Background and Objective: Salivary gland tumors are an important part of oral pathology. The role of these cells in tumorigenesis has been reported but enough investigations have not been conducted about the role of mast cells in salivary gland tumors. This research aimed to study mast cells density in the most prevalent salivary gland tumors. Materials and Methods: In this cross-sectional s...
Salivary gland neoplasms account for 0.5-2% of all tumors worldwide, and can display a remarkable range of morphological diversity between different tumor types. The aim of this retrospective study was to present the clinico-pathologic characteristics of salivary gland neoplasms in a tertiary referral hospital in northwest region of Nigeria. Clinical and histopathological records of patients wi...
Giant submandibular sialolith of remarkable size in the comma area of Wharton's duct: a case report.
s U d s l T ialolithiasis accounts for more than 50% of the saliary gland diseases, with an estimated 12 of 1,000 ersons in the adult population being affected every ear. Most salivary calculi (80%-95%) occur in the ubmandibular gland, whereas 5% to 20% are found in he parotid gland. The sublingual gland and minor alivary glands are rarely (1%-2%) affected. Male paients are affected twice as mu...
conclusions a complete immunohistochemical study should be considered in cases of malignant salivary gland tumors. to reduce the recurrence rate of these tumors, the optimum therapies are radiotherapy and chemotherapy. introduction salivary gland tumors are rare head and neck lesions. the majority are benign, with only 20% of cases malignant. an epithelial-myoepithelial carcinoma is a rare low-...
salivary gland scintigraphy in patients with sjogren’s syndrome: a local experience with dual-tracer
objective(s): to review the findings of the patients with sjögren’s syndrome (ss) having technetium-99m-pertechnetate (99mtc-pertechnetate) and gallium-67 citrate (ga-67) salivary gland scintigraphy in the past eight years.methods: the patients with ss, who were referred to our department for salivary gland scintigraphy during january 2008-december 2015 were studied using both 99mtc-pertechneta...
INTRODUCTION Sialolithiasis is the most common disease of salivary glands. Sialography is particularly important for the assessment of the outflow tract and in diagnosing obstructive salivary gland lesions including calculi. CASE PRESENTATION We report on a 38-year-old female with sialolithiasis whom had Wharton's duct perforation, complicating the sialography. She was treated conservatively ...
background: superficial mucocele presents as small, clear vesicle on noninflamed mucosa. in this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele.case presentation: a 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. a mucosal biopsy was taken from the vesicle. ...
epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. here a case of 58-year-old female presented with left cheek swelling of one-year duration. ct scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. histological examin...
salivary gland tumors accounts for less than 1% of all tumors. minor salivary gland tumors (msgts) are uncommon and make up about 10% of all salivary gland neoplasms. the clinical and histopathological distribution of these tumors vary geographically. a case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. the tumor invaded into the anterior surf...
Sialolithiasis is one of the most common pathologies of the submandibular gland; sialoliths account for about 80 percent of all salivary duct calculi.The majority of sialolith occurs in the submandibular gland or its duct and is common cause of acute and chronic infection. Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, ...
