a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...

OBJECTIVES To determine the expression level of the Wnt components-WIF1 (Wnt inhibitory factor 1), WNT1, and beta-catenin-in salivary gland tumor cells and to investigate the mechanisms that contribute to activation of the Wnt pathway in human salivary gland tumors. DESIGN The expression of WIF1, WNT1, and beta-catenin in salivary gland normal tissue and tumor cell lines was analyzed by rever...

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...

background: salivary gland tumors are among malignancies that have high recurrence rate. immune responses in salivary gland tumors have not been well elucidated. t helper type 1 (th1) and th2 cytokines have been reported to play a role in the outcome of head and neck cancers. objective: to evaluate the serum levels of interferon gamma (ifn- γ), as the hallmark of th1 cytokines, and interleukin-...

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...

background and aims. salivary gland tumors are rare and specific lesions. there are differences in the incidence and frequency of salivary tumors in both minor and major salivary glands in different countries. this study was carried out to determine the prevalence of major and minor salivary gland tumors in ahvaz in the south of iran. materials and methods. all the cases, recorded in imam khome...

ABSTRACT Introduction: Pleomorphic adenoma is the most common tumor of the salivary gland. The tumor most commonly arises in the parotid or submandibular salivary glands. Infrequently, it arises from minor salivary glands. Minor salivary gland tumors are mostly malignant. Case Report: We report four cases of pleomorphic adenoma of hard palate. All four cases range from 30–45 years. All were ben...

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...

Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...

background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...
