Clinical History

62 years-old healthy female without any significant past medical history sought dental care for replacement of a mandibular removable partial denture. Oral examination revealed an edentulous maxilla. Teeth # 22-28 were present in the mandible. In addition, a swelling with a bluish discoloration, well-defined borders and smooth surface measured about 1.0 cm in its largest diameter (Figure 1). The lesion was asymptomatic and the patient was not aware of it. A panoramic film was obtained and revealed a bone concavity corresponding to the area of the clinical lesion. The bone cortex seemed to be intact (Figure 2).

An excisional biopsy was obtained. Five µm paraffin embedded sections were obtained and stained with H&E (Figures 3-13). In addition, PAS and alcian blue stains were also obtained (Figures 14 and 15).
