Prostate adenocarcinoma with Paneth cell-like neuroendocrine differentiation is a rare entity. Foci of scattered cells and small clusters are found in the majority of described cases, although cases with predominant Paneth cell-like features have also been recorded. These cells contain eosinophilic cytoplasmic inclusions and lack androgen receptors, and are consequently immune to hormone therapy. It is, therefore, important for pathologists to recognize them. According to literature, clinical outcome depends on the standard grading of the conventional prostate cancer component. We report a case of a 54 year-old patient with prostatic adenocarcinoma showing Paneth cell-like neuroendocrine differentiation.

Article Synopsis
- The study investigates the occurrence of rete hyperplasia and hyaline globules in germ cell tumors, with a focus on their potential to mimic yolk sac tumors, noting a significant misdiagnosis risk over the years.
- Out of 348 evaluated orchiectomies, 30% showed rete hyperplasia and/or hyaline globules, often without any yolk sac tumor component, suggesting a complexity in tumor classifications.
- The findings highlight the importance of accurately identifying these histological features, as they may indicate underlying testicular obstruction due to the tumor, which is crucial for proper treatment decisions.
The small intestinal crypts harbor secretory Paneth cells (PCs) which express bactericidal peptides that are crucial for maintaining intestinal homeostasis. Considering the diverse environmental conditions throughout the course of the small intestine, multiple subtypes of PCs are expected to exist. We applied single-cell RNA-sequencing of PCs combined with deep bulk RNA-sequencing on PC populations of different small intestinal locations and discovered several expression-based PC clusters.

Although the role of the intestinal microbiota in the pathogenesis of inflammatory bowel disease (IBD) is beyond debate, attempts to verify the causative role of IBD-associated dysbiosis have been limited to reports of promoting the disease in genetically susceptible mice or in chemically induced colitis. We aimed to further test the host response to fecal microbiome transplantation (FMT) from Crohn's disease patients on mucosal homeostasis in ex-germ-free (xGF) mice. We characterized and transferred fecal microbiota from healthy patients and patients with defined Crohn's ileocolitis (CD_L3) to germ-free mice and analyzed the resulting microbial and mucosal homeostasis by 16S profiling, shotgun metagenomics, histology, immunofluorescence (IF) and RNAseq analysis.
