Squamous Odontogenic Tumour - A Paradoxical Pathology

Abstract

Squamous odontogenic tumors (SOTs) are neoplasms being benign, local in origin and infiltrative in capacity that localize to the periodontium. In total, only less than 50 cases have been reported since the first description of SOTs in 1975. The most common site of occurrence of the lesion in the maxilla, incisor area and in the mandible, the bicuspidmolar region. Squamous odontogenic tumors show a characteristic triangular-shaped, unilocular radiolucency of the alveolar bone, with the wide base of the radiolucency localized between the diverging apices of the adjacent roots, radiographically. Here, we report an unusual presentation of the tumour in the periapical region of the mandibular incisor region mimicking radicular cyst clinically but with a major histological variation.
