Nasal Angiofibroma; Ten Years’ Experience of Odd Criteria

Abstract

Introduction: Nasopharyngeal angiofibroma has usual characters regarding its origin, histopathology, vascular feeding and clinical presentation. In this study we have presented some cases of nasopharyngeal angiofibroma with unusual characters. Methods: A case series study that was conducted on patients with angiofibroma presented to otolaryngology department of Cairo University, between 2010 and 2020. Searching for unusual presentation. Results: Thirteen male patients with mean age 12.5 years had shown unusual character. Seven cases showed unusual vascular feeding pattern and six cases showed unusual character of anatomical location and extension (3 cases in whom the tumor is entirely medially located to sphenopalatine foramen and another 3 cases in whom the tumor is entirely laterally located to sphenopalatine foramen) Conclusion: Every day and other rhinologists all over the world report cases of nasopharyngeal angiofibroma. But some uncommon cases do not fulfill the typical epidemiological, pathological and clinical criteria and that is what was presented in this study. This study had highlighted 13 cases of angiofibroma with atypical characters regarding vascular feeding and locoregoinal extension.
