Calcifying fibrous tumor originating from the gastrohepatic ligament that mimicked a gastric submucosal tumor: A case report

BACKGROUND: Calcifying fibrous tumor (CFT) is a rare, benign soft tissue tumor usually occurring in children or young adults. Gastrohepatic ligament CFT with adhesion to the stomach is very rare. We present a case here. CASE SUMMARY: A 25-year-old woman visited our hospital with abdominal pain. Computed tomography and endoscopy were performed, and a gastric submucosal tumor (SMT) with a size of 6.7 cm × 2.7 cm was detected, so endoscopic ultrasonography-guided fine needle biopsy was performed. The tumor was not diagnosed histologically, so surgical resection was planned and performed. The histopathologically confirmed mass size was 6.5 cm × 4.0 cm × 1.0 cm, and a calcified fibrous tumor that originated at the gastrohepatic ligament and adhered to the lesser curvature of the gastric antrum was identified. CONCLUSION: Gastrohepatic ligament CFT is a very rare benign tumor. Since this disease may be confused with gastric SMT, the possibility of CFT should be kept in mind during clinical assessment of this disease.
