Calcifying fibrous tumor of stomach

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. PatientconcernsA 55-year-old man presented with complaints of epigastric discomfort and abdominal distention for more than 1 year. Diagnoses On the basis of endoscopic and computed tomography examination, preliminary diagnosis was GIST. Interventions Endoscopic submucosal dissection (ESD) surgery was performed to remove the gastric mass. Outcomes The histopathological examination revealed a gastric CFT. Lessons We present a case of gastric CFT, which was misdiagnosed as GIST based on endoscopic and radiologic findings. Abbreviations: CFT = calcifying fibrous tumor, CT = computed tomography, ESD = endoscopic submucosal dissection, GI = gastrointestinal, GIST = gastrointestinal stromal tumor.
