本瘤罕见,副节瘤依其主细胞对铬盐的反应,有嗜铬性与非嗜铬性之分,但两者并非截然不同的特征,可能只是程度上的差异。嗜铬性副节发生的肿瘤,习称嗜铬细胞瘤,源自非嗜铬性副节者常简称副节瘤,实际上两者均属副节瘤,分别冠以“嗜铬性”与“非嗜铬性”,则更合乎命名原则。此外,将所有非嗜铬性副节瘤统称化感瘤欠确切。副节瘤属APUD瘤范畴,与类癌渊源较近。 This tumor is rare. The accessory nodules respond to chromium salts in their host cells. They are divided into chromaffin and non-chromium, but these two are not distinct features and may differ only in degree. The tumors that occur in the paragangliotropia of the pheochromocytosis are often referred to as pheochromocytomas. They are often referred to as parabranch tumors in non-chromostatic paragangliomas. Actually, both are parabranch tumors, and are respectively labeled as “chromophilic” and “Non-chromatogenicity” is more consistent with the naming principle. In addition, it is not clear that all non-Chromosomal paraganglioma tumors are collectively called tumors. The paraganglioma APUD tumor category, and carcinoid sources.
