Infrequently, it may arise outside the usual distribution of the sympathetic and parasympathetic paraganglia. Tumors arising from the adrenal gland medulla are called pheochromocytomas. Morphologically, paragangliomas usually display a nesting (Zellballen) growth pattern. There are no reliable morphologic criteria to distinguish between benign and malignant paragangliomas. The only definitive indicator of malignancy is the presence of regional or distant metastases. neoplasm of paraganglion ICD9:239.7 paraganglion neoplasm UMLS:C0030421 DOID:0050773 paraganglioma MEDGEN:10571 SCTID:127027008 paragangliomas tumor of paraganglion ICDO:8680/1 neoplasm of the paraganglion ONCOTREE:PGNG EFO:1000453 tumour of the paraganglion Paraganglionic tumour tumour of paraganglion Paraganglionic neoplasm MESH:D010235 Paraganglionic tumor chemodectoma autonomic nervous system neoplasm neuroendocrine neoplasm neurocristopathy hereditary neurological disease autonomic nervous system
