Unicystic ameloblastoma presenting as multilocular lesion: A case report.

Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histological examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumour growth. In this case report we present a uncommon multilocular unicystic ameloblastoma encountered in a 40 year old female patient.

Dentigerous cyst associated with impacted permanent maxillary canine.

Odontogenic developmental cysts of jaws usually presents as asymptomatic lesions. Dentigerous cyst is one of the variety of these cysts which may grow to a large size intraosseously within jaws before it manifest clinically. Numerous immunohistochemical and molecular marker studies have been carried out for this lesion to understand its etiopathogenesis and aggressive behavior. Another reason being its potential to transform to ameloblastoma and squamous cell carcinoma. We present a case of dentigerous cyst associated with impacted maxillary canine manifesting as a unilateral swelling of midface region.

Oral submucous fibrosis : current concepts in etiopathogenesis.

Oral submucous fibrosis (OSF) is now accepted globally as an Indian disease, having highest malignant potential than any other oral premalignant lesions. The understanding of the exact role of alkaloids and other etiological agents with respect to pathogenesis will help the management and minimize the blind clinical trials and treatment modalities. This article provides an overview of the etiopathogenesis with stress on the recent concepts related to this chronic “Indian Disease”.
