Craniopharyngioma: Survivin expression and ultrastructure
The aim of the present study was to investigate the significance of survivin protein expression levels in craniopharyngioma. Tumor samples and clinical data were obtained from 50 patients with craniopharyngioma who were admitted to the West China Hospital of Sichuan University (Chengdu, China). The morphology of the craniopharyngioma samples was observed using optical and electron microscopes, ...

Craniopharyngiomas are benign slow growing tumours that are located within the sellar and para sellar region of the central nervous system. The point prevalence of this tumour is approximately 2/100,000.

متن کامل[Craniopharyngioma--a "geographical malignant" tumour].
The craniopharyngioma is a rare dysontogenetic tumour that originates from either scattered cells of the craniopharyngeal duct or from metaplastically mutated anterior pituitary parenchyma cells. Despite being classified as a WHO-Class-I tumour, the histologically benign craniopharyngioma may display an aggressive behaviour. Like other congenital tumours, it usually becomes manifest within the ...
متن کاملMetastatic craniopharyngioma.
We report a unique case of metastatic craniopharyngioma. Initially, the patient had a right frontal craniotomy for resection of a suprasellar mass, which was determined to be an adamantinomatous craniopharyngioma. Seven years later, an MR study of the brain showed two peripheral enhancing lesions adjacent to the dura and contralateral to the craniotomy site. Pathologic examination again showed ...
متن کاملCraniopharyngioma: A Case Report of Ectopic Recurrence.
Ectopic recurrence of craniopharyngioma is extremely rare. Two mechanisms have been proposed to explain this phenomenon: direct implantation along the previous surgical tract and dissemination via cerebrospinal fluid (CSF). We present a case of ectopic recurrence along the surgical route after transcranial gross total resection (GTR) of primary tumor. Cystic tumor seems to be a risk factor of e...
