Primary cutaneous mucoepidermoid carcinoma (MEC) is a rare disease entity. Only around 20 cases have been reported so far. Herein, we present two cases for better understanding of the condition: A 74-year-old lady with a low-grade primary cutaneous MEC at her right external auditory ear canal was treated with surgical resection and adjuvant radiotherapy. The patient developed recurrence five mo...

IMPORTANCE Several recent US studies have documented racial disparities in head and neck cancer outcomes, but few have investigated racial and ethnic differences in salivary gland cancer (SGCA) survival. OBJECTIVE To determine whether patient race or ethnicity affects SGCA survival. DESIGN, SETTING, AND PARTICIPANTS Retrospective survival analysis of all patients with SGCA from 1988 through...

OBJECTIVES/HYPOTHESIS To determine clinical and pathological correlates of outcome among patients treated by surgery and postoperative radiation therapy for mucoepidermoid carcinoma of the parotid gland. STUDY DESIGN Retrospective review. METHODS The medical records of 61 patients treated by surgery and postoperative radiation therapy for localized mucoepidermoid carcinoma of the parotid gl...

Mucoepidermoid carcinoma (MEC) is a malignant neoplasms of the salivary glands which is rarely found in childhood. Its incidence rate has been reported to be 0.44 per 100,000.1 Most of them arise from the parotid gland (64 – 80%) while other locations that are less frequent include submandibular gland, sublingual gland, minor salivary glands and lacrimal gland.2 Submandibular gland cancer is ex...

OBJECTIVE To determine the presentation, pathologic features, treatment outcome, and prognosis of mucoepidermoid carcinoma of the parotid gland in children. DESIGN Retrospective clinical and histopathologic study with institutional review board approval. SETTING Tertiary pediatric medical center. PATIENTS Seven children (4 girls and 3 boys) presented with mucoepidermoid carcinoma of the p...

Central mucoepidermoid carcinomas (CMC) are uncommon tumours, comprising 2-3% of all mucoepidermoid carcinomas reported. They have been reported in patients of all ages, ranging from 1 to 78-years, with the overwhelming majority occurring in the 4th and 5th decades of life. They are histologically low-grade cancers, usually affecting the mandible as uniocular or multiocular radiographic lesions...

UNLABELLED Bronchial mucoepidermoid tumors are uncommon neoplasms, morphologically similar to their salivary gland counterpart. The histogenesis is controversial. The aim of this study is to identify myoepithelial cells and speculate on their role in the origin of these tumors. METHODS AND RESULTS Sixteen bronchial mucoepidermoid tumor surgical specimens were formalin-fixed, paraffin-embedded...

This review summarizes the new findings on salivary gland pathology under the following categories: immunohistochemistry; molecular genetics; newly recognized tumour types; known tumour entities with new findings; and progression of salivary gland tumours. In the application of immunohistochemistry, CD117 can aid in highlighting the luminal cell component of various salivary gland tumours, wher...

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 ...

A case report of mucoepidermoid carcinoma of the thymus, aggressively treated by multimodality therapy including surgery, radiotherapy, chemothermotherapy, and systemic chemotherapy is presented. The patient, a 53-year-old man, underwent potentially complete resection for an anterior mediastinal tumor, histologically diagnosed as a mucoepidermoid carcinoma of the thymus with Masaoka stage II di...
