Kyung Seop Lee, Jung Dam Kim, Ki Ho Kim, Young Jin Seo, Jong Im Lee, Young Sil Lee, Sung Woo Kim From the Departments of Urology, Pathology, Internal Medicine, Radiology, College of Medicine, Dongguk University, Gyeongju, Korea Paragangliomas of the urinary bladder are very rare tumors of the paraganglion system that arise from chromaffin cells in or near the sympathetic ganglia. Only approximately 15% of them develop from extra-adrenal chromaffin tissue. Most of these tumors are hormonally active and secrete mainly noradrenaline (rarely adrenaline), calcitonin, and adrenocorticotropic hormone. Paragangliomas are generally benign tumors, with less than 10% being malignant. Here we report a case of a paraganglioma arising in a urinary bladder with a bladder stone.
