Giant Solitary Fibrous Tumor of Esophagus Resected by Endoscopic Submucosal Dissection.

Solitary fibrous tumor is one of the most common soft tissue benign tumors that occur in adults, but it rarely occurs in the gastrointestinal tract and even more infrequently occurs in the esophagus. Only 4 cases of esophageal solitary fibrous tumors have been reported in PubMed using the search terms "solitary fibrous tumor" and "esophagus". These cases were all treated using surgical methods. Thus, we report a case of primary solitary fibrous tumor of the esophagus treated by endoscopic submucosal dissection. Endoscopic submucosal dissection was well tolerated in this patient, suggesting that it may be a therapeutic option for primary giant esophageal neoplasms.
