Squamous Odontogenic Tumor Mimicking an Intra-Osseous Malignancy: A Rare Case Report

Aim: Squamous Odontogenic Tumor (SOT) is a rare odontogenic epithelial neoplasm, first described by Pullon et al. This lesion was classified as a distinct pathological entity by the World Health Organization (WHO) in 1992. The pathogenesis is still controversial with possible origin from epithelial rests of Malassez or rests of Serres. It is a locally infiltrative and occasionally destructive lesion.

Case Presentation: We report a case of a 34-year-old male who was referred to our centre with complaint of fracture of mandible which was subsequently diagnosed as a Squamous odontogenic tumor.

Discussion: Histologically, the tumor was characterized by islands of bland terminally differentiated squamous epithelium with keratinization or calcifications. The patient underwent resection of the lesion and is under follow up since then.

Conclusion: An extensive literature review showed that less than 50 cases have been reported worldwide with minority of cases in Indian sub-continent.
