Botryoid Odontogenic Cyst with Extensive Clear Cells

Abstract

Botryoid odontogenic cysts (BOC) is an unusual multi cystic variant of the lateral periodontal cyst. We report a case of BOC in a 29-year-old male patient. Radiographic examination revealed a multi locular radiolucency from the mandibular right premolar area, involving almost the whole height of the mandible. Histologically the cystic lesion was lined by a thin 2-4 layered non-keratinised epithelium without rete ridges, with few plaque like thickenings and occasional mural bulges. The most characteristic feature was the extensive clear cells within the cyst lining, in epithelial plaques and among epithelial rests scattered within the fibrous connective-tissue wall
