 We reported our experience with one patient of CFT(calcifying fibrous pseudotumor)which occurred in the esophagus. The case was a 61-year-old women. We consulted a specialist about her chief complaint which was a feeling of some sort of blockage in the esophagus after editing a submucosal tumor lesion in the lower esophagus, was found. X-ray examination and endoscopy showed no abnormality in the mucosal surface. However, a mass with clear boundaries with calcification was shown by CT. We undertook lower esophagus resection because of the diagnosis of a denatured leiomyoma. The comparatively firm submucosal mass,5.8cm in size, was present in the esophageal lumen, and a white enhancement with clear boundaries in the sectioned surface-related mass showed a lot of calcification. The cell density was poor, and the fusiform cells were not of the aberrant type and, histologically, were shown to be scattered a resected specimen showed hyalinization and calcification including psammoma body, and there was mild lymphocytic and plasma cell infiltration into the mass. Immunohistologically tumor was CD34 negative,α-smooth muscle actin negative,S-100 negative, c-kit negative, vimentin positive.

 We presented a case of CFT of the esophagus. To our knowledge, this is the first case to be described.
