Sun Yat-sen University Cancer Center is a well known in-stitution for diagnosis， treatment and research work on na-sopharyngeal carcinomas （NPC）. The affiliated hospital hasadmitted and treated thousands of patients coming from all overthe country and the southeastern Asia. In order to providingmore facilities and references in contributing to training ofmedical professionals and to raise further the diagnosis and re-search level of NPC， the authors compiled this atlas by collect-ing photographs with either gross or microscopic findings from211 248 biopsies and 8，848 autopsies. Among them， a few cas-es are from Sun Yat-sen College of Medical Sciences. We hopeit will enrich further the documents of pathology， oncology andotorhino laryngology.
