Patient 1 was a female in her 50's and patient 2 was a male in his 80's. In both cases, submucosal invasion was suspected following conventional endoscopy. Using magnifying endoscopy and endoscopic ultrasonography, the depths of the tumors were diagnosed as T1a-EP and LPM with leiomyoma respectively. These 2 lesions were resected by endoscopic submucosal dissection in an en bloc fashion. Pathological examination of the 2 lesions showed squamous cell carcinoma, depth T1a-EP and LPM, with leimyoma, margin negative. It is essential to use 3 modalities correctly for precise diagnosis of superficial esophageal carcinoma.
