Diagnostic value of silver nitrate staining for nucleolar organizer regions in selected head and neck tumors.

BACKGROUND The present study is aimed to assess the usefulness of silver nitrate staining of nucleolar organizer regions (NORs) as a quantitative criterion for the diagnosis of selected head and neck tumors. MATERIALS AND METHODS The silver nitrate staining technique was used on 195 paraffin blocks collected from 85 patients. The samples consisted of 21 squamous cell carcinoma (SCC) of larynx...

Diagnostic Value of Proliferatin Index Including MIB1 and Argyrophilic Nucleolar Organizer Regions Proteins in Uterine Smooth Muscle Tumors

  Background and Objectives: Uterine smooth muscle tumors are the most common human neoplasm .They are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (STUMP) and differentiation  of these tumors on the basis of H&E staining is impossible .

Fractal Analysis and the Diagnostic Usefulness of Silver Staining Nucleolar Organizer Regions in Prostate Adenocarcinoma

Pathological diagnosis of prostate adenocarcinoma often requires complementary methods. On prostate biopsy tissue from 39 patients including benign nodular hyperplasia (BNH), atypical adenomatous hyperplasia (AAH), and adenocarcinomas, we have performed combined histochemical-immunohistochemical stainings for argyrophilic nucleolar organizer regions (AgNORs) and glandular basal cells. After asc...

diagnostic value of silver-stained nucleolar organizer regions in osteosarcoma, fibrous dysplasia and ossifying fibroma of the jaws

it is sometimes difficult to recognize a jaw lesion as osteosarcoma, ossifying fibroma or ‎fibrous dysplasia in routine hematoxylin and ‎eosin staining and a more accurate technique is needed to differentiate these ‎lesions. ‎many studies have shown the potential usefulness of silver-stained nucleolar organizer region (agnor) parameters for the diagnosis of various neoplasms. this study was car...
