A 13-year-old boy who had epigastric pain and pallor for 2 months and found to have an ulcerative mass in the stomach and underwent partial gastrectomy. A diagnosis of inflammatory myofibroblastic tumour (IMT) of the stomach was made on histological examination. Three years later, recurrence in the stomach, with invasion into the pancreas and hilum of the spleen was noted and was managed by wide wedge resection of the stomach, distal pancreatectomy and splenectomy. The patient has been recurrence-free for the past 2 years. Gastric IMT is an uncommon tumour in children with unpredictable prognosis.
