Objectives: Signet Ring Cells (SRCs) are often seen in gastrointestinal, breast, bile duct and lung invasive carcinomas. Observing these cells in benign and malignant lesions of the salivary glands is not common. Signet-ring cell adenocarcinoma is rare and is commonly seen in the secondary salivary glands. Although, the presence of SRCs in other neoplasms of the body is usually associated with ...
introduction: sialadenoma papilliferum (sp) is a rare benign tumor, which originates from the minor salivary gland. it occurs at sites that have minor salivary glands, such as the palate, retromolar pads, buccal mucosa, and lips. the most common location for tumor development is on the hard palate. a differential diagnosis consists of ruling out other salivary gland tumors. transoral robotic su...
BACKGROUND Minor salivary gland tumors of the sinonasal region are rare. Minor salivary gland tumors of this region behave differently from other subsites in the head and neck. The objective of our study was to analyze the survival and prognostic factors in patients with minor salivary gland tumors of the sinonasal region. METHODS We carried out a retrospective review of patients with minor s...
INTRODUCTION Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors. MATERIALS AND METHODS In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with m...
Basal cell adenoma (BCA) of the salivary glands is a rare benign tumor resembling pleomorphic adenoma, but with a prominent basaloid cell layer. The majority of these tumors arise in the parotid glands and account for only 1% of all salivary gland epithelial tumors. We report one such case of a swelling in the floor of the mouth in a 55-year-old female where BCA is the most likely diagnosis; ho...
M ammary analogue secretory carcinoma is a primary salivary gland tumor that was first described in 2010, with histologic, immunophenotypic, and genetic features reminiscent of secretory carcinoma of the breast. Both tumors harbor the same defining ETV6eNTRK3 fusion gene, resulting from the t(12;15) (p13;q25) translocation. Of interest to dermatopathologists, primary cutaneous tumors resembling...
Background: Salivary gland tumors are rare head and neck tumors with lymphoepithelial carcinoma (LEC) as a particularly infrequent variant. This study was an evaluation of the incidence of EBV infection in malignant salivary gland tumors with the emphasis on tumor type and geographical area. Methods: Five databases (PubMed, ScienceDirect, Scopus, Web of Science and Cochrane library) were search...
Introduction salivary gland tumors are relatively rare and constitute 3-4% of all head and neck neoplasms. The majority (70%) of salivary gland tumors arise in the parotid gland. Recommended treatment for a parotid mass is surgical excision with a surrounding cuff of normal tissue to prevent recurrence. Nematollah Mokhtari Amir Majdi. MD Professor of otorhinolaryngology, Membership of ear, nose...
Background: Salivary gland tumors are relatively uncommon. It accounts for < 2% of all human neoplasms. They pose considerable clinical management challenges because of their confounding histological and behavioral diversity as well as their proximity to important head and neck structures. The present study was conducted to account different salivary gland tumors among different population. Mat...
Warthin’s tumor, cystadenolymphoma, papillary cytoadenoma lymphomatomsum and adenolymphoma are all different terminology of the same pathology. Warthin’s tumor is a benign salivary gland tumor arises almost exclusively in intraor periparotid lymphoid stroma and represents 5-8% of all salivary gland tumors. It accounts for 8-12% of all benign tumors affecting the parotid gland, and ranks as the ...
