Abstract

Objective: The goal of this study was to reveal clinical and pathologic findings on idiopathic bone cavity lesions (IBC).

Study design: A retrospective analysis of 20 IBC cases diagnosed from 2004 to 2014 from a university-based maxillofacial pathology service was performed and included all pertinent clinical, histologic, and radiographic findings.

Results: Eleven women (age = 36 ± 12.7) and 9 men (age = 23 ± 17.9) diagnosed with IBC were selected for analysis. There was a higher African-American female predilection (40%). Thirty percent of the cases were associated with florid cementoosseous dysplasia (COD) (all middle-aged African-American women). The location of the lesions was mandibular in 85% of the patients. All symptomatic patients (25%) had concomitant COD. Only 1 patient reported previous trauma, and only 1 patient had prior orthodontic treatment. Follow-up period ranged from 1 to 8 years, with only 1 recurrence 3 years after surgery.

Conclusions: The results suggest that IBC concurrent with COD may not be as rare as the literature implies. Clinicians must be attentive to this possible relationship to ensure accurate diagnosis and appropriate treatment.
