Urinary Bladder Pheochromocytoma with a Long Asymptomatic Period.: Soon Hong Park, Jung Eun Lee, Sung Soo Moon, Joo Young Lee, Eui Dal Jung, Jung Guk Kim, In Kyu Lee, Bo Wan Kim; J Korean Endocr Soc. 2006;21(5):402-407.

Abstract PDF: Pheochromocytoma arises from chromaffin cells of the paraganglionic system. Urinary bladder pheochromocytoma is very rare tumor that accounts for less than 0.06% of all urinary bladder tumors and it is less than 1% of all pheochromocytoma. Urinary bladder pheochromocytoma usually arises from the sympathetic nervous system of the bladder wall. Paroxysmal headache and palpitation precipitated by micturition are common specific symptoms of this tumor. The paroxysm commonly persists or the patients relapse in a few days or months. Herein, we report a case of urinary bladder pheochromocytoma with a long asymptomatic period.

A Case of Atypical Retroperitonealk Paraganglioma: Fatal paroxysmal adrenergic crisis and geart failure after sonographically guided biopsy of unsuspected paraganglioma.: Sung Koo Kang, Jong Min Lee, Sung Ro Yoon, Seok Young Kim, Jin Sung Moon, Hye Soo Kim, Young Jae Lee, Hye Kyung Bae, Hye Kyung Lee, Hyun Kim; J Korean Endocr Soc. 1998;13(2):280-287.

Abstract PDF: Paraganglioma is an extraadrenal pheochromocytoma originating from chromaffin ceIls distributed in sympathetic nervous systems. This tumor often can produce catecholamines and induce sustained or paroxysmal hypertension, with or without the typical symptams of headache, palpitation and sweating. Paraganglioma without the usual clinical manifestations is not easy to suspect and diagnose. Herein, we report a case of atypical retroperitoneal paraganglioma which was thought to be the pancreas tail mass and result in a paroxysmal adrenergic crisis and fatal dilated cardiomyopathy after the sonographically guided percutaneous biopsy. This rare case warns against the usual practice of percutaneous biopsy for the preoperative diagnosis of intraabdominal or retmperitoneal tumors.
