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.

伴有局部复发和盆腔转移的侵袭性膀胱副神经节瘤

许多嗜铬细胞瘤和肾上腺外副神经节瘤是良性的，但也有一些是恶性的。肾上腺嗜铬细胞瘤分级评分分析了肿瘤的组织学特征。肾上腺嗜铬细胞瘤分级评分为 4 或更高的肿瘤复发风险较高。这种模式被认为也适用于副神经节瘤，以及未来的患者随访工作。我们报告了复发性和转移性膀胱副神经节瘤。
