Angiogenesis is a critical factor in tumor growth and metastasis, and microvessel density (MVD) was an important parameter for assessing vessels in tumors. However, radiologic assessment of tumor vascularity is not yet well established. In our study, we aimed at investigating the efficacy of contrast-enhanced ultrasonography (CEUS) in exploring the vascularity of the ovarian tumors or tumor-lik...

Introduction/Background Multicenter prospective clinical validation of the radiomic machine learning model (TRACE4OC) applied to transvaginal ultrasound (US) in predicting risk malignancy adnexal masses. Methodology From a multicenter consecutive series women scheduled for surgery masses, we collected and evaluated, fully blinded, 230 preoperative US images masses with TRACE4O...

Metastasis to the stomach from nongastric tumors is a rare event. We present a case of ovarian cancer metastasis to the gastric wall that presented as multiple subepithelial gastric lesions. A 55-year-old female with known stage III b serous ovarian cancer was admitted to the hospital with melena and anemia. A 1.5 to 2 cm subepithelial mass with superficial overlying erosion in the antrum was s...

Clinical observation of skin metastasis in ovarian cancer cases is relatively uncommon. And distant metastatic skin lesions including the extremities are much rarer still as most metastatic skin lesions are located in the skin in the abdominal wall adjacent to where the primary ovarian tumors exist. We report the case of a 60-year-old woman who presented skin lesions on both lower extremities a...

Quantitative aspects of cytology and histology should be considered in diagnostic standardisation processes. The present paper summarises the cytological differences detected in 75 thyroid lesions using a computerized textural analysis. Cells stained with progressive hematoxylin and taken from paraffin blocks were overlaid with the extracted texture. This technique was based on the lineal detec...

 Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary.  Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...
