Objective: To evaluate the utility of diffusion-weighted-imaging (DWI) and apparent-diffusion-coefficient (ADC) in a 3T magnetic-resonance-imaging (MRI) study of breast cancer. In particular, the study aims to classify ADC-values according to histology either for benign or malignant lesions.
Methods: 110 Breast MRI with MRI-DWI sequences and quantitative evaluation of the ADC were retrospectively reviewed. Results obtained with MRI-DWI and with biopsy were analyzed and ADC values were compared to histological results.
Results: MRI showed a 95.5% sensitivity and a 83.7% specificity. The mean ADC values of benign and malignant lesions were 2.06 ± 0.19 and 1.03 ± 0.07 mm(2)/s, respectively (p < .05).
Conclusions: DWI and ADC-values could help distinguishing malignant and benign breast masses.

Introduction: Pseudotumors are benign lesions which may mimic like a malignant tumor on conventional imaging. They are formed in kidneys which are scarred and deformed by chronic pyelonephritis, glomerulonephritis, trauma or infarction. There is a diagnostic dilemma in most of the cases as to differentiate RCC and pseudotumors.

Background: Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, is a type of malignant mesenchymal tumor (sarcoma) of soft tissue and sometimes bone. It is uncommon in the oral cavity and very sporadic in the maxillary sinus. Microscopic diagnosis of this malignancy in the maxillary sinus can be very challenging, because there is a range of features that may overlap with other benign and malignant tumors.

Background: Despite extensive analysis, the dynamic changes in prostate epithelial cell states during tissue homeostasis as well as tumor initiation and progression have been poorly characterized. However, recent advances in single-cell RNA-sequencing (scRNA-seq) technology have greatly facilitated studies of cell states and plasticity in tissue maintenance and cancer, including in the prostate.
Methods: We have performed meta-analyses of new and previously published scRNA-seq datasets for mouse and human prostate tissues to identify and compare cell populations across datasets in a uniform manner.

Background: Endoscopic surgery provides good cosmetic results while ensuring therapeutic outcomes. This study aimed to evaluate the efficacy, safety, and cosmetic outcome of endoscopic surgery for benign breast tumors.
Methods: In total, 108 patients were enrolled and divided into endoscopic or open surgery groups based on the patients' voluntary decisions.

Background: Aurora kinase A (AurkA) plays a vital role in mitosis and is therefore critical in tumors development and progression. There are a few studies on AurkA expression in salivary gland tumors. The aim of the present study was to evaluate the expression pattern of AurkA in the most common benign and malignant salivary gland tumors by immunohistochemistry.
