introdouction: mucoepidermoid carcinoma (mec) is one of the most common salivary gland malignancies. the prevalence of salivary gland tumors varies in different geographic areas. in this report, we evaluated the prevalence of mec in iran and compared it with that previously reported in other countries. materials and methods: the files of oral pathology, shahid beheshti university of medical sci...

PURPOSE Mucoepidermoid carcinoma is the most common primary malignancy of the salivary gland. Mucoepidermoid carcinoma translocated gene 1-mastermind-like gene family (MECT1-MAML2) gene fusion was identified from a recurring t(11;19)(q21;p13) translocation, which is often the sole cytogenetic alteration in this disease. This fusion transcript has been frequently detected in mucoepidermoid carci...

Mucoepidermoid carcinoma is the most common malignant salivary gland tumour. However, short series or individual case reports have identified this tumour in the maxilla, mandible, breast tissue and thymus. Mucoepidermoid carcinoma originates from minor salivary glands, and it is therefore surprising that it is not more commonly seen in the tonsil. To date, we believe there has been only one pre...

BACKGROUND AND OBJECTIVE Primary mucoepidermoid carcinoma of the jaw is a rare lesion, comprising 2-3% of all mucoepidermoid carcinomas reported in literature. Central mucoepidermoid carcinoma of the maxilla is rarer, comprising only 8% of the mucoepidermoid carcinomas found in the jaw. METHODOLOGY A 52-year-old man suffered from central mucoepidermoid carcinoma of the right maxilla with cerv...

introduction: cigarette smoking and alcohol consumption have a well-known effect on the development of upper aerodigestive tract carcinomas, but such a role for opium is questionable. this study was designed to assess the correlation between opium inhalation and cancer of the larynx and upper esophagus. materials and methods: fifty eight patients with laryngeal cancer, ninety eight patients wit...

As one of the most common malignancies of the salivary glands, mucoepidermoid carcinoma had a rare frequency in mandible. A case of central mucoepidermoid carcinoma of the mandible was reported and relevant literatures were reviewed. The possible etiology, clinical symptom, radiology, histopathology, diagnosis and treatment of central mucoepidermoid carcinoma were discussed.

Mucoepidermoid carcinoma (MEC) is one of the most common histological malignant salivary gland tumors, it frequently diagnosed in parotid gland. MEC also intra oral minor glands. Only a few cases tonsillar have been reported. We present rare case mucoepidermoid arising from left pharyngeal tonsil. This report shows that important to perform tonsillectomy when discovering neck metastasis tumors ...

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...

conclusions regarding the findings of this study, it can be concluded that erα possibly cannot play an important role in the tumorigenesis and prognosis of the investigated malignant salivary gland tumors. results for acc, only one specimen expressed the er, and this was assessed as moderate. no specimens of mec expressed the er. the comparison of er expression between the two groups was not me...
