ABSTRACT
The odontogenic keratocyst has been well documented and extensively studied. It is of particular interest because of its high recurrence rate and aggressive nature. The material for this study consisted of 70 cases of odontogenic keratocysts in predominantly ethnic Chinese patients who were treated from 1981 to 1996. The cases were retrospectively studied to compare characteristics of the lesion in this population with those in previous reports. Most of the patients in this series were 21 to 30 years of age. Association with an impacted mandibular third molar was found in more than 50% of the cases. The recurrence rate was 20% for 35 patients with a follow-up period of at least 5 years. The follow-up period for the whole series ranged from 1 to 16 years. Treatment was surgical enucleation with peripheral ostectomy. There were no significant differences in characteristics with respect to presentation and prognosis between this series and those described in previous publications.

This report presents a review of results from 2370 biopsies of patients up to 20 years of age received over 11 years in the biopsy service at the University of Illinois at Chicago. The computerized data were retrieved and compiled for site, age, sex, race, and diagnosis of the biopsies. The lesions were divided into 1) inflammatory and reactive, 2) cystic, 3) neoplastic, and 4) other anomalies. The patients were divided into three racial groups: whites, blacks, and Hispanics. Whites were in the majority (57%), blacks were the next most prevalent (26%), and Hispanics were the smallest group (17%). Private practitioners were the major source of the biopsies. The predominant site of the biopsies was periodontium followed by the lips. Inflammatory and reactive lesions formed the largest group of biopsies (66.1%) followed by neoplasms (11.2%) and cystic lesions (10.7%). Mucus extravasation phenomenon was the most common lesion followed by periapical granuloma, periapical cyst, dentigerous cyst, pyogenic granuloma, and papilloma. Three malignancies and five ameloblastomas also were found.
