Abstract:
Since the publication of the World Health Organization Classification of Head and Neck Tumors (Barnes et al., World Health Organization classification of tumours. Pathology and genetics head and neck tumours, IARC Press, Lyon, pp 10-80, 2001), a number of sinonasal lesions have been more completely described. This manuscript will focus on three such "new" lesions including sero mucinous hamartoma, HPV-related carcinoma with adenoid cystic-like features and low-grade sinonasal sarcoma with neural and myogenic features.
