Article Synopsis
  • Fine needle aspiration (FNA) is a key method for diagnosing salivary gland lesions, and the modified MSRSGC helps standardize FNA report classifications.
  • In a study of 325 patients treated from 2012 to 2019, the sensitivity of the modified MSRSGC was 64.18%, and its specificity was 91.94%.
  • The use of frozen sections (FS) primarily aimed to establish a primary diagnosis, mostly showing malignancy when FNA results were classified as type V or higher, indicating that FS may not significantly enhance intraoperative decision-making.

Article Synopsis
  • - The study evaluates how well computed tomography (CT) can predict extrathyroidal extension (ETE) and tracheal invasion (TI) in patients with differentiated papillary thyroid carcinoma (PTC), comparing its accuracy to that of ultrasound (US).
  • - Data was collected from 83 patients who had both US and CT scans before surgery, focusing on the diagnostic performance based on sensitivity, specificity, and predictive values for detecting ETE and TI.
  • - Results indicate that while CT is fairly accurate and specific for ETE, its sensitivity is lower than that of US, implying that CT alone may not be sufficient for conclusive assessments in some cases.

Background: Spindle cell lipomas (SL) and pleomorphic lipomas (PL) are rare variants of lipomas, occurring predominantly in the head and neck region. Laryngeal SL/PL is very uncommon and causes obstructive symptoms needing immediate intervention. These tumors are often challenging in radiology due to the admixture of elements and the presence of adipose tissue may help in diagnosis.

Introduction: Thyroglossal duct cyst (TGDC) is the most frequently encountered developmental anomaly in thyroid genesis with a reported incidence of 7% in the adult population. The cyst is known to develop anywhere along the pathway of thyroid descent but is more frequently seen in the infrahyoid neck in the midline. The incidence of malignancy in a TGDC is approximately 1%; a majority of these are papillary carcinomas.

Objective: Interpreting complex post-treatment changes in head and neck cancer (HNC) is challenging with further added perplexity due to variable interobserver interpretation and hence evolved the NI-RADS lexicon. We evaluated the accuracy of NI-RADS in predicting disease status on 1st post-treatment follow-up CECT in a homogenous cohort of those who received only chemoradiation.

Methods: Retrospective analysis of imaging was done for LASHNC patients who received radical chemoradiation in an open-label, investigator-initiated, phase 3 randomized trial (2012-2018) randomly assigned to either radical radiotherapy with concurrent weekly cisplatin (CRT) or CRT with the same schedule plus weekly nimotuzumab (NCRT).

Context.—: Human epidermal growth factor (HER2/neu) gene amplification, a poor prognostic factor in invasive breast cancer, has shown substantial utility as a predictive marker, with significantly improved survival following anti-HER2 therapies like trastuzumab. Dual-color dual in situ hybridization (D-DISH), a recently introduced fully automated assay for HER2/neu evaluation on light microscopy, has several advantages over fluorescence in situ hybridization (FISH).

Background: Gingivobuccal complex oral squamous cell carcinoma (GBC-OSCC) is an aggressive malignancy with high mortality often preceded by premalignant lesions, including leukoplakia. Previous studies have reported genomic drivers in OSCC, but much remains to be elucidated about DNA methylation patterns across different stages of oral carcinogenesis.

Results: There is a serious lack of biomarkers and clinical application of biomarkers for early detection and prognosis of gingivobuccal complex cancers.

Despite advancements in technology and increase in favorable outcomes associated with oral cancer, early detection remains the most significant factor in limiting mortality. The current study aimed to develop early diagnostic and prognostic markers for oral tumorigenesis. Protein and ultrastructural alterations at cell-extracellular matrix (ECM) adhesion junctions were examined concurrently using immunohistochemistry (IHC) and transmission electron microscopy (TEM) on progressive grade of oral carcinomas (n = 285).

Objective: Histoplasmosis is a systemic, deep mycotic infection caused by Histoplasma capsulatum. Disseminated histoplasmosis (DH) is synonymous with HIV seropositive immunocompromised individuals; however, isolated histoplasmosis involving the head and neck mucosal sites mimicking malignancy is a clinical predicament. The result, in a superficial biopsy with marked pseudoepitheliomatous hyperplasia (PEH), in a tertiary care cancer center where the number of squamous carcinomas far outnumber the infectious diseases, could be catastrophic.
