Background: Perineural invasion (PNI) by primary cutaneous cancers is an important adverse risk factor. Certain benign conditions may mimic microscopic PNI. Mohs surgery is being performed more frequently on smaller primary cutaneous malignancies. While PNI may be present in these cases, it is likely to be microscopic and asymptomatic, affecting as little as one cutaneous nerve branch.
Methods: Review of the literature base regarding PNI as well as contribution of original findings.
Results: Four benign entities that could easily be confused with microscopic PNI are presented.
Conclusion: At least four benign mimics of microscopic PNI exist, important in the differential diagnosis of microscopic PNI. Knowledge of these entities should help dermatopathologists to correctly distinguish them from PNI and avoid unnecessary additional treatment.

Background And Objectives: Patients with chronic kidney disease (CKD) are at increased risk of severe COVID-19 outcomes due to their compromised immune systems and chronic inflammatory state. This study aimed to evaluate and compare the inflammatory status of COVID-19 patients with CKD, stratified by creatinine clearance (CrCl) levels: CrCl < 30 mL/min, CrCl 30-60 mL/min, and CrCl > 60 mL/min. Multiple inflammatory scores combining laboratory parameters were assessed, including novel scores and established indices.

Background: Depth of invasion (DOI) significantly influences prognosis and treatment strategies in oral squamous cell carcinoma (OSCC). Accurate preoperative imaging, such as contrast-enhanced computed tomography (CECT), alongside postoperative histopathological evaluations, aids in determining DOI. This study evaluates the correlation between radiological DOI (rDOI), macroscopic DOI (PDOI), and microscopic DOI (pDOI) in OSCC.

Background: This short review and pictorial essay presents a morphological insight into cancer neuroscience, which is a complex and dynamic area of the pathobiology of tumors.
Methods: We discuss the different methods and issues connected with structural research on tumor innervation, interactions between neoplastic cells and the nervous system, and dysregulated neural influence on cancer phenotypes.
Results: Perineural invasion (PNI), the most-visible cancer-nerve relation, is briefly presented, focusing on its pathophysiology and structural diversity as well as its clinical significance.

Background: Treating peripheral nerve injuries (PNI) with defects remains challenging in clinical practice. The commercial conduits have shown suboptimal nerve regeneration and functional recovery due to their basic tubular design without electroactive and oriented topographical cues.
Purpose: To develop a new scaffold with oriented microstructure and electroactive Graphene oxide (GO) and investigate its' therapeutic effect on nerve regeneration in vitro and in vivo.

The objective of this study was to investigate the relationship between mortality and the prognostic nutritional index (PNI) in the pediatric patient group with ventriculoperitoneal shunt (VPS) infection. A total of 63 pediatric patients with a VPS infection and positive cerebrospinal fluid (CSF) culture were retrospectively registered. The CSF specimens were analyzed to conduct culture and microscopic evaluation.
