Article Synopsis
  • Synovial sarcoma (SS) is a rare type of cancer, primarily found in genitourinary tissues, commonly linked to the SS18::SSX gene fusion, and its paratesticular occurrence is extremely uncommon, with only 4 documented cases prior to this study.
  • This research details the characteristics and genetic profile of the largest cohort of paratesticular SS patients, analyzing data from 14 individuals aged 15 to 47, all of whom underwent surgical removal of the tumors and some received chemotherapy.
  • The findings indicate a generally poor prognosis for paratesticular SS even after aggressive treatment, emphasizing the need for thorough diagnostic methods to differentiate it from similar conditions, and supporting the use of SS18-SS

Juxtaglomerular cell tumor (JGCT) is a rare neoplasm, part of the family of mesenchymal tumors of the kidney. Although the pathophysiological and clinical correlates of JGCT are well known, as these tumors are an important cause of early-onset arterial hypertension refractory to medical treatment, their molecular background is unknown, with only few small studies investigating their karyotype. Herein we describe a multi-institutional cohort of JGCTs diagnosed by experienced genitourinary pathologists, evaluating clinical presentation and outcome, morphologic diversity, and, importantly, the molecular features.

Prostate cancer is heterogeneous with varied pathologic features and presents with a wide spectrum of clinical manifestations from indolent to advanced cancer. Interrogation of the molecular landscape of prostate cancer has unveiled the complex genomic alterations in these tumors, which significantly impacts tumor biology. The documented array of chromosomal alterations, gene fusions, and epigenetic changes not only play a crucial role in oncogenesis and disease progression, but also impacts response and resistance to various therapeutic modalities.

Multifocal ganglioneuromas are characterized by the presence of multiple benign neuroepithelial tumor nodules and are less common than solitary tumors. A small percentage of ganglioneuromas present with a fatty appearance. Only a few cases of multifocal ganglioneuromas have been reported, due to both their rarity and minimal symptomatic presentation; therefore, generalizations about risk factors and predictive markers are very difficult.

Nested urothelial carcinoma (NUC) and large nested urothelial carcinoma (LNUC) of the upper urinary tract are exceedingly rare. This has contributed to the paucity of information regarding their clinicopathological and molecular characteristics. To address this knowledge gap, we explored the largest cohort to date of these rare tumors, comprising resection specimens of 10 LNUC and 7 NUC, from 7 participating institutions.

Article Synopsis
  • Renal cell carcinoma (RCC) is a common cancer, with clear cell RCC (ccRCC) being the most prevalent subtype, and understanding its tumor immune microenvironment (TIME) is crucial for treatment decisions.
  • This study explores using radiomics from CT scans as a noninvasive way to assess CD68 tumor-associated macrophages (TAMs), which are important in ccRCC's TIME, instead of traditional time-consuming tissue-based methods.
  • The research yielded promising results, with models achieving good accuracy in predicting TAM population and clustering, indicating that CT-derived imaging markers could enhance patient monitoring and inform targeted therapies for ccRCC.

Article Synopsis
  • The study evaluates the effectiveness of two antibodies, SPT24 and 8G7G3/1, in distinguishing between pulmonary and nonpulmonary small cell carcinomas.
  • All examined pulmonary small cell carcinomas showed positive staining for both antibodies, while nonpulmonary types had varied results, with significant differences in staining levels between the two antibodies.
  • The findings highlight that while pulmonary carcinomas show strong and consistent staining, nonpulmonary cases demonstrate less staining, but these results should be interpreted along with clinical and imaging data for accurate diagnosis.

Primary female urethral carcinoma (PUC-F) accounts for less than 1% of all genitourinary malignancies and comprises a histologically diverse group of tumors that are usually associated with poor prognosis. The carcinomas documented at this site include adenocarcinoma (clear cell adenocarcinoma, columnar cell carcinoma, and Skene gland adenocarcinoma), urothelial carcinoma (UCa), and squamous cell carcinoma (SCC). Recent studies have shown adenocarcinomas to be the most common type of primary urethral carcinoma in females.
