A CASE OF EARLY ESOPHAGEAL CARCINOMA DEVELOPING ON HEMANGIOMA

Abstract

An elevating lesion was detected in a 46-year old man in the esophagus by G. I. series. Endoscopy revealed a soft bluish plateau lesion on the right wall of esophagus at 28 to 32 cm from incisor, compatible with hemangioma. Furthermore, an early esophageal carcinoma of 0-Jib type unstained by iodine was found on the hemangioma. Esophageal carcinoma developing on hemangioma had never been reported. Treatment was first performed for hemangioma by endoscopic injection sclerotherapy, followed by endoscopic mucosal resection for carcinoma. The complete resection of neoplasms was possible avoiding bleeding.
