Follicular keratocyst is a variant of odontogenic keratocyst (OKC). It has typical lining of OKC but surrounds the crown of impacted tooth and attached at the cemento-enamel junction, thus mimicking a dentigerous cyst on radiographical examination. Follicular keratocyst is similar to extra-follicular variant in behavior and more aggressive compared to dentigerous cyst. Thus it is important to distinguish this entity from dentigerous cyst. Review of literature shows very few cases of follicular keratocyst. Hereby we are reporting a case of follicular keratocyst which was diagnosed as dentigerous cyst based on clinical and radiographic findings and confirmed diagnosis of follicular keratocyst was made on histopathological examination.
