胃カルチノイドの1例

A Case of Gastric Carcinoid.

　今回，私どもは胃X線，内視鏡検査上興味ある所見を示した胃カルチノイドの1例を経験したので，そのX線，内視鏡所見を中心に報告する．

　患　者：加○　昇　52歳　男性

　主　訴：なし（人間ドック）

　既往歴・家族歴：特になし．

　経　過：昭和46年8月人間ドックで胃に異常所見なし，昭和48年3月再度の人間ドックで胃X線検査で異常所見を指摘され，胃内視鏡，生検の結果，胃癌と診断され昭和48年5月胃切除術をうける．

　Abnormal finding in the stomach was pointed out to a 52-year old male patient in the course of human dock examination. He has had no carcinoid symptoms, though urine 5-HIAA and serum serotonin was not checked. The presext paper deals with the radiographic, endoscopic and exoloratory findings of this case.

　Radiographically we found three protruded lesions, hard to determine whether of epithelial or nonepithelial natnre. On the surface of the lesions and among them, there existed irregular depressions and the radiographical diagnosis was gastric sarcoma or Ⅱc+Ⅱa type. Endoscopy showed findings of multiple submucosal tumors.

　The resected specimen showed that there were at the lower gastric corpus an irregularly depressed portion and three submucosal tumors around it. Histological diagnosis was carcinoid confirmed as such after argyrophil staining and electron-microscopy.

　Cut specimen showed that tumor remained mainly in the deep Iayer of the mucosa and the location of this tumor was exactly reflected in our x-ray finding. We might call this finding as that of “epithelial submucosal tumor”.
