A 37-year-old male with chief complaints of vomiting, abdominal pain, and diarrhea presented to our hospital in June 2017. A blood test detected increased inflammatory response, and a computed tomography scan showed that wall thickening extended from the terminal ileum to the entire large intestine. Bacterial enteritis was suspected because his household members developed infectious enteritis; however, his symptoms did not improve after antibiotic treatment. High fever and peritoneal signs were observed on the 10th day of admission, and palpable purpura appeared on the lower extremities. The patient was administered methylprednisolone because Henoch-Schönlein purpura was also suspected. Subsequently, his symptoms improved, and the purpura disappeared.
