ABSTRACT
Objective:To investigate the clinicopathologic features of intraspinal ganglioneuroma.Meth-ods:We collected 1 2 cases of diagnosed ganlioneuroma arising from the spine and one case of ganlioneuro-ma arising from mediastinum as the control.Clinical and radiographic features were reviewed.The pathologi-cal parameters of these cases were analyzed with routine and immunohistochemical stainings of neural fiber (NF),S-100 protein(S-100),myelin based protein(MBP),peripheral myelin protein 22(PMP22),smooth mus-cle actin(SMA),glial fibrilary acidic protein(GFAP)and Ki-67.Results:The disease was likely to occur in pa-tients aged 30-40 years old and more common in female.These cases were all intral cervical spinal tumors and presented with radicular neuralgia and mass effects of cervical spinal cord compression.Ganglioneuro-mas which occasionally contained normal spindle shaped cells were composed of mature or degenarative ganglion cells and neoplastic Schwannian stroma.Ganglion cells appeared positive for NF.Schwannian stro-ma as well as satellite cells around ganglion showed immunoreactivity for S-100.more intense than neurofi-bro-stroma.Mature spindle shaped cells showed immumoreactivity for MBP.Ki-67 labeling indices were usual-ly 0-1%while in Schwannian stroma areas were 3%.No blood vessel endothelium proliferation was ob-served.Conclusion:Intraspinal ganglioneuromas are rare benign tumors(WHO grand I),causing radicular neuralgia.It is jmportant to distinguish ganglioneuroma with spinal root encircled from Schwannoma or neuro-fibroma in the same anatomic location.The optimal treatment is surgical total resection.
