestinal lesions produced by mushroom poisoning. Therefore, we believe that our case, in which the gastrointestinal changes were also followed up endoscopically, is noteworthy.
