Primary Intraosseous Squamous Cell Carcinoma of the Jaws: 6 New Cases, Experience, and Literature Comparison.

Purpose: To analyze the clinical, histologic, radiologic, therapeutic, and prognostic aspects of 6 cases of an uncommon head and neck malignancy and compare these results with data in the literature.

Materials And Methods: The medical histories of all patients treated in the Maxillofacial Surgery Unit in San Gerardo Hospital (Monza, Italy) for primitive intraosseous squamous cell carcinoma (PIOSCC) of the jaw were reviewed. All patients were considered suitable for inclusion in the study, specifically those whose oral mucosa had not been compromised and who did not have distant metastases.

Ameloblastic carcinoma in a young patient.

Owing to the rarity of publications describing ameloblastic carcinoma, little is known about this entity in pediatric patients. To our knowledge, malignant transformation from an odontogenic cyst into an ameloblastic carcinoma in a pediatric patient has not been documented to date. We present the case of a 14-year-old boy in whom a large osteolytic lesion associated with an impacted right maxillary third molar germ was fortuitously detected by orthopanoramic radiography.
