Mucoepidermoid carcinoma of the bile duct is a rare entity. Only one mucoepidermoid carcinoma from the common bile duct has been reported in the Korean literature. Herein, we present the first in the English literature. The tumor arose in the intrapancreatic (distal) common bile duct in an 83-year-old woman who presented with obstructive jaundice and elevated liver enzymes. The tumor invaded th...

BACKGROUNDS Mucoepidermoid tumours arise from the ductal cells of the salivary glands, most commonly the parotid. The occurrence of these tumours in the mucus glands of the air passages is extremely rare. They are very aggressive tumours with poor prognosis. CASE A case of nasal mucoepidermoid carcinoma with probable origin from the middle turbinate is reported. CONCLUSION Nasal mucoepiderm...

BACKGROUND: Primary central mucoepidermoid carcinoma of jaws is a rare lesion comprising 2-3% of all mucoepidermoid carcinomas reported in literature. CASE PRESENTATION: The case presented here illustrates the hypothesis that its specific pathogenesis is unknown. CONCLUSIONS: Mucoepidermoid carcinoma of the jaw is a rare tumour of unknown aetiology. Although about a 100 cases has been reported ...

Background: Mucoepidermoid carcinoma ex-pleomorphic adenoma (MECxPA) is an extremely rare salivary gland malignancy. With only nine prior reported cases, this entity represents a challenging histopathological diagnosis. Methods: We present a case of a 71-year-old male with an enlarging left neck mass over several months. CT showed both a parapharyngeal space mass and a separate level II neck ma...

Abstract Introduction: Myofibroblasts are the main stromal components that constitute the desmoplastic reaction of host cells to inductive stimuli exerted by tumor cells. The purpose of this study was to evaluate the score of myofibroblasts using α -smooth muscle actin marker (α–SMA) in mucoepidermoid carcinoma (MEC) in comparison with pleomorphic adenoma (PA)and study the amount presence of t...

Mucoepidermoid carcinoma represents about 5% of all salivary gland tumors, in which, about one-third occurs in the minor salivary gland. Mucoepidermoid carcinoma is the third most frequently encountered minor salivary gland tumor, preceded only by a mixed tumor and adenoid cystic carcinoma. The affected minor salivary glands are most frequently located in the palate, followed by the lower lip. ...

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, ...

Mucoepidermoid carcinoma (MEC) is a malignant epithelial neoplasm composed of both mucus secreting cells and epidermoid-type cells. Mucoepidermoid carcinoma arising from mucous glands of maxillary sinus is extremely rare and accounts for 13% of all malignancies occurring in maxillary sinus. While the high-grade MEC is a highly aggressive tumor, its low-grade counterpart usually demonstrates a m...

Background: Parotid tumor is a supporter of saliva that occurs most often among the tumors present in other saliva. with slow progression rate, so it makes patients serve to seek treatment.Objective: This study aims determine characteristics parotid RSUP. Dr. M. Djamil Padang.Methods: type research descriptive retrospective approach. was conducted from March August 2020 at Medical Record Instal...

INTRODUCTION Patients with metastatic mucoepidermoid carcinoma of salivary glands have a poor outcome. The epidermal growth factor receptor protein is overexpressed in approximately 70% of mucoepidermoid carcinoma patients and may represent a therapeutic target. However, whether treatment with anti-epidermal growth factor receptor agents is effective is unclear and clinical trials are difficult...
