Colorectal cancer can remain asymptomatic for years. Frequently symptoms develop insidiously and may often remain unnoticed for long periods, even in the presence of disseminated disease. We herein report an unusual case of a patient with carcinoma of the sigmoid colon and multiple liver metastases. The diagnosis was established only after the patient was operated on for a large colloid nodule, a single microscopic metastatic focus being noticed in the histologic sections. The differential diagnosis compared with the columnar type of papillary carcinoma is discussed.
结直肠癌可能多年无症状。症状通常隐匿出现，甚至在存在播散性疾病的情况下，也可能长期未被注意到。我们在此报告一例罕见病例，患者患有乙状结肠癌并伴有多处肝转移。该诊断仅在患者因一个大的胶体结节接受手术后才得以确立，在组织学切片中发现了单个微小转移灶。文中还讨论了与柱状乳头状癌的鉴别诊断。
