Core Tip

Core Tip: The right-sided sigmoid colon was first described by a few cadaveric studies and may not have been fully recognized by clinicians in recent years due to its relative rarity. Recognizing this variation is essential for interventional and diagnostic colonoscopy and associated surgeries. This is the first clinical case of a carcinoma located in a right-sided sigmoid colon.
