A 22-year-old man presented to clinic with a 1 year history of bloody diarrhoea and weight loss. Flexible sigmoidoscopy showed the presence of a low polypoidal rectal carcinoma. Whilst awaiting neoadjuvant chemo-radiotherapy, the patient presented to accident and emergency with an anal protrusion of the tumour. An emergency laparotomy unexpectedly revealed a mid sigmoid tumour which had intussuscepted through the anus and therefore required an anterior resection as opposed to an abdomino-perineal resection. Colorectal carcinoma presents in a specifically unique pattern in patients less than 30 years. We present this rare case with a brief review of the literature.
一名22岁男性因便血和体重减轻1年就诊于门诊。乙状结肠镜检查显示存在低位息肉样直肠癌。在等待新辅助放化疗期间，患者因肿瘤经肛门突出而急诊入院。急诊剖腹探查意外发现乙状结肠中段肿瘤经肛门套叠，因此需要行前切除术而非腹会阴联合切除术。30岁以下患者的结直肠癌表现出一种特殊的独特模式。我们报告这一罕见病例并对文献进行简要回顾。
