A systematic review of the clinicopathological characteristics of oral leiomyomatous hamartoma.

Background: Oral leiomyomatous hamartoma (OLH) corresponds to an abnormal, benign and disorganized overgrowth of mature smooth muscle tissue, which can develop in any site where this tissue is found in healthy conditions. The present systematic review aimed to analyze the clinicopathological characteristics of OLH.

Materials And Methods: The protocol of this study was constructed following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was registered in the Open Science Framework (OSF): OSF.

Transformation zone at the vallate papillae: a significant source of papillomavirus infection at the base of the tongue?

Objective: The aim of this study was to investigate whether the base of the tongue harbours a transformation zone (TZ), i.e., an initiation site for papillomavirus infection, analogous to that in the uterine cervix by examining the histological structure of Von Ebner's gland ducts in the vallate papillae.

Targeted RNA Sequencing of Head and Neck Adenoid Cystic Carcinoma Reveals SEC16A::NOTCH1 Fusion and MET Exon 14 Skipping as Potentially Actionable Alterations.

Purpose: Adenoid cystic carcinoma (AdCC) of the head and neck harbors MYB/MYBL1::NFIB fusions in around 60% of cases, with unfavorable long-term survival due to frequent recurrences and metastases, currently lacking effective targeted therapy. The study aims to identify actionable alterations and to elucidate the molecular underpinnings of MYB/MYBL1::NFIB-negative AdCC using a large targeted RNA sequencing panel.

Methods And Results: We retrospectively searched our MSK-Solid Fusion clinical sequencing database for head and neck AdCC sequenced between 2016 and 2023.

A case report on lingual schwannoma.

Schwannomas are benign tumours of peripheral nerves originating in the nerve sheaths. Only 1% are reported in the oral cavity. We report a 24-year-old female who presented with a 10-year history of a mass at the base of the tongue with associated odynodysphagia, referred otalgia and loss of weight.

[Indications and early experience with transoral robotic surgery].

Recently, organ preservation has gained importance for head and neck malignancies. The negative consequences of the therapies can be reduced without compromising the survival and the quality of life. Accordingly, transoral robotic surgery (TORS) is gaining ground internationally.

Evaluation of the attributable fraction and burden of HPV-related oropharyngeal cancers in Greece-the ORPHEAS study.

Background: Herein, we evaluated the attributable fraction (AF) of human papillomavirus (HPV)-mediated (HPV+) oropharyngeal carcinomas (OPCs) in Greece over a recent calendar period.

Patients And Methods: ORPHEAS, a retrospective, observational, multicenter, cross-sectional study with prospective recruitment, included adult patients with OPC in 2017-2022, each of them with a high-quality, treatment-naïve tumor specimen. The primary endpoint was the HPV-AF, defined as combined positivity for p16 (p16) overexpression and HPV DNA presence by central laboratory testing, among included patients.

Adolescent tongue base tumour with diagnostic histopathological dilemma.

Mucoepidermoid carcinoma arising from minor salivary glands at the base of the tongue is rare. Surgical excision of the tumours remains the primary treatment of choice. The prognosis of this tumour depends on optimum clearance of the disease surgically, clinical staging and histopathological grading.

Effects of chemoradiation and tongue exercise on swallow biomechanics and bolus kinematics.

Background: Common treatments for head and neck cancer (radiation and chemotherapy) can lead to dysphagia; tongue exercise is a common intervention. This study aimed to assess swallow biomechanics and bolus kinematics using a well-established rat model of radiation or chemoradiation treatment to the tongue base, with or without tongue exercise intervention.

Methods: Pre- and post-treatment videofluoroscopy was conducted on 32 male Sprague-Dawley rats treated with radiation/chemoradiation and exercise/no exercise.

Malignant Epithelioid Mesenchymal Neoplasm with FUS::CREM Gene Fusion Arising in the Tongue: A Case Report Detailing Clinicopathological, Imaging, and Molecular Features.

FUS::CREM fusion is a distinct primary driver in rare neoplasms of the head and neck and other anatomic sites. Herein, we describe the clinicopathological, imaging, and molecular features of a malignant epithelioid mesenchymal neoplasm harboring FUS::CREM fusion, arising in the tongue of a 46-year-old male. Clinically, the patient presented with a left upper neck mass.

The prognostic role of MRI-based radiomics in tongue carcinoma: a multicentric validation study.

Purpose: Radiomics is an emerging field that utilizes quantitative features extracted from medical images to predict clinically meaningful outcomes. Validating findings is crucial to assess radiomics applicability. We aimed to validate previously published magnetic resonance imaging (MRI) radiomics models to predict oncological outcomes in oral tongue squamous cell carcinoma (OTSCC).
