Introduction: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. Case Report: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, ...

BACKGROUND Radiation-induced salivary gland tumors are well described in the literature, with mucoepidermoid cancer being the most common histologic entity. Epithelial-myoepithelial carcinoma is a rare tumor accounting for <1% of all tumors in the salivary glands. METHODS AND RESULTS We describe the first case of radiation-induced epithelial-myoepithelial carcinoma in the English-language med...

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...

BACKGROUND The incidence of salivary gland tumors is claimed to be influenced by geographical and racial factors. The pathological classification and nomenclature of salivary gland tumors as defined by WHO classification (1991), is accepted world-wide but little is available in the literature regarding the spectrum of salivary gland tumors in Africa in the basis of this classification. Such eff...

Salivary gland cancers comprise a small subset of human malignancies, and are classified into multiple subtypes that exhibit diverse histology, molecular biology and clinical presentation. Local disease is potentially curable with surgery, which may be combined with adjuvant radiotherapy. However, metastatic or unresectable tumors rarely respond to chemotherapy and carry a poorer prognosis. Rec...

Salivary gland neoplasms are a rare group of tumors; the annual incidence rate is 1 in 100,000 individual, comprising about 3% of all head and neck neoplasms [4]. The mean age of patients with salivary gland tumors is 45 years, peaking in the sixth and seventh decades of life. Benign salivary gland tumors occur more frequently in females, while malignant tumors are slightly more frequent in mal...

Mucoepidermoid carcinoma (MEC) is the most&#x0D; common malignant tumor of salivary gland and&#x0D; most commonly seen in parotid. Oncocytic&#x0D; mucoepidermoid (OMEC) a rare&#x0D; subtype. Here, we aimed to present histological,&#x0D; immunohistochemical, and molecular results a&#x0D; 28-year-old female patient followed for endometrial&#x0D; cancer, whether mass right parotid primary or metas...
