IDIOPATHIC BONE CAVITY ASSOCIATED WITH OSSEOUS DYSPLASIA: CASE REPORT

Abstract

A 46-year-old female patient with melanoderma was admitted to the stomatology outpatient clinic with a protruding buccal and lingual cortical bone in the maxillary and mandibular bones. In the physical examination, the mucous membranes remained intact. When palpating, we noticed bone crepitation in the maxilla and mandible bones. The panoramic x-rays showed well-defined radiolucent images without any radiopaque halos extending from the right mandibular ramus to the molar region on the left. In the maxilla, though, the lesions extended to both sides of the molar regions. No root reabsorption was noted. With hypotheses of odontogenic neoplasia, a biopsy was performed in the mandible and maxilla, which revealed hollow cavities devoid of contents. Fragments were submitted for anatomopathologic analysis and showed bone trabeculations of a reactionary aspect. After we assessed both clinical and histopathologic findings, we suggested idiopathic bone cavity associated with fibrous dysplasia. Four-month postprocedure radiograph showed evidence of partial bone neoformation.
