Calcifying fibrous tumour (CFT) is an uncommon benign fibrous neoplastic lesion that may manifest as singular or multiple tumours and usually occurs in children or young adults. CFT originates in the muscularis propria of the stomach and is a very rare disease. Here, we report a case of gastric CFT with upper gastrointestinal bleeding.A 39-year-old male was urgently referred to our hospital with haematemesis and melena that had developed over the course of 2 hours. Enhanced abdominal CT imaging revealed a nodular lesion, measuring approximately 3.2 × 2.1 × 1.6 cm, protruding from the posterior wall of the gastric body into the gastric lumen. The lesion exhibited scattered calcifications, smooth margins, and a CT attenuation value of 50 Hounsfield units (HU). Gastroscopic ultrasonography performed in the gastroenterology department revealed a semicircular submucosal mass with signs of active bleeding. Initially, the tumour was diagnosed as a gastrointestinal stromal tumour (GIST), and surgical intervention was undertaken due to ongoing haemorrhage. Postoperative histopathological examination confirmed the diagnosis of a gastric calcifying fibrous tumour (CFT).CFT originating from the muscularis propria of the stomach is exceptionally rare, and the case presented here mimicked a gastric submucosal tumour (SMTs),clinicians should consider this differentia diagnosis when evaluating patients with suspected cases.
