آملوبلاستومای تک کیستی: بررسی کلینیکو پاتولوژیک 52 مورد

Introduction: Unicystic ameloblastoma is a subtype of ameloblastoma with some differences in clinical behavior such as lesser recurrence rate and aggressiveness. This lesion has 3 types: luminal, intraluminal and mural. The diagnosis of unicystic ameloblastoma is based on histopathology and radiological characteristics. Objective: This study attempts to determine the prevalence of unicystic ameloblastoma and its relationship with age, gender and the location of unicystic ameloblastoma subtypes. Material & Methods: This retrospective and case series study was performed in oral and maxillofacial pathology in pathology department of dentistry faculty of Tehran University of Medical Sciences in which medical records of the patients were assessed from 1967 to 2004.
