Extra- and intraneural ganglion cysts have been described in the literature. The tibial nerve ganglion is uncommon and its occurrence without intra-articular extension atypical. The pathogenesis of cystic degeneration localized to connective and perineural tissue secondary to chronic mechanical irritation or idiopathic mucoid degeneration is hypothesized. Since the above pathology is extremely rare and the magnetic resonance imaging examination detects the defining characteristics of the intrinsic alterations of the tibial nerve, the authors illustrate such a case of tibial intaneural ganglion cyst with its magnetic resonance neurography and sonography appearances...

Periorbital nerve enlargement commonly indicates perineural invasion of malignancy or inflammatory conditions. This study reviews the role of supraorbital and infraorbital nerve biopsies in patients presenting with radiographic enlargement and to elucidate the surgical technique involved. A retrospective chart review (1997-2014) was performed at a single tertiary center. Patients with radiographic confirmation of enlarged supraorbital/infraorbital nerves that underwent biopsy were included. Charts were reviewed for: patient demographics and history, clinical symptoms and findings, radiographic findings, surgical method, and treatment...

Nonspecific orbital inflammation is an idiopathic chronic tumor-like inflammation process that usually affects the orbital tissues of both eyes. Isolated optic nerve involvement by an idiopathic inflammatory process is a rare finding. Here, we report a patient with unilateral sudden onset severe orbital pain and headache with visual loss to no light perception that could only be attributed to perineuritis. Radiological findings enabled making the correct diagnosis. Various relevant diagnoses are also discussed...

Pancreatic cancer is one of the most aggressive cancers. The vast majority of patients are diagnosed with advanced, unresectable disease because of early invasive growth and metastatic spread. The aim of this study was to examine YB-1 expression in pancreatic cancer and determine its effects on cell invasion. YB-1 is overexpressed in pancreatic cancer cell lines and patient tissue samples. In patient tissues, high YB-1 levels correlated with perineural invasion. Silencing of YB-1 significantly reduced cell invasion with decreased expression of MMPs in vitro...

Despite advances in oncologic and imaging technology, pancreatic ductal adenocarcinoma remains a highly deadly disease. The only curative option, pancreaticoduodenectomy or pancreatectomy, carries a significant morbidity. Current imaging plays a role in pre-operative staging to determine the probability of achieve disease-free margins. However, a small but not insignificant number of pancreatic cancers have a relatively higher aggressive biology, despite being resectable based on traditional criteria. Recently, imaging biomarkers that serve as a surrogate for tumors with such aggressive phenotype have been described...

Tumour budding in colorectal cancer is an important prognostic factor. A recent consensus conference elaborated recommendations and key issues for future studies, among those the use of pan-cytokeratin stains, especially in stage II patients. We report the first prospective diagnostic experience using pan-cytokeratin for tumour budding assessment. Moreover, we evaluate tumour budding using pan-cytokeratin stains and disease-free survival (DFS) in stage II patients. To this end, tumour budding on pan-cytokeratin-stained sections was evaluated by counting the number of tumour buds in 10 high-power fields (0...

BACKGROUND: Lymph node metastasis (LNM) has a strong influence on the prognosis of patients with early gastric cancer (EGC). As minimally invasive treatments are considered appropriate for EGC, and lymphadenectomy may be restricted or even eliminated in some cases; it is imperative to identify the main risk factors for LNM to individualize the therapeutic approach. This study aims to evaluate the risk factors for LNM in EGC and to determine the adequacy of the endoscopic resection criteria in a western population...
