BACKGROUND The differential diagnosis of salivary carcinomas is always difficult and challenging. Salivary neoplasms often shows more than one growth pattern and significant morphologic variability may exist within a single tumor and between different tumors. The aim of this study was to examine the role of DOG1 (discovered on gastrointestinal tumor-1) and p63 immunohistochemistry in the diagno...

Primary bronchial mucoepidermoid carcinoma in the lung is relatively rare. It rarely presents with the highly malignant biological characteristic of bone marrow metastasis. We describe a case of this disease with bone marrow metastasis. A 56-year-old man with the primary manifestation of bone pain and bloodstained sputum had two abnormal shadows on the left inferior lobar bronchus and periphera...

The authors investigated the association between cellular phone use and epithelial parotid gland malignancy. The subjects were 136 cases who were treated for this condition at the authors' hospital from January 1993 to March 2010, and 2051 controls who did not have salivary gland tumours and were admitted to the oral and maxillofacial surgery department during the same period. Logistic analysis...

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...

BACKGROUND Pulmonary mucoepidermoid carcinoma (PMEC) is a rare malignant neoplasm with remarkable resemblance to mucoepidermoid carcinoma of the salivary glands. It constitutes a unique set of patient population. In this study we briefly discussed the current state of knowledge of PMEC and described the clinical presentation and management of 27 PMEC cases. This study aimed to discuss the utili...

mucoepidermoid carcinoma of the pancreas is rare. here, a 63-year-old woman with left upper abdominal pain and abdominal distension is presented. her mucoepidermoid carcinoma was located at the left upper abdomen, arising from the pancreatic body and tail without invasion of pancreatic capsule. on pathologic examination, the tumor consisted of three types of cells, the majority being poorly dif...

This study aimed to evaluate the clinical outcomes of patients with mucoepidermoid carcinomas in the head and neck treated with carbon-ion radiotherapy. Data from 26 patients who underwent carbon-ion radiotherapy in four facilities were analyzed in this multi-institutional retrospective study: the Japan Carbon-ion Radiation Oncology Study Group. The median follow-up time was 34 months. One pati...

Primary mucoepidermoid tumors of the lung are rare entities. Synchronous primary malignancies of the lung involving mucoepidermoid carcinoma and mucinous adenocarcinoma are even rarer and constitute a unique set of patient population. The presentation, diagnosis and treatment strategies for this patient population are not well described. In most cases, the diagnosis of synchronous primary lung ...

INTRODUCTION Bronchogenic cysts may rupture or become infected, and malignant degeneration may occur. Although various types of malignant degeneration have been described, only a few reports of mucoepidermoid carcinoma arising from a bronchogenic cyst have been published. We report such a case. CASE A 77-year-old female was referred to our institution for evaluation of left chest pain. A comp...
