introduction: salivary gland tumors (sgts) are important parts of human neoplasms. the most common sgt is pleomorphic adenoma and the most common malignant sgts are mucoepidermoid carcinoma and adenoid cystic carcinoma (acc). metastasis-associated genes 1 (mta1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

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-...

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...

human herpes virus 8 (hhv8) causes kaposi’s sarcoma, a common cancer among aids patients. it is proposed that this virus plays a role in formation of some blood vessel and lymphoma tumors. this study aimed to investigate the frequency of kshv among benign and malignant breast tumors. a total of 24 carcinomas and 24 fibroadenomas paraffin embedded tumoral tissue samples were obtained from the pa...

Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

Background: The higher frequency of malignant skin tumors is of great significance in renal transplant recipients (RTRs) who should receive immunosuppressive therapy for a long time. This study was designed to determine the frequency of malignant skin tumors in RTRs in Imam Reza Hospital, Mashhad, Iran, in 2001-2002.Method: This descriptive study was performed on 322 recipients who were examine...

Introduction: Natural killer (NK) cells, of which CD56 is a specific marker, play an important role in host defense against tumors. Cancer stem cells, of which aldehyde dehydrogenase isoform 1 (ALDH1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. We aimed to evaluate the expression of ALDH1 and CD56 in common salivary g...
