BACKGROUND Gastrointestinal schwannomas(GIS)are rare neurogenic tumors arising from Schwann cells in the gastrointestinal tract.Studies on GIS are limited to small case reports or focus on specific tumor sites,undersc...
BACKGROUND Schwannoma is a benign,encapsulated and slowly growing tumor originating from Schwann cells and is rarely seen in the peripheral nerve system.Typical symptoms are soreness,radiating pain and sensory loss co...
BACKGROUND Gastrointestinal schwannomas are slow-growing benign mesenchymal neoplasms that originate from Schwann cells of the nerve sheath of Auerbach′s plexus or less frequently from Meissner′s plexus.The main dif...
Background: Spinal schwannomas are common tumors of spinal neoplasm and account for about 25% of intradural spinal cord tumors in adults. They are generally benign and slow-growing. Advanced in radiologic and surgical...
Intratemporal facial nerve schwannoma(FNS) are rare benign tumors of the skull base. Many of these tumors will be detected during evaluation for symptoms suggestive of vestibular schwannoma. However, there are several...
Introduction: Schwannomas (SNs) are rare tumors derived from Schwann cells. They can occur almost anywhere, but the most common location is cranial nerve VIII where they present as acoustic neuromas. SNs rarely may be...
Schwannomas are usually benign tumors that arise from a nerve supporting the Schwann cells, those are mostly associated with the cranial or main peripheral nerves. The occurrence of retroperitoneal schwannoma is quit...
AIM: To investigate the role of angiopoietin (Ang) -1, -2 and -4 and its receptors, Tie-1 and -2, in the growth and differentiation of gastrointestinal stromal tumors (GISTs).METHODS: Thirty GISTs, seventeen leiomyoma...
AIM: To investigate the role of vascular endothelial growth factor (VEGF/and its receptors VEGFR-1 and 2 in the growth and differentiation of gastrointestinal strornal tumors (GISTs). METHODS: Thirty-three GISTs,...
Background Schwannoma is the tumor arising mainly from the cranial and spinal nerves. Bilateral vestibular schwannoma is the hallmark of neurofibromatosis type 2 (NF2). The NF2 gene has been cloned with comprehensiv...
