Metastatic tumors in oral mucosa and jawbones: Unusual primary origins and unusual oral locations.

Aim: To perform clinico-pathological characterization of a large series of oral metastases, collected from 3 main medical centers in Israel and compare findings to data on frequency of primary cancer types in the population.

Materials: Pathology archives were searched for cases of metastatic tumors to the oral soft tissues and jawbones, 1990 - 2016. Metastases to the skin of face or to major salivary glands have been excluded.

Odontogenic sinusitis involving the frontal sinus: is middle meatal antrostomy enough?

Objective/hypothesis: Inflammatory conditions of the posterior maxillary teeth may cause odontogenic sinusitis (OS), which most commonly involves the maxillary sinus due to its proximity to those teeth. The infective process frequently spreads outside the maxillary sinus, involving the anterior ethmoid and the frontal sinuses. The underlying odontogenic condition must be addressed before or during the surgical procedure.

The Spectrum of Oral Lesions Presenting Clinically With Papillary-Verrucous Features.

Purpose: We sought to study the spectrum of oral pathologies presenting clinically with papillary-verrucous features.

Materials And Methods: A 10-year (2007 to 2016) retrospective study of oral papillary lesions was undertaken. All biopsy reports that included a clinical description of papillary or verrucous architecture were retrieved.

Primary Oral Malignancy Imitating Peri-Implantitis.

Purpose: To describe new cases of primary malignancy arising around dental implants.

Materials And Methods: Three patients presented with asymptomatic lesions around longstanding dental implants that resembled peri-implantitis. One case was primary large B-cell lymphoma and the remaining cases were primary squamous cell carcinoma in patients with oral lichen planus.
