子宮癌との異時性重複を示し長軸方向への進展が著明であった上行結腸癌の1例

Adenocarcinoma of the Ascending Colon Showing Longitudinal Growth and Associated with Metachronous Endometrial Carcinoma, Report of a Case

　上行結腸に発生した癌が，主として腸管の長軸方向に進展し，一部はBauhin弁を越えて回腸に浸潤した症例を報告する．患者は結腸癌手術後2年目に子宮癌を併発し，しかも兄が大腸癌（多発）と胃癌（多発）に罹患，妹が胃癌で死亡するなど癌多発の家系としても注目される．

　A case of adenocarcinoma of the ascending colon showing an unusual growth pattern in a 50-year-old woman is presented. The tumor grew longitudinally extending from the terminal ileum to the proximal two-thirds of the ascending colon, measuring 15 cm in length and 6 cm in width. In spite of its large size, the tumor was confined within the wall. Two years postoperatively, the patient also developed another primary endometrial carcinoma. Another point of interest in this case is the family history showing clustering of gastrointestinal cancer in her brothers and sisters. Among five of the members including the present patient, three developed carcinoma of the gastrointestinal tract; her elder brother had multiple gastric carcinomas and metachronous multiple colonic carcinomas, and her sister died of carcinoma of the stomach.
