Abstract

The present article report a rare case of intraosseous dermoid cyst in mandible which clinically and radio-graphicaly presented as mandibular cyst. The diagnosis of dermoid cyst was confirmed histologically. A 20 year old patient was admitted to our Department with the complaint of swelling in left lower jaw with occasional pain. Radiographic examination revealed a radiolucent lesion extending from left 2nd molar to right premolar region. On surgical exploration the lesion was cystic in nature full of hair and keratinized tissues. The tissue was sent for the histopathological examination and macroscopic feature reveal numerous bits of soft tissue. The tissues were creamish brown in color, firm in consistency, with largest tissue measuring 2.5 × 1.5 × 0.5 cm in dimension. Few hair follicles were also evident within it. The histopathology reveal cyst lined by stratified squamous hyperor- thokeratinized epithelium supported by a fibrous connective tissue wall. The cystic epithelium is showing melanin pigmentation in the basal cell layer. Ab-undant onion skin keratin is seen within the cyst lumen. The epithelial lining as well as cyst wall shows numerous skin appendages such as lobules of seba-ceous glands. The underlying connective tissue shows mild chronic inflammatory infiltrate mainly composed of lymphocytes.
