Popis: We present the case of an adolescent who presented with rhabdomyolysis due to severe hypokalemia arising from chronic diarrhea. Initial evaluation for celiac disease, known to present in this manner, was negative. Further evaluation with colonoscopy showed a normal appearing colon but biopsies showed a significant number of apoptotic cells in the mucosal crypts supporting a diagnosis of apoptotic colitis. Investigation into the cause of apoptotic colitis resulted in a diagnosis of common variable immune deficiency due to a defect in the inducible T-cell costimulator (ICOS) gene. Physicians should be aware of this uncommon condition and the importance of mucosal biopsy despite the presence of normal appearing mucosa.
