CONTEXT Among the cytological and morphological properties of mucoepidermoid carcinoma, one of the most important criteria for measuring its biological behavior and aggressiveness is cell proliferation. In this way, immunohistochemical markers of cell proliferation have been found to be useful in tumor classification and have formed part of the prognostic and therapeutic studies of these pathol...

Objective: To investigate the clinicopathological, therapeutic, and survival data on pediatric major salivary gland cancers. Materials Methods: National Cancer Database (NCDB) query from 2004 to 2018. Results: In total, 967 cases of individuals under age 21 were identified. Most cancers affected parotid (86%). Mucoepidermoid carcinoma (41.3%) acinic cell adenocarcinoma (33.6%) most common. Tumo...

The 22 adenosquamous carcinoma cases were studied clinicopathologically. The tumor provides many difficulties such as: rapid spreading properties, delayed detection as advanced carcinoma because of the presence of endophytic growth, frequent prevalence of vessel permeation, and radioresistance. Adenosquamous carcinoma was categorized histochemically and histomorphologically into two types--aden...

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...

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...

Central mucoepidermoid carcinoma (CMC) of the jaw bones is a rare malignant salivary gland tumor of unknown pathogenesis, comprising about 4% of all mucoepidermoid carcinomas (MECs). Most cases are histologically classified as a low-grade tumor and radiographically appear as a well-defined unilocular or multilocular radiolucent lesion. Block resection or wide local excisions are the treatment o...

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...

Introduction: Salivary gland cancers impose a huge part in oral and maxillofacial pathologies. Mucoepidermoid (MEC) adenoid cystic carcinomas (ACC) are salivary malignancies, where being the most common cancer. CD44, is family of transmembrane non-kinase cell surface glycoproteins, that was broadly used as marker for cancer stem cells (CSCs) various malignancies. CD44 found to be overexpressed ...

introdouction: mucoepidermoid carcinoma (mec) is one of the most common salivary gland malignancies. the prevalence of salivary gland tumors varies in different geographic areas. in this report, we evaluated the prevalence of mec in iran and compared it with that previously reported in other countries. materials and methods: the files of oral pathology, shahid beheshti university of medical sci...
