Cholesterol Granuloma From a Developmental Odontogenic Cyst: A Report of a Rare Case and a Literature Review.

Dentigerous cysts are the second most common developmental odontogenic cysts that develop around the crown of unerrupted teeth with the maxillary canine region being one of the common sites of occurrence. The cystic lining of this lesion has been shown to develop into ameloblastoma, Muco epidermoid carcinoma, and squamous cell carcinomas. However, the development of cholesterol granuloma (CG) in the cystic lining of a dentigerous cyst is extremely rare. CG is a histological observation distinguished by the presence of a conglomeration of connective tissue and granulation tissue. The condition is predominantly seen in the field of otolaryngology, with very few cases reported in the maxillofacial region, most of which are associated with the maxillary sinus. This article presents the findings of a CG in a 39-year-old male patient that developed within the dentigerous cyst and discusses the possible etiopathogenesis, surgical management, and histological presentation.
