Case Of Cholesterol Granuloma Research Articles

Cholesterol granuloma embedded in an odontoma of the maxilla

The cholesterol granuloma, a rare entity in the oral cavity, has been given little attention in the dental literature. As a result, there is a lack of accurate data regarding its nomenclature, pathogenesis, and histologic appearance. A new case of cholesterol granuloma in the oral cavity embedded in an odontoma is presented. The literature is reviewed and the nomenclature is clarified.

Cholesterol Granuloma of the Maxillary and Frontal Sinuses

5 cases of cholesterol granuloma are described, 3 within the maxillary sinuses and 2 within the frontal sinuses. The lesions arise from the mucosa and can be recognized on plain films and tomograms of the sinus as opacity, sometimes resembling a mucocele. Radical operation seems to give absolute cure without any recurrence. The pathogenesis is hemorrhage and/or filtration. The closed cavities of the paranasal sinuses provide favorable conditions for cholesterol to become dissociated from the lipoprotein complex and to precipitate and to give rise to a granulomatous reaction.
