Dentinogenic ghost cell tumor-a rare case report with review of literature.

Dentinogenic ghost cell tumors (DGCT) are very rare tumors considered as solid variants of calcifying epithelial odontogenic cysts (CEOC). They are locally invasive neoplasms and their main characteristic features are ameloblastoma like odontogenic epithelial proliferation, an aberrant keratinization in the form of ghost cells and dysplastic dentin. DGCT occur as two forms intraosseous (central) and extra osseous (peripheral), of which more aggressive intraosseous variety requires careful monitoring and aggressive local resection to prevent recurrence. This paper discusses a case of a 14-year-old male patient with a complaint of swelling in his right mandibular premolar molar region since 4 months and missing permanent right mandibular canine and first premolar was also observed. The lesion was diagnosed with radiological, cytological and histopathological investigations which revealed it to be rarest entity.

Adenomatoid odontogenic tumour: tumour or a cyst, a histopathological support for the controversy.

Adenomatoid odontogenic tumour (AOT) is a well-established odontogenic tumour with various clinicopathological variants. AOT quite frequently mimics an odontogenic cyst commonly a dentigerous cyst. Histologically a cystic component of AOT has been described in the literature. In the present paper we review the literature for the AOTs arising in an odontogenic cyst and add to the literature a case of cystic AOT. The present review is aimed to provide an insight to the varied demographic profile, clinical behavior and prognosis of cystic variant of AOT.
