title: Metastatic tumors of the umbilicus: report of two cases and review of the literature.
abstract: An umbilical nodule may be an early or late sign of metastatic spread from an internal malignancy. Usually it appears when the internal malignancy is widely disseminated and has been previously diagnosed. More rarely, such a nodule is the first sign of disease and eventually results in the diagnosis of the primary tumor. We present two cases which document examples of both events, in order to focus on the most relevant aspects of this condition.
