Ameloblastoma is the most common epithelial odontogenic tumor. It may show locally invasive behavior resulting in recurrence and malignancy. Therefore, appropriate diagnosis of this tumor is necessary. The aim of this study was to evaluate clinicopathological characteristics of ameloblastomas in an Iranian population. We present a 40-year retrospective study of patients diagnosed from 1971 to 2010 in the Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, Mashhad, Iran. Information gathered from patient records included age, gender, tumor location and histologic type. The frequency of odontogenic tumors among all lesions was 2.08% and ameloblastoma with 88 samples demonstrated the greatest prevalence (41.5%). Regarding gender, 60% of samples occurred in males. The mean age of studied patients was $33.02{\pm} 15.74years$ with a peak of occurrence in the third decade of life. The most frequent location of tumor was the mandibles (93.2%). Eighty five (96.6%) tumors were recorded as benign and 3 (3.4%) as malignant. Of benign tumors, 62 (72.9%), 20 (23.5%) and 3 (3.6%) cases were of conventional, unicyctic and peripheral types, respectively. In contrast to most previous studies, the most common histologic subtype in the present study was plexiform. Knowledge of the incidence of ameloblastoma and its clinicopathologic features including most common location, gender and age distribution in different ethnogeographic backgrounds is necessary for accurate diagnosis and proper treatment.

Background: The prevalence of non-squamous cell malignant tumors of the oral cavity has not been evaluated in Iran extensively. The aim of this study was to evaluate epidemiological aspects of the oral malignancies with non-squamous cell origin during a 43-year period in the Faculty of Dentistry, Mashhad University of Medical Sciences, Iran. Materials and Methods: In this retrospective study, the records of all patients referred to dental school of Mashhad university of medical sciences in northeast of Iran, during the period 1971-2013 were evaluated. All confirmed samples of oral non squamous cell malignant tumors were included in this study. Demographic information including age, gender and location of the lesions were extracted from patient's records. Data were analyzed using SPSS statistical soft ware, Chi-square and Fisher's exact tests. Results: Among 11,126 patients, 188 (1.68%) non squamous cell malignant tumors were found, with mean age of 39.9 years ranging from 2 to 92 years. The most common tumors were mucoepidermoid carcinoma (33 cases) and lymphoma (32 cases). Non squamous cell malignant tumors occurred almost equally in men (94 cases) and women (93 cases). Most (134 cases) of them were located peripherally with high frequency in salivary glands (89 cases) and 52 cases were centrally with high frequency in the mandible (38 cases). Conclusions: More findings in this survey were similar to those reported from other studies with differences in some cases; it may be due to variation in the sample size, geographic and racial differences in tumors.
