BACKGROUND: Accurate tissue sampling in nonenhancing (NE) gliomas is a unique surgical challenge due to their intratumoral histological heterogeneity and absence of contrast enhancement as a guide for intraoperative stereotactic guidance. Instead, T2/fluid-attenuated inversion-recovery (FLAIR) hyperintensity on MRI is commonly used as an imaging surrogate for pathological tissue, but sampling from this region can yield nondiagnostic or underdiagnostic brain tissue. Sodium fluorescein is an intraoperative fluorescent dye that has a high predictive value for tumor identification in areas of contrast enhancement and NE in glioblastomas...

BACKGROUND: Due to the obstruction of the surrounding structures or stiff mucosa, the primary and recurrent nonexophytic nasopharyngeal carcinoma (NE-NPC) patients are difficult to be diagnosed histologically by traditional forceps biopsy. RESULTS: All the 15 cases had adequate biopsy for histological diagnosis. There were 5 cases of primary and 7 cases of recurrent NE-NPC, and 3 cases of inflammatory lesion. The histopathological diagnosis was consistent with the follow-up visit...

Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas. Therefore, epigenomics may represent a novel and promising tool for precision medicine, and in particular, the detection of epigenomic biomarkers in liquid biopsies will be of great interest for monitoring diseases in patients...

CONTEXT: - A vast majority of neoplasms arising from lung or pleura are initially diagnosed based on the histologic evaluation of small transbronchial, endobronchial, or needle core biopsies. Although most diagnoses can be determined by morphology alone, immunohistochemistry can be a valuable diagnostic tool in the workup of problematic cases. OBJECTIVE: - To provide a practical approach in the interpretation and immunohistochemical selection of lung/pleura-based neoplasms obtained from small biopsy samples...

BACKGROUND: Intraoperative analysis of lymph nodes during a sentinel lymph node biopsy (SLNB) procedure could result in one-step surgery for early oral squamous cell carcinoma (OSCC) with an occult nodal metastasis. One-step nucleic acid amplification rapidly detects cytokeratin 19 (CK19) RNA with high accuracy. Sensitivity and specificity of CK19 expression in OSCC was evaluated. METHODS: Immunohistochemical CK19 expression was done in 207 patients with OSCC with 65 cases of paired nodal metastases...

AIMS: Surgical excision of all benign vascular lesions of the breast identified by core needle biopsy has been recommended in the past to rule out a more serious lesion. In this study we investigated the clinical, radiologic, and pathologic findings in patients diagnosed with a benign vascular lesion at our institution to assess whether excision may be spared for lesions without atypia. METHODS AND RESULTS: We searched the electronic medical record for patients with a vascular lesion of the breast diagnosed between 2000 and 2015...

Liver biopsy is a valuable tool. Even though outpatient liver biopsies are routinely performed in adults, there are no clear recommendations on its safety and feasibility in children. We reviewed the records of children who underwent a percutaneous liver biopsy at our institution between January 2005 and June 2015. A total of 626 biopsies were performed on 497 patients (250 boys, median age 6 [0.2-19.3] years). Abnormal liver function tests for investigation 288 (46%) was the most common indication. Thirty (4...

OBJECTIVE: Monogenic defects in the interleukin-10 (IL-10) pathway are extremely rare and cause infantile-onset inflammatory bowel disease (IBD)-like pathology. Understanding how immune responses are dysregulated in monogenic IBD-like diseases can provide valuable insight in "classical" IBD pathogenesis. Here, we studied long-term immune cell development and function in an adolescent IL-10 receptor (IL10RA)-deficient patient who presented in infancy with severe colitis and fistulizing perianal disease and is currently treated with immune suppressants...

OBJECTIVES: Celiac disease (CD) and eosinophilic esophagitis (EoE) are underdiagnosed gastrointestinal conditions, which adversely affect children's health. Previous studies have shown that diagnostic guidelines for CD are not consistently followed in adults. The aims of the present study are to assess the frequency with which endoscopists comply with diagnostic guidelines for CD and EoE in children, and to determine whether an association exists between adherence to biopsy guidelines and disease detection in pediatric patients...

INTRODUCTION: Although it is not rare for magnetic resonance imaging findings in Creutzfeldt-Jakob disease to be asymmetric, unilateral clinical syndromes are uncommonly reported and may confound diagnosis. In addition, neurological paraneoplastic syndromes are not common in renal cell carcinoma, though there are cases reported, often without an offending antibody isolated. CASE REPORT: A 66-year-old man was admitted with 1 month of left-sided numbness and "loss of control" of the left arm...

Melanoma is a highly aggressive cancer that represents a significant disease burden, making diagnosis and appropriate control of disease vital for improving morbidity and mortality. The most recent guidelines for melanoma treatment advise performing a sentinel lymph node biopsy for intermediate thickness melanomas, with subsequent completion lymph node dissection (CLND) if sentinel nodes are positive. This guideline is controversial due to the limited availability of data on this topic. CLND is an extensive surgery with known risks and complications and a small survival benefit...
