食道癌は大部分が扁平上皮癌であるが,下部食道に発生した類基底細胞癌の1例を経験したので報告する.症例は62歳の男性でアルコール性肝硬変,食道静脈瘤で当院内科で内服治療中であった.上部消化管造影でEiに長径2cm, 隆起型の腫瘍を認め,内視鏡検査で下部食道に0-Iの隆起性病変を認めた.同部の生検では扁平上皮癌疑であった. 1996年2月27日,左開胸,開腹で手術を行った.下部食道,胃上部切除,脾摘除,食道胃吻合を行い, Ao, N(-), Mo, Ploで治癒切除であった.切除標本では大きさ, 2.2×1.5cm, 境界明瞭な表在隆起型腫瘍であった.病理組織所見では食道上皮の基底細胞類似の腫瘍細胞が充実性に配列して増殖しており,類基底細胞癌で深達度はsm,リンパ節転移を認めなかった.術後経過は良好で術後1カ月で退院し,術後8カ月の現在,健在である.

Most cancers of the esophagus are squamous cell carcinoma. We experienced a case of basaloid cell carcinoma of the intrathoracic esophagus.<br> A 62-year-old man, who had been treated for alcoholic cirrhosis and esophageal varices at the department of internal medicine in our hospital, was found out having an elevated tumor 2cm in longer diameter in Ei by barium meal study and esophagoscopy. With biopsy of the lesion, a squamous cell carcinoma of the esophagus was suspected. Under left thoracotomy and laparotomy, resection of the lower esophagus and upper portion of the stomach, splenectomy, and esophagogastrostomy were carried out. The tumor was Ao, N(-), Mo, and Plo, and the operation resulted in curative resection.<br> The resected tumor was 2.2×1.5cm in size, and well demarcated and protruded. Histologically, basaloid cell carcinoma was confirmed. The tumor infiltrated into the submucosal layer without lymph node metastasis.<br> Postoperative course was uneventful and the patient was discharged from the hospital one month after the operation. The patient is doing well eight months after the surgery.
