20 de jun. de 2024 · Acinic cell carcinoma is a malignant epithelial neoplasm of the salivary glands characterized by serous acinar cell differentiation (cytoplasmic zymogen granules) in at least some of the neoplastic cells.
23 de jun. de 2024 · The general anatomy and histology of human major and minor salivary glands are described. The sublingual glands and all minor glands develop in the submucosa close to the sites of the oral mucosa where the openings of their excretory ducts are located.
27 de jun. de 2024 · Histologically, tumors consisted of rounded to angulated ductal cysts lined by epithelial cells with abundant finely granular eosinophilic cytoplasm and large nuclei with prominent nucleoli. Pleomorphism was mild to moderate, the mitotic rate was low, and necrosis was absent.
Hace 1 día · Although rare overall, salivary gland carcinomas (SGCs) are among the most common oral and maxillofacial malignancies. The aim of this study was to develop a machine learning-based model to predict the survival of patients with SGC. Patients in whom SGC was confirmed by histological testing and who underwent primary extirpation at the authors’ institution between 1963 and 2014 were identified.
23 de jun. de 2024 · Salivary tissue is distributed throughout the aerodigestive tract, and the bulk of salivary mass is found within the major salivary glands. The parotid is the largest salivary gland by volume, and the “Rule of 80’s” is often quoted when discussing parotid tumors.
Hace 1 día · The relationship between SG obstruction, inflammation, and functional consequences is complex. Inflammation in the salivary ducts causes thickening of the ductal epithelium, leading to impaired salivary excretion. The inflammatory response also induces acino-ductal metaplasia, reducing the quantity of saliva and altering its composition .
12 de jun. de 2024 · Histology plays a critical role in the definitive diagnosis, and confirming the primary origin of lymphoepithelial carcinoma after ruling out metastasis from undifferentiated nasopharyngeal carcinoma. The mainstay of treatment is a combination of surgical resection and adjuvant radiotherapy.
