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...

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. ...

BACKGROUND Lacrimal sac tumors are very rare and are often missed because patients present with features consistent with chronic dacryocystitis. Squamous cell carcinoma is the common-est lacrimal sac malignancy. Although primary mucoepidermoid carcinomas of the lacrimal sac are rare, they are locally aggressive. Furthermore, their proximity to vital structures and the skull base makes them pote...

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...

The biologic behavior and factors influencing the development of salivary gland mucoepidermoid carcinoma are not fully understood. Alteration of the cyclin-dependant kinase inhibitor p21(WAF) could cause uncontrolled proliferation leading to cancer. Thirty-five mucoepidermoid carcinomas were graded and immunohistochemically stained for p21(WAF). The percentage of positive tumor cells was determ...

Mucoepidermoid carcinoma of the tracheobronchial tree is a rare airway tumor (<1% of all lung tumors). In adults, the majority of primary tracheal tumors are malignant. Management during pregnancy is complex and requires weighing maternal and fetal prognosis. Reported cases describe surgical resection following cesarean section. We report the first case to be treated by Argon-Plasma Coagulation...

UNLABELLED Mucoepidermoid carcinoma is a common malignant epithelial tumor of salivary glands, but relatively rare in lung. The histological features of mucoepidermoid carcinoma of the lung are similar to its counterpart arising from the salivary glands. Here, we reported a special tumor that occurred in the medial segment of the right lower lobe in a 22-year-old man. This tumor exhibited typic...

There are few reliable prognostic markers of biological aggressiveness for head and neck carcinomas in general. For salivary gland carcinomas, anatomic location, tumor size, histological grade, and extent of disease involvement are considered to be clinically important risk factors for recurrent disease. Molecular genetic alterations in salivary gland carcinomas have not been characterized, and...
