Decoding the Genetics of Recurrent Molar Pregnancy.

Hydatidiform mole is a condition characterised by abnormal trophoblastic hyperplasia and failure of embryonic tissue development. The risk of recurrence is seen to be associated with biallelic maternal mutations in , and genes. Women with such mutations have a major risk of reproductive failure and normal pregnancy is seen in only 1.

Low-grade oncocytic tumour of the kidney is characterised by genetic alterations of TSC1, TSC2, MTOR or PIK3CA and consistent GATA3 positivity.

Low-grade oncocytic tumour (LOT) of the kidney has recently emerged as a potential novel tumour type. Despite similarity to oncocytoma or eosinophilic chromophobe renal cell carcinoma, it shows diffuse keratin 7 immunohistochemistry (IHC) and negative KIT (CD117), which differs from both. We aimed to identify the molecular characteristics of these tumours.

Comparison of epidermal growth factor receptor mutation detection turnaround times and concordance among real-time polymerase chain reaction, high-throughput next-generation sequencing and the Biocartis Idylla™ platforms in non-small cell lung carcinomas.

Objectives: Activating mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) gene of non-small cell lung carcinomas (NSCLC) can be targeted by the tyrosine kinase inhibitors. A number of molecular diagnostic platforms are used to detect actionable targets in the exon(s) 18, 19, 20, and 21 of the EGFR gene. The Idylla™ system (Biocartis, Mechelen, Belgium) is a relatively novel technique and is unique in integrating both sample processing and real-time polymerase chain reaction (RT-PCR) in a single cartridge.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and coronavirus disease 19 (COVID-19) - anatomic pathology perspective on current knowledge.

Background: The world is currently witnessing a major devastating pandemic of Coronavirus disease-2019 (COVID-19). This disease is caused by a novel coronavirus named Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). It primarily affects the respiratory tract and particularly the lungs.

Xanthogranulomatous Orchitis Presenting as a Scrotal Mass in an Elderly Male: Malignancy or Mimicker?

Xanthogranulomatous inflammation is a rare, destructive pattern of inflammation, affecting different organs, that often produces a mass-like lesion, simulating malignancy. Although benign, it can coexist with malignancy. We, herein, report the case of a 60-year-old male patient, who presented with a testicular mass that was partly necrotic and showed heterogeneous enhancement on contrast study.
