Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare variant of breast carcinoma. A 68-year-old female patient presented to the general surgery clinic with pain and swelling in the right breast. A mass was detected in the upper outer quadrant, and a fine-needle aspiration biopsy was performed.

Background: The frequency of genotype 4 hepatitis C virus infection is significantly higher in a city compared to other provinces in Turkey. In this study, we aimed to investigate the epidemiology and risk factors of hepatitis C virus genotype 4 infection in Kayseri province of Turkey.
Methods: A case-control study was conducted with 61 hepatitis C virus genotype 4-infected patients and 71 controls.
Invasive cribriform carcinoma (ICC) is a rare type of a primary breast carcinoma. It is subdivided into two groups as pure and mixed types. There are limited studies comparing the pure and mixed ICC at present.

Type II pneumocytes exclusively secrete 'pulmonary surfactants,' a lipoprotein complex made up of 90% lipids (mainly phospholipids) and 10% surfactant proteins (SP-A, SP-B, SP-C, and SP-D). Respiratory diseases such as influenza, severe acute respiratory syndrome coronavirus infection, and severe acute respiratory syndrome coronavirus 2 infection are reported to preferentially attack type II pneumocytes of the lungs.

Methods: A total of 120 lesions that were performed SE with histopathologically confirmed fibroadenoma were included in the study. All images were reviewed from the archiving system with a consensus of two radiologists.
Purpose: Elastography was primarily used as an adjunctive method along with ultrasonography in differentiation between benign from malignant lesions. Occasionally, overlaps can occur which are caused by some rare invasive breast cancers. Our aim is to analyze the role of rare breast cancers in false negative strain elastography results and to assess the relation among false negative results and tumor size, lesion distance to skin, and tumor grade.

Tumor size is a major determiner of treatment planning, acting on the decision-making process, whether to perform breast surgery or administer neoadjuvant chemotherapy. Imaging methods play a key role in determining the tumor size in breast cancers at the time of the diagnosis.

Results: Patients with IIH ( = 32), migraine patients ( = 34) and control subjects ( = 33) were evaluated.
Aims: As the false-negative rates of axillary ultrasonography (AUS) (21%-48%) are not optimal, the demand for axillary surgery remains even if AUS is negative. The aim of this study is to determine the histopathological and tumor characteristics associated with false-negative AUS results.
Materials And Methods: Patients with normal AUS were divided into two groups as true-negative and false-negative according to the histopathology results of axillary lymph nodes.
Metaplastic breast carcinoma (MBC) is a general term defining a heterogeneous group that includes biphasic lesions, with both malignant epithelial and mesenchymal tissue components. Although its clinical findings are similar to those present in invasive ductal carcinoma, it rarely presents with the findings of inflammatory breast cancer. It is generally seen in the fifth decade.

Materials And Methods: 1875 patients (male, aged; 18-40 years) with LBP were investigated retrospectively. Standard lumbar MRI protocol of sagittal, and axial T1 weighted images (WI) and T2 WI and coronal short tau inversion recovery (STIR) T2 WI were obtained.
Background And Objectives: Glutamine is a nonessential amino acid which improves intestinal mucosal regeneration and absorption. Glutathione is a vital molecule for antioxidant reactions and is synthesized from cystine. The first aim of the study is to measure the plasma glutamine and cystine in children with celiac disease (CD) and compare them with controls.

Aims: Our aim was to show the impact of apparent diffusion coefficient (ADC) values acquired with DWI to differentiate benign and malignant breast lesions.
Objective: The use of mammography (MM) in breast cancer screening programs has been increasing in recent years. Thus, increasing the number of detected nonpalpable breast cancer patients, through early diagnosis and treatment also increased survival rates. In our study, we wanted to share the factors about imaging-guided exicional biopsies for non-palpable breast lesions in postoperative proven breast carcinoma patients.
