AI Article Synopsis
- The study examined the incidence and prevalence of salivary gland tumors in Valparaíso, Chile, based on records from 2000 to 2011.
- Most tumors (70.3%) were benign, with pleomorphic adenoma being the most common type (53.8%), while mucoepidermoid carcinoma was the most common malignant tumor (7.2%).
- The overall prevalence rate was 15.4 and the incidence rate was 2.51 per 100,000 persons, indicating that these tumors are relatively uncommon, primarily affecting the parotid gland.
Article Abstract
Background: To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile.
Material And Methods: Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records.
Results: The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000 persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%) and mucoepidermoid carcinoma was the most common malignant tumour (7.2%).
Conclusions: Salivary gland tumours are uncommon neoplasms that usually arise in the parotid gland. Pleomorphic adenoma and mucoepidermoid carcinoma were the most common benign and malignant tumours reported in this series.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is a rare type of primary salivary gland-type tumor of the lung. HCCC is characterized by unique pathological features, including nests, cords, or trabeculae of clear or eosinophilic tumor cells infiltrating a mucinous or hyalinized stroma. Additional analyses of this carcinoma have revealed positive epithelial markers via immunophenotyping and gene translocation through genetic testing.

Introduction: Thyroid lesions are one of the most common diseases observed in clinical practice in the North India. These diseases have distinct cytological morphology and thus FNAC is done frequently. Here we report a case of adenomatoid goitre mimicking adenoid cystic carcinoma (ACC) of salivary gland on cytology.

This study aims to investigate the diagnostic values of fine needle aspiration cytology (FNAC) and frozen section (FS) in evaluating parotid gland masses subjected to parotidectomy. A retrospective analysis of data from 274 patients who underwent parotidectomy for parotid gland masses was performed at the Department of Otolaryngology of the University Hospital between 2013 and 2019. We compared the preoperative FNAC and intraoperative FS records with the definitive histopathological diagnoses obtained from the surgical resection specimens.

Sjögren's syndrome (SS) is a chronic autoimmune disorder primarily affecting exocrine glands, leading to symptoms such as dry mouth and dry eyes. While SS can occur as a primary condition, it may overlap with other autoimmune diseases, complicating management. Autoimmune hepatitis (AIH), a liver disorder characterized by elevated serum globulins and liver-specific autoantibodies, can co-occur with SS, although this overlap is rare.

Pleomorphic adenoma (PA) is the most common benign histological form of salivary gland tumors, particularly in the parotid gland, primarily affecting women between the ages of 40 and 60. However, its occurrence in the trachea is very rare. This article reports the case of a 48-year-old woman presenting with progressive dyspnea and weight loss, initially suspected of having a pulmonary embolism.
