Abstract

Cementoossifying fibroma of the maxilla is an uncommon tumor.
Lesions with fibrous and osseous components include fibrous dysplasia (FD), ossifying fibroma (OF), cementoossifying fibroma (COF) and cementifying fibroma (CF). Fibro-osseous lesions other than FD seem to arise from the periodontal membrane.
We present a clinical case of a young woman referred for evaluation
of a mass in the right cheek. The mass had first appeared 4 years ago and was growing larger inwards. She was treated with surgical resection via a Weber-Fergusson approach.
The physical examination revealed a maxillary enlargement and an
inreaoral lesion which had almost effaced the jugogingival groove. The teeth were moveable and displaced. Imaging studies demonstrated a soft tissue mass in the superior right maxilla which invaded the right maxillary sinus. The differential diagnosis included fibrous dysplasia, osteoid osteoma, osteoblastoma, chronic sclerosing osteomyelitis, maeloblastoma, squamous cell carcinoma of the maxillary sinus, calcifying epithelial odontogenic tumor (Pindborg tumor) and calcifying odontogenic cyst (Gorlin cyst). Histology established a cementoossifying fibroma.
In our case of a cementoossifying fibroma, the differential diagnosis based on clinical manifestations and conventional radiographic studies was controversial. Histologic interpretation was critical, and led to correct treatment.
