AIM To evaluate factors that influence the diagnostic accuracy of endoscopic ultrasound (EUS)-guided tissue acquisition for lymph node enlargement in the absence of an on-site pathologist. METHODS A retrospective analysis of patients who underwent EUS-guided tissue acquisition for the pathological diagnosis of lymph node enlargement between April 2012 and June 2015 is reported. Tissue acquisi...

the most common metastatic sites for colorectal carcinomas include the liver, lungs, brain, bones and peritoneal surfaces. in this report, a case of sigmoid colon carcinoma presented with cervical lymphadenopathy was detected with the help of pet/ct. a 57 year-old male presented with a complaint of swelling on the left side of his neck. ultrasonographic examination of the neck revealed three hy...

OBJECTIVE To evaluate the diagnostic assessment of enlarged lymph nodes, based on its perfusion pattern by taking tissue diagnosis as gold standard. STUDY DESIGN Analytical study. PLACE AND DURATION OF STUDY Departments of Radiology and Pathology, PIMS Hospital, Islamabad, from February to May 2016. METHODOLOGY Color sonography of patients with clinically, palpable cervical lymph nodes we...

BACKGROUND As in women, regional lymph node status impacts survival in dogs with malignant mammary tumors. However, few studies have evaluated regional lymph node metastases in dogs with malignant mammary gland tumors. OBJECTIVES To estimate overall survival based on the assessments of the lymph node status and the morphologic and morphometric features in female dogs with malignant mammary gl...

BACKGROUND Lymph node involvement and tumor-induced lymphangiogenesis appear as the earliest features of esophageal squamous cell carcinoma (ESCC), although the molecular regulatory mechanisms involved have remained unclear. Our aim was to investigate the contribution of NF-κB and Notch1 signaling to lymph node involvement and tumor-induced lymphangiogenesis in ESCC. MATERIAL AND METHODS NF-κ...

OBJECTIVE Endobronchial ultrasound elastography is a new technique for describing the stiffness of tissue during endobronchial ultrasound-guided transbronchial needle aspiration. The aims of this study were to evaluate the utility of endobronchial ultrasound elastography for mediastinal and hilar lymph nodes, and to compare the elastographic patterns of lymph nodes with results from endobronchi...

BACKGROUND AND AIMS Routine diagnostic work revealed cell aggregates reminiscent of lymph nodes in the bowel submucosa in occasional cases of chronic inflammatory bowel disease. We therefore investigated whether they fulfill criteria for classification as lymph nodes. METHODS Colon with terminal ileum from a patient with florid Crohn's disease and a colectomy specimen from a patient with ulce...
