Abstract
Metastatic lesions of the colon are a rare clinical entity that may present difficulties in management. The incidence of these metastases appears to be increasing, as a result of physicians' greater awareness during follow-up investigations of a primary neoplasm. Furthermore, the presence of a greater proportion of these abnormalities at autopsy should be a triggering factor for further investigation for doctors dealing with colorectal oncology. Their clinical presentation may vary from asymptomatic to signs similar to those of colorectal cancer. However, immunohistological analysis is considered the cornerstone for differentiating metastases to the colon, originating from other primaries, from primary colorectal neoplasms. Survival reports and treatment options vary. This article concisely presents the main characteristics of the secondary lesions to the colon from neoplasms that metastasize to the large intestine (namely, lung, ovary, breast, prostate, kidney, and melanoma) focusing on their incidence, their clinical presentation and the workup investigation. Physicians aware of this uncommon entity are much better prepared to apply an efficient diagnosis and workup, as well as an appropriate treatment strategy.
