Acinic cell carcinoma is an uncommon low-grade malignant tumor of salivary glands. It was first described by Nasse in 1892, arising in parotid salivary gland. Salivary gland tumors are also known to develop within jaw bones, arising within the jaw as a primary central lesion, and are extremely rare with only a few cases reported. We present a rare case report of 65-year-old woman with intraosse...
introduction: the use of radioactive iodine (131i) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. salivary gland has the ability to concentrate radioactive iodine under normal circumstances. salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. the purposeof this study was to determine the absorbed dose of...
introduction: malignant salivary gland tumors are rare entities. despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. the activation of egfr- ras-raf signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
ABSTRACT Introduction: Salivary gland tumors are rare malignant neoplasms, with a higher incidence in the parotid gland. Despite their low incidence, possible complications derived from them can lead to high comorbidity patients. Methods: We conducted retrospective, observational and descriptive study of 105 patients diagnosed neoplasms salivary glands at Hospital Universitario La Paz. 102 corr...
Polymorphous adenocarcinoma is a slow growing malignant tumor of minor salivary glands. The most common location these tumors palate, buccal mucosa, upper lip, floor mouth and retromolar region. This neoplasm characterized by cytological uniformity, architectural diversity infiltrative growth pattern. case report polymorphous occurring in lacrimal gland. They are seldom reported this propose un...
INTRODUCTION Minor salivary gland neoplasms of epithelial origin are rare in children and adolescents and most are not well documented, except for a few small series and case reports. This study represents a retrospective clinical analysis of nine cases of benign epithelial salivary gland neoplasms accessioned over a 35-year period at the Louisiana State University School of Dentistry and combi...
Nasal and upper respiratory tract obstruction in the neonatal period can result from a variety of conditions, and may be present with variable symptoms. Salivary gland anlage tumor, also referred as congenital pleomorphic adenoma, is a very rare benign congenital tumor of the nasopharynx, which may produce nasal obstruction and other associated, nonspecific symptoms. We report a case of congeni...
OBJECTIVES PD-1/PD-L1 and CTLA-4 have been investigated and are thought to play an important role in tumor evasion. This study aimed to investigate expression patterns of immune-related molecules, and their clinical impacts in malignant salivary gland tumors. PATIENTS AND METHODS We performed immunohistochemical staining for PD-L1, PD-L2, CTLA-4, PD-1, and CD8+ tumor-infiltrating lymphocytes ...
Lymphoma of the salivary gland accounts for 5% of cases of extranodal lymphoma and 10% of malignant salivary gland tumors. Most primary salivary gland lymphomas are B marginal zone lymphomas arising on a background of sialadenitis associated with an autoimmune disorder such as Sjorgen's syndrome. This report describes a case of primary B-cell lymphoma arising in the parotid gland in a middle-ag...
Salivary gland neoplasms are remarkable for their histological diversity and several studies point to their varied occurrence in the population. Clinical aspects were histologically assessed to determine possible associations and define parameters to differentiate benign and malignant neoplasms. The case files of patients diagnosed with epithelial salivary gland tumors between 1989 and 2005 wer...
