background: intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. in this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. methods: the present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...
Recently, long non-coding RNAs (lncRNAs) have received increased research interest owing to their participation via distinct mechanisms in the biological processes of nonfunctional pituitary adenomas. However, changes in the expression of lncRNAs in gonadotrophin adenoma, which is the most common nonfunctional pituitary adenomas, have not yet been reported. In this study, we performed a genome-...
Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...
Pituitary adenomas usually arise from the anterior lobe of the pituitary gland and are manifested with hormonal disorders or mass effect. Mass effect usually occurs in nonfunctional tumors. Pituitary adenomas may be manifested with visual field defects or rarely in the form of total oculomotor palsy. Visual field defect is most frequently in the form of bitemporal hemianopsia and superior tempo...
background: nowadays, drug and observation are advised to patients with lymphocytic hypophysitis and in some cases with nonfunctioning pituitary macoadenoma, instead of surgery. case presentation: in this article, we report a woman with nonfunctional pituitary macroadenoma and panhypopitutarism and negative criteria for lymphocytic hypophysitis associated with increased liver enzymes. after thr...
We sought to investigate the expression of EpCAM and Trop2 in Pituitary adenomas (PAs) and study the correlation of protein expression with invasiveness, proliferation, clinical functioning, recurrence/progression, and some other factors. We investigated the expression of EpCAM and Trop2 in 74 samples of PAs by immunohistochemistry and made correlative analysis of protein overexpression with cl...
