squamous cell carcinoma comprises 95% of laryngeal carcinomas. it is usually detected by laryngoscopic evaluation. imaging plays an important role in the evaluation of submucosal extension and staging of this malignancy. supraglottic, glottic and sublottic regions are separately evaluated. in supraglottic region extension of the mass to preepilottic and paraglottic spaces and cartilges invasion...

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...

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...

objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...

Tuberculosis (TB) accounts for the highest number of mortalities among infectious diseases worldwide. Laryngeal TB is an extremely rare presentation of TB. It has many similarities to laryngeal carcinoma, one of the three most common cancers among males in the city, with an age standardized rate of 8.6. The associated risk factors of laryngeal carcinoma i.e. smoking, paan, betel nut usage and a...

A small sub-population of cells characterized by increased tumorigenic potential, ability to self-renew and to differentiate into cells that make up the tumor bulk, has been characterized in some (but not all) tumor types. These unique cells, namedcancer stem cells, are considered drivers of tumor progression in these tumors. The purpose of this work is to understand if cancer stem cells play a...
