The paper characterizes sclerosing mucoepidermoid carcinoma with eosinophilia, a rare thyroid tumor, including histological and immunohistochemical features. The authors give their observation of a 26-year-old patient. The immunohistochemical findings (positive p63 and TTF-1 tumor cell nuclear staining) show the dual nature of a tumor arising from the cells of the ultimobranchial body and folli...

Tumors of salivary glands are uncommon and comprise of about 2%-4% of all head and neck tumors. About 75%-80% of these tumors are benign and include pleomorphic adenoma, monomorphic adenoma, oncocytoma, and papillary cystadenoma lymphomatosum. Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands, representing 5-10% of all salivary gland tumors. Although known to be met...

In this issue of Clinical Cancer Research , Okabe et al. (1) have analyzed 71 cases of mucoepidermoid cancer and 51 cases of non-mucoepidermoid cancer for the presence of the Mect1Maml2 fusion oncogene and have made a valuable observation. They confirmed that Mect1-Maml2 expression is specific for mucoepidermoid cancer and showed that fusion-positive tumors have histologic and prognostic featur...

twenty five cases of minor saliva ry glands tumors which was observedat the department of pathology of university of tehran from 1967 to 1972 are presented and discussed . benign mixed tumor is the most common and the only benign lesion in this series of 75 patient with intraoral salivary gland tumor. there were eleven malignant type and hence about 44% of all the tumor arc malignant and it cor...

The authors report the case to understand this unusual presentation and prognosis of mucoepidermoid carcinoma following treatment. We present a case of mucoepidermoid carcinoma in a 67-year-old man. The cancer was diagnosed in the right side of his neck but the primary tumor remained unknown despite attempts at staging. The neck was treated successfully and followed up for 2 years. Metastasis o...

introduction the application of immunohistochemical method has resulted in marked improvement of the microscopic diagnosis of neoplasms combined with h&e; staining. although unique cellular antigens have not been found in salivary gland neoplasms, multiple less specific immunomarkers have been used and may be helpful in elucidating the role of myoepithelial differentiation in those neoplasms. t...

UNLABELLED As rare condition, mucoepidermoid carcinoma may occur in liver although its etiology and pathogenesis is still unclear. We report here a case of intrahepatic mucoepidermoid carcinoma misdiagnosed as cholangiocarcinoma and squamous cell carcinoma by preoperative radiologic and intraoperative histological examinations, respectively. A 60-year-old woman presented with a 1-month history ...

INTRODUCTION Mucoepidermoid carcinoma of the tracheobronchial tree is rare. Such tumors usually present with signs and symptoms of bronchial obstruction. Histologically, they can be classified as high-grade or low-grade tumors. Experience of imaging these tumors with 18fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) is limited. We present three cases of this...

The biological features and the clinical behavior of the mucoepidermoid carcinoma are varied and not known yet. The aim of present paper was to analyze the potential prognostic factors affecting the survival of patients diagnosed with primary mucoepidermoid carcinoma of head and neck. A retrospective study was conducted in 16 patients treated between 1990 and 2008 in the General Hospital of Rib...
