要旨　64歳，男性の逆流性食道炎を合併した食道乳頭腫の1例を経験したので報告した．食道造影と食道内視鏡検査では，胸部中部食道後壁に径2cmの表面顆粒上の隆起性病変がみられた．病変部はヨード染色で染色された．トルイジンブルー染色では逆流性食道炎のために部分的に染色された．病変部の生検では食道扁平上皮乳頭腫であった．病変部の完全生検のため，内視鏡的粘膜切除術（EMR）が内視鏡的粘膜切除用チューブ法（EEMR-tube法）により施行された．病変部は本法により完全にかつ安全に1回で切除された．組織学的診断は食道の扁平上皮乳頭腫であった．EMRは本例の診断と治療に対して非常に有用であった．

　We reported a case of squamous cell papilloma of the esophagus associated with reflux esophagitis in a 64-year-old man. Esophagography and esophageal endoscopic examination showed a granular surfaced elevated lesion 2 cm in diameter on the posterior wall of the middle intrathoracic esophagus. This lesion was stained by lugor, was also stained partially by toluidine blue because of its being associated with reflux esophagitis. This biopsy specimen showed squamous cell papilloma of the esophagus. Endoscopic mucosal resection (EMR) was performed for total biopsy using the endoscopic esophageal mucosal resection-tube method (EEMR-tube method). The lesion was resected in one piece completely and safely by this EEMR-tube method. Histological diagnosis was squamous cell papilloma of the esophagus. EMR was extremely effective for diagnosis and treatment in this case.
