RationaleCalcifying fibrous tumor (CFT) is a rare benign soft tissue mesenchymal neoplasm. Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma.Patient ConcernsA 55-year-old man presented with complaints of epigastric discomfort and abdominal distention for more than 1 year.DiagnosesOn the basis of endoscopic and computed tomography examination, preliminary diagnosis was GIST.InterventionsEndoscopic submucosal dissection (ESD) surgery was performed to remove the gastric mass.OutcomesThe histopathological examination revealed a gastric CFT.LessonsWe present a case of gastric CFT, which was misdiagnosed as GIST based on endoscopic and radiologic findings.Copyright © 2017 The Authors.
