Abstract
Maxillary sinus osteomas are rare benign tumours with a poorly documented clinical evolution. Their craniofacial localization may be part of a syndrome. We report a case of maxillary sinus osteoma associated to a mucocele and a cyst probably of dental origin, with no sign of associated Gardner syndrome. A 52-year-old woman consulted for chronic maxillary sinusitis and an oral vestibular fistula. The CT-scan suggested a mucocele with reactive bone formation. Macroscopically, a pediculated bone tumour was found next to a mucocele, and to a cyst probably of dental origin. The anatomopathological examination led to a diagnosis of cancellous osteoma. Several hypotheses have been made on the etiology of sinus osteomas. When identified, screening for Gardner's syndrome should be implemented because of the associated risk for colic malignancy.
