Two unusual presentations of carcinoma of the right colon are described. One of the two patients presented with a right gluteal abscess and the other presented with a colocutaneous fistula to the anterior abdominal wall at the site of a previous appendectomy scar. Despite extensive local tumor invasion of adjacent structures in both cases, all the regional lymph nodes were free of cancer and the tumors were of low-grade malignancy. A review of the literature indicates that bulky colonic tumors with extensive local invasion and negative mesenteric lymph nodes have a relatively good prognosis if adequate resection is performed.
本文描述了右半结肠癌的两种不寻常表现。两名患者中的一名表现为右臀部脓肿，另一名则在既往阑尾切除疤痕处出现与前腹壁相通的结肠皮肤瘘。尽管在这两个病例中肿瘤均广泛侵犯了邻近结构，但所有区域淋巴结均无癌细胞转移，且肿瘤为低级别恶性。文献回顾表明，如果进行充分切除，具有广泛局部侵犯且肠系膜淋巴结阴性的巨大结肠肿瘤预后相对较好。
