MARDONES, Marcelo et al. Primary intraosseous squamous cell carcinoma derived from a keratocystic odontogenic tumour: report of a case and a review of the literature. Rev Esp Cirug Oral y Maxilofac [online]. 2014, vol.36, n.2, pp.82-86. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.05.012.

Primary intraosseous squamous cell carcinoma (PIOSCC) derived from a keratocystic odontogenic tumour (KCOT) is a rare malignant bone tumour that exclusively involves the maxillary bones. It affects middle-age patients, mainly men, and is usually located in the posterior mandibular area. Clinically, it may exhibit classic characteristics of benign odontogenic tumors, though it may also be associated with pain and sensitive alterations. We present the case of an 86-year-old woman who was diagnosed with a PIOSCC derived from a KCOT. The imaging, clinical, and histological characteristics are described, and the importance of taking a biopsy from different parts of a cystic lesion that is characterized by extensive anatomical area involved are discussed.

Keywords : Odontogenic carcinoma; Primary intraosseous squamous cell carcinoma; Keratocystic odontogenic tumour.
