Objective: this was a retrospective descriptive study aimed to assess the role of latent membrane protein-1 (LMP-1) Monoclonal Antibody in the detection of Epstein- Barr virus (EBV) in nasopharyngeal carcinoma (NPC) lesions in Sudanese patients. Methods: Forty-five paraffin-embedded formalin-fixed tissue sections of nasopharyngeal carcinoma lesions were stained by Anti- EBV LMP-1 and results were correlated with the available clinical data. Results: EBV was positive in 23 cases and negative in 22 cases. Most positive results were in elderly males with undifferentiated carcinomas. Conclusion: Anti- EBV LMP-1 is effective in detecting EBV in nasopharyngeal carcinoma lesions.
