Schwannoma of the Upper Limb: Retrospective Study of a Rare Tumor with Uncommon Locations.

Background: Although schwannoma (neurilemmoma) is the most common tumor of the peripheral nerve, its low incidence, slow growth and vague symptoms often lead to misdiagnosis or delayed diagnosis. The aim of the study is to present a series with a large number of schwannomas in the upper limbs, some with very rare occurrence.

Methods: We report 17 patients with a mean age of 58.

PD-L1 Expression in Esophageal and Gastroesophageal Junction Carcinoma, Correlation with the Immune Infiltrate - Preliminary Study.

Although traditional management for esophageal and esogastric cancer has been improved, survival at 5 years is still low, and immunotherapy could be a way to improve it. In addition to the predictive value of the response to immunotherapy, PD-L1 also has a known prognostic value. We aimed to evaluate the immunohistochemical expression of PD-L1, CD8+ T-cell, and CD4/CD25+ T-cell (Tregs) infiltration and their relationship in esophageal and gastroesophageal junction carcinoma.

Ivor Lewis Minimally Invasive Esophagectomy - What Do We Choose? Literature Review.

The transition from open esophagectomy to Ivor Lewis to minimally invasive surgery has been gradual through hybrid approaches. The aim of this study was to present a comparison of the current variants of minimally invasive Ivor Lewis esophagectomy. A systematic literature search was performed to analyze the technical features of minimally invasive Ivor Lewis esophagectomy and their postoperative results.

Clinical, histopathological and immunohistochemical features of glomus tumor of the nail bed.

Purpose: Glomus tumors account for 1-4% of benign hand tumors. In 65% of cases, it is located in the nail bed. Its rarity makes misdiagnosis problems relatively common.

Idiopathic tenosynovitis with rice bodies.
