Classificatory updates in verrucous and cuniculatum carcinomas: Insights from the 5 edition of WHO-IARC head and neck tumor classification.

The International Agency for Research on Cancer (IARC) and World Health Organization (WHO) collaboratively produce the 'WHO Blue Books' essential tools standardizing the diagnostic process for human cancers. Regular updates in this classification accommodate emerging molecular discoveries, advances in immunohistochemical techniques, and evolving clinical insights. The 5 edition of the WHO/IARC classification of head and neck tumors refines the 'Oral Cavity and Mobile Tongue' chapter, including sections for non-neoplastic lesions, epithelial tumors, and tumors of uncertain histogenesis.

Reinnervated Serratus Free Flap for a Functional Outcome in Tongue Reconstruction: A Surgical Technique Video.

The current benchmark for tongue reconstruction after excision of locally advanced tumors involves the use of free skin or fasciocutaneous flaps, such as the anterolateral thigh flap or forearm free flap. They facilitate the volumetric reconstruction of the tongue, leveraging passive mobility from the remaining native tongue tissue. The challenge in tongue reconstruction surgery remains achieving functional restoration through adequate volume and optimized mobility, using tissue that is both adapted and comparable to native tissue.

Implementing a deep learning model for automatic tongue tumour segmentation in ex-vivo 3-dimensional ultrasound volumes.

Three-dimensional (3D) ultrasound can assess the margins of resected tongue carcinoma during surgery. Manual segmentation (MS) is time-consuming, labour-intensive, and subject to operator variability. This study aims to investigate use of a 3D deep learning model for fast intraoperative segmentation of tongue carcinoma in 3D ultrasound volumes.

A Rare Case of Clear Cell Sarcoma of the Tongue: A Case Report.

Clear cell sarcoma (CCS), previously known as soft tissue melanoma due to similarities with melanoma, is a rare and aggressive neoplasm. This tumor predominantly occurs in the lower limbs and rarely affects the tongue, as well as other head and neck locations. To our knowledge, only five cases have been reported in the English literature.

Foregoing elective neck dissection for elderly patients with oral cavity squamous cell carcinoma.

Objective: Elective neck dissection (END) improves outcomes among clinically node-negative patients with oral cavity squamous cell carcinoma (OCSCC). However, END is of questionable value, considering the potentially higher comorbidities and operative risks in elderly patients.

Methods: A retrospective review of all patients older than 65 years of age who were treated for OCSCC at a tertiary care centre between 2005 and 2020 was conducted.

Squamous cell carcinoma of the mobile tongue in young adults: A Swedish head & neck cancer register (SweHNCR) population-based analysis of prognosis in relation to age and stage.

Increased incidence of squamous cell carcinoma (SCC) of the tongue has been reported in young adults (YA) in several countries since the 1980s and confirmed in later studies. The etiology is unclear, the prognosis has been debated, and conflicting results have been published. Some studies show better survival in young adults than in older patients, some worse, and others no difference.

Primary syphilis with a tongue ulcer mimicking tongue cancer: a case report.

The main symptom in primary syphilis is a small, painless, sore or ulcer called a chancre on the penis, vagina, or around the anus, although chancres can sometimes appear in the mouth or on the lips, fingers, or buttocks. We present the case of a man in his early 60 s with a chief complaint of a painful tongue ulcer. An ulcerated, indurated, and hemorrhagic lesion (23 × 14 mm) was found on the ventral tongue surface, near the oral floor.

The Prevalence of HPV in Oral Cavity Squamous Cell Carcinoma.

Human papillomavirus (HPV) is an important risk factor in a subset of head and neck squamous cell carcinomas (HNSCC), but the association with oral cavity squamous cell carcinomas (OCSCC) remains controversial. This study aimed to identify the prevalence of HPV infection in OCSCC. A systematic search on PubMed and EMBASE was performed, including articles assessing the prevalence of HPV-positive (HPV+) OCSCC published from January 2017 to December 2022.

Cortactin expression in a Norwegian cohort of human papilloma virus negative oral squamous cell carcinomas of the mobile tongue.

