Popis:	We reported a case of asymptomatic extra-adrenal pheochromocytoma after perforating diverticulum of the sigmoid colon. A 63-year-old man was admitted to the hospital because of lower abdominal pain. Sigmoidectomy and atemporary colostomy were performed, and the post operative course was uneventful. Before the operation, and abdominal CT scan and ultrasonography showed incidentally an adrenal tumor with cystic component. But we left it alone at that time, because of emergency operation. Thereafter the tumor slightly enlarged in size. After close examination of radiological images and endocrinologic studies, the tumor was diagnosed as adrenal or extra-adrenal pheochromocytoma. The tumor was removed. The removed tumor was diagnosed as extra-adrenal pheochromocytoma histopathologically. No crisis occurred in the clinical course, but a high level of catecholamine was included in the cystic component. It is necessary to consider that the high level of catecholamine might be included in the cystic pheochromocytoma even in the asymptomatic case.
