Retroperitoneal teratomas are rare neoplasms in neonates, presenting with nonspecific symptoms and variable clinical features, making diagnosis challenging. Radiological investigations, particularly fetal ultrasound and contrast-enhanced computed tomography, play a critical role in their detection. Differential diagnoses include neuroblastoma, adrenal hemorrhage, and congenital cystic lesions, which share overlapping clinical and imaging features.

Objective: To investigate the ability of the estimated plasma gene-expression levels of microRNA (miR)-21 and 126 to define patients suspected to have hepatocellular carcinoma (HCC) among patients with complicated hepatitis-C virus (HCV) infection.
Methods: Patients with uncomplicated (U-HCV) or complicated HCV underwent clinical and ultrasonographic (US) evaluations and assessment for the computerized hepatorenal index, hepatic steatosis index and fibrosis indices. Blood samples were obtained for estimation of serum levels of alpha-fetoprotein (AFP) and tumor necrosis factor-α (TNF-α), and plasma expression levels of miR-21 and miR-126 using the quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR).
Introduction: Gastric adenocarcinoma with enteroblastic differentiation (GAED) is a rare entity with worse prognosis compared to conventional gastric adenocarcinomas. Its histological characteristics are fetal gut-like architecture and tumor cells with cytoplasmic clearing, as well as positive immunohistochemical reaction to at least one of the enteroblastic markers. Hereby, we present a case of GAED with neuroendocrine marker positivity, with whole exome sequencing (WES), and an updated literature review.

A 28-year-old male presented to his physician with a chief complaint of fever and cough. Contrastenhanced computed tomography revealed a 17×16×8 cm heterogeneous tumor in the anterior mediastinum, as well as right heart and inferior vena cava compression due to the tumor. He was referred to our hospital for close examination and treatment.

Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality globally due to HCC late diagnosis and limited treatment options. MiRNAs (miRNAs) emerged as potential biomarkers for various diseases, including HCC. However, the value of miRNA-101 as a serum biomarker for HCV-induced HCC has not been fully investigated.
