Abstract

Benign fibro-osseous lesions are a diverse range of entities that have distinct clinical and radiographic features. They can occur as solitary lesions or concomitant with other pathologies as hybrid lesions. Fibrous dysplasia (FD) accompanied by central giant cell granuloma (CGCG), peripheral giant cell granuloma (PGCG) or peripheral ossifying fibroma (POF) as hybrid lesions, is reported very rarely in the literature. Although we were unable to find any reports of FD with PGCG as a hybrid lesion. Fibro-osseous lesions have certain histopathological features in common with PGCG including multinucleated giant cells. Here we report a 28 year old female with a painless, slow growing and pedunculated swelling of the maxilla for 18 months. Differential diagnosis consisted of FD, cemento-ossifying fibroma (COF), chondrosarcoma and probable PGCG considering radiographic and clinical investigations. Histopathologic findings revealed PGCG and FD as a hybrid lesion. The combination of PGCG and FD has not been reported in the literature so far. © The Author(s) 2023.
