Malignant Mesothelioma of the Tunica Vaginalis: About a Rare Clinical Case.

Malignant mesothelioma (MM) of the tunica vaginalis is an exceedingly rare neoplasm, with fewer than 300 cases reported in the medical literature. Due to its rarity, epidemiology, and risk factors are still unclear, and it is unknown whether asbestos or chronic inflammatory conditions play a role in etiology. This case study presents a 70-year-old male patient with MM of the tunica vaginalis, detailing the diagnostic challenges, treatment procedures, and eventual progression to palliative care.

Radiologic-pathologic correlation of prostatic cancer extracapsular extension (ECE).

Recent advancements on nerve-sparing robotic prostatectomy allow fewer side effects such as urinary incontinence and sexual dysfunction. To perform such techniques, it is essential for the surgeon to know if the neurovascular bundle is involved. Despite being the gold-standard imaging method for Prostate Cancer (PCa) staging, Magnetic Resonance Imaging (MRI) lacks high specificity for detecting extracapsular extension (ECE).

Early biomarkers of extracapsular extension of prostate cancer using MRI-derived semantic features.

Background: To construct a model based on magnetic resonance imaging (MRI) features and histological and clinical variables for the prediction of pathology-detected extracapsular extension (pECE) in patients with prostate cancer (PCa).

Methods: We performed a prospective 3 T MRI study comparing the clinical and MRI data on pECE obtained from patients treated using robotic-assisted radical prostatectomy (RARP) at our institution. The covariates under consideration were prostate-specific antigen (PSA) levels, the patient's age, prostate volume, and MRI interpretative features for predicting pECE based on the Prostate Imaging-Reporting and Data System (PI-RADS) version 2.

Clinical implications of the American Joint Committee on Cancer (AJCC) 8th edition update in seminoma pT1 subclassification.

Background: Seminoma accounts for 30-50% of testicular germ cell tumors (TGCT)-the most common solid malignancy in men aged 15-35 years. The American Joint Committee on Cancer (AJCC) 8th edition (2018) created the subclassifications pT1a (tumor size < 3 cm) and pT1b (≥ 3 cm), despite not being universally recognized. Rete testis invasion (RTI) and tumor size > 4 cm are considered features associated with a higher recurrence risk, but not formally used for staging.
