Most esophageal cancers are squamous cell carcinomas. We recently encountered a case of primary early adenoacanthoma occurring in the midesophagus. We herein report this case. The patient was a 59-year-old woman who visited the hospital with a chief complaint of dysphagia. Fluoroscopy of the esophagus revealed a serrated filling defect, 4.5 cm in long diameter, in the middle thoracic esophagus. By endoscopic biopsy, the diagnosis of adenoacanthoma of the esophagus was made. After preoperative irradiation with 30 Gy, subtotal resection of the thoracic esophagus was performed. Sections revealed a slightly irregular depressed lesion, 2.3×1.3 cm,8 cm aboral to the esophagogastric junction. Histopathologically, the tumor showed proliferation of squamous cell carcinoma cells centering around the ulcerated portion and in part of the adenomatous portion. The border between the two components was sharp. The depth of invasion was submucosal. Both types of lesions showed moderate degeneration due to preoperative irradiation. The efficacy of irradiation was evaluated as Ef2. This case was diagnosed as primary early esophageal adenoacanthoma, sm, n₀, M₀, Pl₀ and R-stage 0.
