We present a case of gastric and intestinal Crohn's disease associated with extra-intestinal manifestations of fever, rash in the lower limbs in a 12 years old boy. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) was performed for the diagnosis of the disease causing fever of unknown origin. Gastroscopy showed polypoid hyperplasia and ulcers in the stomach and their pathology suggested gastric Crohn's disease. Intestinal Crohn's disease was also diagnosed. Corticosteroids were temporarily effective. During 2 years of follow-up, there were clinical remissions and relapse confirmed by endoscopy in both the stomach and the small intestine.
Background ::: Differential therapy requires repeated diagnostic assessment for mapping and monitoring of disease activity in Crohn’s disease (CD).
Background ::: No residual disease (NRD) can be found in the specimen after endoscopic resection (ER) of biopsy-proven gastric neoplasm. This study aimed to evaluate the endoscopic and pathologic characteristics of patients with NRD and identify the cause and long-term prognosis.
