Core Tip

Core tip: Protein-losing enteropathy (PLE) is characterized by loss of serum proteins into the gastrointestinal tract. The small intestine is the most common site of protein loss. This is an unusual case of severe PLE involving the sigmoid colon and the rectum. Surgical resection was performed and subsequent histologic evaluation confirmed a diagnosis of a pseudomembranous colitis with cap polyposis-like features.
