abstract salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. most benign tumors occur in the parotid gland. pleomorphic adenoma is the most common type. basal cell adenoma is a subtype of the monomorphic adenoma with rare occurrence. proper diagnosis and clinical evaluation by the use of radiography can lead the physician to t...
by increasing number of vessels. salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. salivary gland hemangioma makes up 1 % of all salivary gland tumors. trismus resulting from parotid hemangioma is so rare. the patient was a 6-month-old boy with a huge lesion in his right parotid who referred to shahid sadoughi hospital of yazd, iran. the lesion appea...
background and aims. although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. this study aimed to evaluate the efficacy of magnetic resonance imaging (mri) and color doppler ultrasonography parameters in the diagnosis and differenti...
The expression of sex hormone receptors in some tumors suggests a role for these receptors in tumor pathogenesis and therapy. Previous studies of the expression of estrogen and progesterone receptors in salivary gland tumors have reported conflicting results. We evaluated the immunohistochemical expression of androgen, estrogen, and progesterone receptors (AR, ER, and PR) in a series of 78 form...
Salivary gland tumors are often considered difficult to diagnose pathologically because of their histological variability and complexity. There were only nine types in the first edition (1972) WHO classification salivary tumors; however, 35 will be adopted 5th (2022). This is mainly due epidemiological data, recognition new concepts, advances immunohistochemistry discovery tumor-specific gene m...
Salivary gland tumors are rare and account for 2-3% of tumors occurring in the head and neck. Pleomorphic adenoma is a benign neoplasm which is commonly encountered in the parotid gland and other major salivary glands. At times they can also develop in minor salivary glands of the palate. The majority of minor salivary gland tumors are malignant. This case report describes a case of mixed tumor...
OBJECTIVE To detect immunohistochemically the N-cadherin expression in different types of benign and malignant salivary gland tumors in an attempt to note any possible correlation to their development, stage and invasive properties. MATERIALS AND METHODS N-cadherin expression was examined in tissue specimens from 49 salivary gland tumors including: pleomorphic adenomas (4), Warthin's tumors (...
introdouction: mucoepidermoid carcinoma (mec) is one of the most common salivary gland malignancies. the prevalence of salivary gland tumors varies in different geographic areas. in this report, we evaluated the prevalence of mec in iran and compared it with that previously reported in other countries. materials and methods: the files of oral pathology, shahid beheshti university of medical sci...
BACKGROUND Dysgenetic polycystic salivary gland disease is a rare pathology. No case of minor salivary gland involvement has been reported in the literature. METHODS A female patient presented with bilateral tumors of the parotid glands, bilateral submandibular gland enlargement, and multiple cystic lesions of the oral mucosa. MRI of the neck was performed along with fine-needle aspiration (F...
Salivary gland tumors are uncommon within children and when they do arise, they mainly affect the major salivary glands. Minor salivary gland tumors are rare in children, which are responsible for less than 10% of all the cases. Pleomorphic adenoma is the most common tumor of the sa...
