Abstract:
Many pheochromocytoma and extra-adrenal paraganglioma are benign, but some are malignant. Pheochromocytoma of the Adrenal gland Scaled Score analyzed the histological characteristics of the tumor. Tumors with a Pheochromocytoma of the Adrenal gland Scaled Score of 4 or higher have a higher risk of recurrence. This pattern is thought to be applicable to paraganglioma as well, and to future patient follow-up efforts. We report a recurrent and metastatic paraganglioma of the urinary bladder.
