Hybrid lesions comprising central giant cell granuloma and fibrous dysplasia: A diagnostic challenge for pathologist.

Abstract

Hybrid lesions are the lesions consisting of association of features from different pathologies. We present a rare case of hybrid lesion with features of central giant cell granuloma (CGCG) and fibrous dysplasia (FD) involving mandible in a 33-year-old male. Hybrid lesions consisting of features of both benign fibro-osseous lesions and CGCG are very rare. Thus, the purpose of this paper is not only to present a rare case of hybrid lesion with features of CGCG and FD but also to emphasize on the need of careful clinical, radiological and histopathological examination of each and every tissue. There is an important need to report similar and other such cases, which will lead us to understand the interrelationship between these hybrid lesions in a better way and will further clarify their biologic behavior. This will decrease the incidence of misdiagnosis for such cases and will help in preventing recurrences.
