Clinical, radiographic, and histological findings of florid cemento-osseous dysplasia: a case report

Abstract

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissue and involve, essentially, the same pathological process. They are usually classified into three main groups: periapical, florid, and focal cemental dysplasias depending on their extent and radiographic appearances. Radiographically, florid cementoosseous dysplasia (FCOD) appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. The management of the symptomatic patient is more difficult. A case of FCOD occurring in a 52-year-old edentulous Korean female is reported which is rare with regard to race and sex.

Bilateral buccal bone expansion on posterior quadrant of the maxilla.

Fig. 2

Panoramic radiograph shows diffuse, lobular, irregularly shaped radiopacities or cotton-wool appearance throughout the alveolar process of the quadrants of the edentulous maxilla and mandible.

A. Axial CT image shows high density masses in maxilla premolar-molar regions. B. Coronal CT image show high density masses and their relationship to radiopaque masses and bilateral extensions into the floor of the antrum. C. Axial CT image shows high density masses of the posterior quadrant of the mandible. D. Coronal CT image shows high density masses are surrounded by a low density layer.

Fig. 4

There are thick, confluent curvilinear trabeculae with little fibrotic stroma. This lesion showed formation of dense sclerotic calcified cementum-like masses. Periphery of the lesions showed globular or ovoid structures of cementoid appearance involved by thin fibrous tissue (H&E stain, ×200).
