Diagnosis of Nasopharyngeal Carcinoma by DNA Amplification of Tissue Obtained by Fine-Needle Aspiration

Abstract
In nasopharyngeal carcinoma the primary lesion is often difficult to find. Metastatic lesions occur frequently but are difficult to distinguish from other head and neck tumors. The viral genome of the Epstein-Barr virus (EBV) can be identified in the cells of this carcinoma.
