 The patient was a male in his fifties. Conventional esophagoscopy revealed a red flat lesion, about 7cm in size located at the middle thoracic esophagus with a whitish elevated tumor. The protruded lesion arose gently and had a granular/nodular surface pattern covered with normal mucosa. NBI magnified endoscopy revealed irregular-branched and slightly dilated non-loop vessels which have a poor caliber change in vessels. EUS(IDUS, 20MHz)showed a hypo echoic mass lesion invading to the SM2~3. Because of the submucosal tumor-like protruded lesion with the granular/nodular surface pattern showing a vascular pattern similar to type 4R largely covered with non-neoplastic epithelium, the tumor was diagnosed as non-squamous cell carcinoma, especially basaloid squamous carcinoma or adenosquamous carcinoma. Video-Assisted Thoracic Surgery for the Esophagus with three-field lymph node dissection was performed. Histologically, the tumor was diagnosed as basaloid squamous carcinoma(pSM2)with squamous cell carcinoma(pEP/LPM), INFb, ly0, v0, pPM0, pDM0, pRM0, SMT-like, 27×20mm, N0.
