Histopathologic evaluation of Asian-American patients with chronic rhinosinusitis with nasal polyps.

Asian-American (AA) patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have comparable rates of tissue eosinophilia compared to Caucasians when defined as >10 eosinophils/high-powered field (HPF). AA patients with CRSwNP have significantly higher incidence of mixed inflammation defined as >10 eosinophils/HPF and >10 neutrophils/HPF.

Endotype evaluation of Hispanic/Latinx-American patients with chronic rhinosinusitis with nasal polyps.

Hispanic-American patients with chronic rhinosinusitis with nasal polyps have a comparable level of tissue eosinophilia compared to their Caucasian counterparts in the United States. Mixed inflammation involving both neutrophils and eosinophils is more common in this population compared to Caucasians. Findings from this study may indicate that Hispanic-American patients have a unique endotype or endotypes that deserves further investigation.

Increased Prevalence of Eosinophilic Esophagitis in Patients With Chronic Rhinosinusitis.

Background: Chronic rhinosinusitis (CRS) and eosinophilic esophagitis (EoE) are immune-mediated inflammatory conditions that share common histopathologic features. Once considered two separate pathologies, preliminary data has suggested that a higher prevalence of EoE may exist in patients with CRS.

Objectives: We aimed to expand the base of evidence across geographic regions and investigate the association between EoE and CRS, including CRS with nasal polyposis (CRSwNP).

Angioleiomyoma of the nasolacrimal duct: case report and literature review.

Angioleiomyomas are benign tumors composed of smooth muscle and vascular endothelium. While infrequent in overall prevalence, they are exceptionally rare in the head and neck. Herein, we describe the case of a 65-year-old female who was found to have an angioleiomyoma of the right nasolacrimal duct.

Persistent Trigeminal Artery in Endonasal Resection of Skull Base Tumors: A Systematic Review.

 Primitive persistent trigeminal artery (PTA) is an uncommon embryologic vascular communication between the carotid and basilar arteries, which can be intimately involved by skull base tumors (SBT). Owing to its rarity, skull base surgeons should familiarize themselves with the anatomical variations of PTA to avoid catastrophic complications.  To appraise and summarize the available evidence of PTA involved by SBTs while advocating a standardized algorithm for the surgical planning of these patients.
