Abstract

Gastric subepithelial tumor is a common finding of upper gastric endoscopy. Differential diagnosis is needed, sometimes a rare disease can be found. Calcifying fibrous tumor is a rare benign fibrous tumor, and mostly affects children and young adults. It can involve all over the body, and shows predilection for abdominal cavity and peritoneum. Stomach lesions are quite rare. We report a case of a 43-year-old woman with a calcifying fibrous tumor presenting as gastric subepithelial tumor. Initially, a subepithelial lesion measuring 8 cm in diameter was incidentally found on her gastric endoscopy, and she had no symptoms. Computed tomography showed an exophytic mass originating from the gastric wall. Laparoscopic wedge resection was performed on the suspicion of gastrointestinal stromal tumor. Pathologically, the tumor showed hypocellular and densely hyaline collagen. Psammomatous calcifications and fibroblastic spindle cells were also found. On the basis of pathological findings, calcifying fibrous tumor was diagnosed.
