Sturge-Weber syndrome with cemento-ossifying fibroma in the maxilla and giant odontoma in the mandible: A case report

Abstract

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome with vascular lesions of the cerebral meninges, port wine spots on the face, and glaucoma of the eyes; it is a congenital, non-genetic disease whose etiology and mechanisms are unknown. In this report, we describe a rare case of SWS with unilateral large odontogenic tumors in the maxilla and mandible. The histopathological diagnosis of the maxillary bone lesion on biopsy was juvenile psammomatoid ossifying fibroma, which is considered a type of ossifying fibroma of craniofacial bone origin. However, the final pathological diagnosis of the excision was cemento-ossifying fibroma derived from periodontal ligament cells, and we discuss the histopathology in detail. In addition, the mandibular lesion was one of the largest odontomas reported to date. Furthermore, in this case, we suggest the possibility that the maxillary and mandibular bone lesions are not separate lesions, but a series of lesions related to SWS.
