Squamous odontogenic tumor-like proliferation in a radicular cyst: A case report.
The squamous odontogenic tumour is a rare benign neoplasm whose aetiology remains unknown. It usually appears in the jaw and its origin could be related to the ephitelial remnants of Malassez. Histologically comprises numerous islets of squamous, non-keratinized, well-differentiated and rounded epithelial cells a fibrous stroma without signs of atypical cells. There is a non-neoplastic lesion with the same histological pattern than the squamous odontogenic tumour. This entity is characterized by squamous odontogenic tumour proliferations isolated into the cyst wall of an odontogenic cyst. It is rare and has a benign behavior. It has been suggested that these epithelial proliferations could be the former expression of the neoplastic form. It is very important to carry out clinical and radiological controls periodically. So far it has not been documented any change towards a squamous odontogenic tumour nor toward malignancy in a squamous odontogenic tumour like proliferation. Key words:Radicular cyst, squamous odontogenic tumour.
