Squamous odontogenic tumour: report of two cases.

Squamous odontogenic tumour is a benign odontogenic tumour composed of a well-differentiated squamous epithelium immersed in a fibrous connective tissue stroma. It is a rare tumour and a recent literature review yielded only 36 cases. Two cases of squamous odontogenic tumour are presented, 1 located in the maxilla and the other in the mandible: 1 of these cases showed a periodontal involvement. The radiographic picture was fairly characteristic in 1 case, with a radiolucent lesion between the roots of the second mandibular premolar and the first molar, while, in the other case, it was possible to observe the presence of a lesion located at the apex of a molar. The tumours were enucleated, and no recurrences were observed after 5 years.
