A patient with Charcot-Marie-Tooth disease developed profuse mucinous diarrhea and severe potassium depletion. After two weeks, her muscle weakness grew worse, rhabdomyolysis occurred, and kaliopenic nephropathy was suspected. The patient's diarrhea ended abruptly after a single tubular adenomatous polyp was removed from her colon. Her metabolic status became normal and remained normal six weeks after transcolonic polypectomy.
