Among oral lesions, we encounter a series of malignant epithelial lesions that go through clinical and histopathologic processes in order to be diagnosed. Identifying these processes along with the etiology knowledge of these lesions is very important in prevention and early treatments. Dysplasia is the step preceding the formation of squamous cell carcinoma in lesions which have the potential ...

Background: Oral lesions can affect people’s quality of life by interfering with chewing, swallowing, and speech. These may originate from epithelial or mesenchymal tissues. Malignant oral be life-threatening. Epidemiological data in Iran is limited. Objective: This study aims to investigate the frequency Rasht, Iran. Methods: In this cross-sectional study, histopathologic reported Razi laborat...

Purpose: Dynamic contrast-enhanced (DCE)-MRI has a promising role in breast cancer detection and lesion characterisation. Diffusion-weighted imaging (DWI) acts as an adjunct the differentiation between benign malignant lesions. The purpose of study was to evaluate efficacy DCE-MRI DWI differentiating Methods: In prospective conducted March 2019 February 2020, 60 patients with lesions underwent ...

Objective: The aim of this study was to determine whether the suggested threshold ADC measurements can be used to characterize benign and malignant breast lesions. Materials and Methods: Sixty two female patients between the ages of 15-64 years (mean age, 44 years) with 49 benign and 25 malignant histopathologically verified breast masses were included in this study. The patients were examined ...

This study determined the presence of human papillomavirus (HPV) DNA in oral mucosa cells from 121 patients with different types of oral mucosal lesions (13 squamous cell carcinomas, 59 potentially malignant lesions, 49 benign erosive ulcerative lesions) and from 90 control subjects. HPV DNA was detected by nested polymerase chain reaction, and genotype was determined by DNA sequencing. HPV pre...

Abstract Background Urinary bladder tumors are the most common type of detected in patients with gross hematuria. Multidetector computed tomography (MDCT) is an accurate method for detecting lesions. This review aims to describe features MDCT and possible values distinguishing these lesions bladder. Main body In this review, we discuss role evaluation cancer a broad spectrum lesions, including ...

The aim of the present study was to investigate the significance and values of 3.0T diffusion weighted imaging (DWI) to differentially diagnose benign and malignant space-occupying liver lesions. A total of 91 patients with liver space-occupying lesions (145 lesions) were admitted into Zhongnan Hospital of Wuhan University (Wuhan, China) from November 2015 to May 2016. Routine scanning, DWI and...

BACKGROUND Percutaneous transthoracic needle biopsy is used in the diagnosis of pulmonary and pleural lesions. The standard procedure using the Vacu-Cut cutting type of needle is the "thrust" technique in which the needle is rapidly forced through the lesion. In our experience this technique has a low yield of histological biopsy specimens. The diagnostic yield of a new biopsy technique ("drill...
