The coexistence of esophageal submucosal tumors and carcinomas is rare and the association between them is still unclear. Here, we report a case of a superficial esophageal carcinoma that developed over an esophageal leiomyoma, which was removed successfully by an endoscopic mucosal resection. A 76-year-old man was admitted for the treatment of an esophageal carcinoma. The endoscopic examination revealed a 1 cm-sized round, flat, elevated lesion located at the 25 cm mark of the endoscopy. Endoscopic ultrasonography revealed the carcinoma to be limited to the mucosal layer. Interestingly, a 1.2 cm sized, hypoechoic, subepithelial mass was present beneath the carcinoma. An endoscopic resection was performed simultaneously using a suction and snaring method with a transparent cap attached to the tip of the endoscope. A histopathology examination revealed a squamous cell carcinoma restricted to the mucosa immediately over the benign leiomyoma arising from the muscularis mucosa. The patient has remained well during 1 year follow-up period and has shown no evidence of recurrence.
