https://www.selleckchem.com/products/pt2399.html The optic nerve is an unusual site of schwannoma as it lacks Schwannoma cells on it. We report a primary optic sheath schwannoma and to review the literature. A 29-year old female presented with progressive painless non-pulsatile proptosis. Ocular examination revealed only axial proptosis. Imaging showed a well-defined intraconal mass abutting optic nerve. A left frontal craniotomy with orbitotomy and tumor excision was done. The tumor was well encapsulated, posteriorly attached to optic nerve without any plane, probable site of origin. The postoperative duration was uneventful without any complications. The histopathology examination confirms the diagnosis of schwannoma. We suggest to consider orbital optic nerve schwannoma in differential diagnosis of orbital tumors despite its exceedingly rare occurrence.

The purpose of the present study was to analyze the impact of the neutrophil-lymphocyte ratio (NLR) on the long-term outcomes of patients with adrenocortical carcinoma (ACC). This retrospective, single-institution study included 48 patients with the diagnosis of ACC. The primary outcomes of the study were differences in overall survival (OS) and disease-specific survival (DSS) with respect to the NLR level. Patients with ENSAT stage IV had higher levels of NLR compared to those with ENSAT stage I-III (5.7 (1.6-12.5) vs 3.3 (1.3-11); =.01). A higher NLR was also observed among patients with cortisol-secreting tumors (4.6 (1.7-12.5) vs 2.8 (1.3-10.3); =.003) and those with Ki-67 index >10% (4.3 (1.3-12.5) vs 2.6 (1.6-11.0); =.005). With respect to survival, the univariate analysis revealed worse ACC-related survival ( =.02) and OS ( =.004) in patients with NLR >3.9 than in those with NLR ≤3.9. In addition, patients with NLR >3.9 had a higher Weiss score ( =.046), a higher Ki-67 i
