MUCO EPIDERMOID CARCINOMA OF THE PAROTID - AN INTERESTING CASE REPORT
Abstract
Mucoepidermoid carcinoma as an entity
was first described by Stewart in 1945.
He considered this tumor to arise from
the pluri-potent reserve cells of salivary
gland ducts. These reserve cells have
the potential to develop into squamous,
columnar and mucoid cells. This tumor
constitutes about 5 of all malignant salivary
gland tumors. It is more common in
the parotid gland. Usually these tumors
are asymptomatic, but may cause pain
when they become aggressive. These
tumors usually do not involve the facial
nerve and commonly is confined to the
superficial lobe of parotid gland.This tumor
commonly arises in middle aged and
young adults and is rare in elderly. This
case is being reported because it is a
rarity in this age group and duration. Mucoepidermoid
carcinoma may become
cystic because of the presence of
mucoid cells which secrete mucous.
There are two malignant lesions that are
known to cause cystic lesions in the
parotid gland. They are mucoepidermoid
carcinoma and adenocystic carcinoma.
