HISTOPATHOLOGICAL TYPES OF ODONTOGENICKERATOCYST — A STUDY

Abstract

Odontogenic keratocyst (OKC) is the most aggressive odontogenic cyst with a high recurrence rate. They are the most common jaw cysts of odontogenic origin. The histopathological variants are par-akeratinized, orthokeratinized and combination of the two. The present study is a descriptive retro-spective study conducted to evaluate the histopathological variants of OKC. This study was carried out on biopsy specimens over a period of 4 years. 37 patients were included in the study. Age range of the patients was from 14-63 years with the mean age of 35.5 years SD ±11.73. The most common age group of patients was in the 3rd decade of life with 65% males and 34% females. The most common site of occurrence of OKC was the angle of the mandible 40%, anterior mandible 20%. Parakeratinized OKC were predominantly common histopathological type in the region. Malignant transformation was reported in one of the patient of OKC
