Purpose: Ultrasound-guided fine-needle aspiration cytology (FNAC) is a widely used diagnostic procedure which facilitates the differentiation of salivary gland lesions. Although the performance of salivary gland FNAC (SG-FNAC) has improved since the introduction of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC), the range of the reported performance is still wide. Therefore, the aim of this study was to determine lesion- and sampling-related factors that influence the success of SG-FNAC.

Salivary gland carcinomas are a rare and heterogeneous group of malignant tumors, accounting for 3-6% of all malignant tumors in the head and neck region. The 1-, 3- and 5-year survival rates are 83%, 69% and 63% respectively. Due to new molecular pathological and genetic findings, new entities are constantly being defined as part of the recurring WHO classification of salivary gland carcinomas, so that the incidence rates of the entities are subject to constant change.

- This study analyzes the epidemiology of paranasal sinus cancer (PSC) in Germany, focusing on its incidence, staging, clinicopathological features, and survival rates using data from a major cancer registry.
- Over 3,975 PSC cases were examined, revealing a low and stable age-adjusted incidence rate of 0.3 per 100,000, with the maxillary sinus being the most common tumor site and keratinizing squamous cell carcinoma as the predominant type.
- The study found that the overall 5-year relative survival rate was 52%, significantly decreasing with higher T, N, and M stages, indicating worse outcomes for advanced cancer stages.
Background: Primary salivary gland carcinomas (SGC) are rare neoplasms that present therapeutic challenges especially in recurrent tumors. The aim of this study was to investigate the incidence and distribution of tumor recurrence, associated risk factors, and survival.
Methods: This analysis includes data from 318 patients treated for SGC between 1992 and 2020.
Background: A parotid abscess (PA) is a complication of an acute bacterial parotitis with a potentially life-threatening course. To date, data on the diagnosis and therapy of PA is sparse and mostly consists of case reports or case series. Therefore, this study aimed at comprehensively analyzing the microbiological spectrum and the therapeutic management in a bi-institutional setting.
