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 the best t...
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...
Patients with salivary gland disease most frequently present with complaints of oral dryness, swelling, or a mass in a gland. This chapter first reviews briefly the anatomy and physiology of the salivary glands and then outlines a diagnostic approach to the patient who has signs and symptoms that are suggestive of salivary gland dysfunction. The examination of a patient with dry mouth is descri...
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...
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...
Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
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...
BACKGROUND Salivary gland dysfunction with xerostomia is a major clinical problem without a causal therapy in most cases. The development of an animal model for scintigraphic assessment of salivary gland function has great clinical relevance for the investigation of promising new diagnostic and therapeutic strategies for chronic salivary gland diseases. This study reports the first experiences ...
Sjögren’s syndrome (SS) is an autoimmune disease in which exocrine glands including the salivary gland are targeted and destroyed by the immune system (Voulgarelis and Tzioufas, 2010). SS and the side-effects of γ-radiation therapies for head and neck cancers cause salivary gland dysfunction, in particular hyposalivation (Atkinson et al., 2005; Fox, 1998; O'Sullivan and Higginson, 2010). Among ...
