Pheochromocytoma are rare neuroectodermal tumors, responsible for less than 1 per cent of cases of hypertension. The protean manifestations of pheochromocytomas arise from the effects of catecholamine hypersecretion upon α and β receptors. The lesion may infrequently present with gastrointestinal complaints ranging from constipation and nausea to megacolon and ischemic colitis, ischemic colitis in association with pheochromocytoma occurs from intense splanchnic vasoconstriction. A case of pheochromocytoma presenting as ischemic colitis is reported.
