Overview
Classification
Nasopharyngeal carcinoma is classified as a malignant neoplasm, or cancer, arising from the mucosal epithelium of the nasopharynx, most often within the lateral nasopharyngeal recess or fossa of Rosenmüller. There are three microscopic subtypes of NPC: a well-differentiated keratinizing type, a moderately-differentiated nonkeratinizing type, and an undifferentiated type, which typically contains large numbers of non-cancerous lymphocytes (chronic inflammatory cells), thus giving rise to the name lymphoepithelioma. The undifferentiated form is most common, and is most strongly associated with Epstein-Barr virus infection of the cancerous cells.[1]
