Solitary Metastatic Carcinoma of Colon from Renal Cell Carcinoma Misdiagnosed as Primary Colon Carcinoma

The gastrointestinal tract, particularly the colon, represents a rare site of metastatic carcinoma. It is difficult to diagnose because of its nonspecific clinical and imaging features. Herein, we reported the case of a 64-year-old Asian male who presented with a solitary mass on his right colon. We...

Description
Summary:The gastrointestinal tract, particularly the colon, represents a rare site of metastatic carcinoma. It is difficult to diagnose because of its nonspecific clinical and imaging features. Herein, we reported the case of a 64-year-old Asian male who presented with a solitary mass on his right colon. We successively performed contrast-enhanced ultrasonography, computed tomography (CT) and colonoscopy. Colonoscopy-guided biopsy revealed inflammatory granulomatous and necrotic tissue. The mass was resected and identified as a metastatic carcinoma of renal cell carcinoma (RCC). The details of the case and review of related articles are presented.