Oral squamous cell carcinoma of the tongue (OTSCC) is the most common malignancy among oral squamous cell carcinomas and is frequently associated with an unfavorable prognosis. Local spread and distant metastasis are important causes of poor prognosis in OTSCC. Cortactin amplification and overexpression, a common molecular alteration in oral squamous cell carcinomas, have been linked to invasion and metastasis of tumor cells.

The role of radiomics in tongue cancer: A new tool for prognosis prediction.

Background: Radiomics represents an emerging field of precision-medicine. Its application in head and neck is still at the beginning.

Incidental Finding of a Tongue Schwannoma Mimicking Local Recurrence of Squamous Cell Carcinoma on a Systematic Follow-up 18F-FDG PET/CT.

Schwannomas are usually benign, rare, and slow-growing nerve sheath tumor composed of Schwann cells. They develop in the head and neck area in approximately 25% to 40% of cases, of which 1% in the oral cavity, where the tongue remains the preferred site. Malignant transformation occurs in approximately 8% to 10% cases.

Update from the 5th Edition of the World Health Organization Classification of Head and Neck Tumors: Tumours of the Oral Cavity and Mobile Tongue.

The fifth chapter of the upcoming fifth edition of the 2022 World Health Organization Classification of Tumours of the Head and Neck titled Tumours of the oral cavity and mobile tongue, has had some modifications from the 2017 fourth edition. A new section "Non-neoplastic Lesions", introduces two new entries: necrotizing sialometaplasia and melanoacanthoma. The combined Oral potentially malignant disorders and Oral epithelial dysplasia section in the 2015 WHO has now been separated and submucous fibrosis and HPV-associated dysplasia are also discussed in separate sections.

Downregulated Expression of RIPOR3 Correlated with Immune Infiltrates Predicts Poor Prognosis in Oral Tongue Cancer.

BACKGROUND Tongue cancer is the most prevalent of head and neck squamous cell carcinomas, including base of tongue cancer (BOT) and oral squamous cell carcinoma of the mobile tongue (OTSCC). We aimed to investigate the role of RIPOR3 in tumorigenesis and its development as a potential prognostic biomarker for tongue cancer, especially OTSCC. MATERIAL AND METHODS Associations of expression, clinical pathologic features, and overall survival were analyzed by logistic regression, multivariate Cox analysis, and Kaplan-Meier methods.

Objective: The objective of this study was to evaluate the immunoexpression profiles of breast cancer 1 (BRCA1) and acetyl-histone H3 (AcH3) in squamous cell carcinoma of the mobile tongue (SCC-MT) and their correlation with epidemiologic data and the histopathological grade of tumors.

Study Design: Incisional biopsies of 43 SCC-MT were submitted to immunohistochemistry for AcH3 and BRCA1. Samples were microscopically graded as well differentiated (n = 21) or poorly differentiated (n = 22).

[Mobile Thrombus in the Ascending Aorta Detected Incidentally in the Patient with Fever before Surgery for Esophageal Cancer:Report of a Case].

A mobile thrombus in the ascending aorta is extremely rare. A 57-year-old man was referred to our hospital with suspected esophageal cancer. Following thorough evaluation, he was diagnosed with esophageal cancer( UtMt type0-Ⅱa T1b, Mt type0-Ⅱc T1a N0M0 cStageⅠ) and tongue cancer in situ.

Autonomization of pectoralis major flap in head and neck surgery.

The pectoralis major flap (PMF) is one of the most used pedicled flaps for reconstructive surgery in head and neck. Basing on previous studies observing that a vascular accident or pedicle ligation not always resulted in necrosis of free flaps, sometimes after a short critical period, we describe the possibility to perform the division of the PMF pedicle. The autonomization of PMF is based on the hypothesis that the flap, after a critical period, develops a neoangiogenesis at the free portion in the recipient site.

Tongue: the unusual site in malignant pleural mesothelioma.

Malignant mesotheliomas (MMs) are malignancies of the mesothelium, with primary deposits originating in the pleura, peritoneum, pericardium and the tunica vaginalis (ie, testicular). Metastatic spread is commonly reported to affect the liver, adrenal glands, kidney and contralateral lung (in cases of malignant pleural mesothelioma). Metastases to distant sites are uncommon.
