GIANT EPITHELIAL MYOEPITHELIAL CARCINOMA OF PAROTID GLAND- A CASE REPORT
Abstract
Epithelial myoepithelial carcinoma is a rare
salivary gland tumor consisting of inner
duct lining epithelial cells and outer clear
myoepithelial cells, which is characteristic
composition of biphasic tubular structure. It
was first described by Donath et al in 1972
and classified as a rare low grade biphasic
neoplasm of salivary glands.In 1991, WHO
recognized this tumor as a distinct entity
and subtype of salivary gland adenocarcinoma
which became a part of new classification
system.Morphological features and
immunohistochemistry distinguish the two
cell types of this tumor. This is a case report
of epithelial myoepithelial carcinoma
of parotid gland in a 46 year old male patient.
