Gastrointestinal stromal tumours (GISTs) are very rare gastrointestinal (GI) mesenchymal tumours affecting only 0.02 children/million/year below the age of 14 years. We reported a 9-year-old girl presented to emergency department with pallor and haemoglobin of 50 g/L. Extensive workup for anaemia suggested iron-deficiency anaemia secondary to GI loss. Ultimately after blood transfusion of packed cells, she was discharged with a haemoglobin of 92 g/L with iron supplementation. Upper endoscopy showed incidental antral nodularity with biopsy proven helicobacter gastritis and an isolate 3–4 cm suspicious mass in the lesser curvature. Abdomen imaging confirmed the gastric mass in addition to two lesions, one retroperitoneal and one paraspinal. She undergone open laparotomy with complete surgical resection of the gastric and retroperitoneal masses with histological confirmation of GIST and paraganglioma. This case emphasises the importance of proper examination of the stomach at endoscopy and to illustrate that although anaemia is common in paediatric age group it may be reflect serious medical condition even in normal looking child.
