GALDEANO ARENAS, Maria et al. Cemento-ossifying fibroma of mandibular gingiva: single case report. Med. oral patol. oral cir. bucal (Ed.impr.) [online]. 2004, vol.9, n.2, pp.176-179. ISSN 1698-4447.

We report a case of a woman presenting a giant cemento-ossifying fibroma depending of the mandibular gingivae. The evolution of the process was 20 years. Cemento-ossifying fibroma is a relatively rare tumour classified between fibro-osseous lesions. This lesion appears within the bone although in some occasions it involves the gingivae soft tissues, as the case we present. It is a slow-growing and well-defined tumorous lesion, because of this, it is considered as a benign lesion. The histologic findings alone may be similar to other pathologies such as osteoblastoma, low-grade osteosarcoma and particularly to fibrous dysplasia. An accurate diagnosis requires careful clinical, radiological and histological correlation in order to make an optimal treatment and an excellent outcome.

Palavras-chave : Cemento-ossifying fibroma; fibro-osseous lesions; gingiva.
