co-occurrence of calcifying odontogenic cyst, aggressive central giant cell granuloma and central odontogenic fibroma: report of a very rare entity and its surgical management

calcifying odontogenic cyst (coc), central odontogenic fibroma (cof) and aggressive central giant cell granuloma (cgcg) are rare pathologic diseases affecting the jaws. while the co-existence of two of them is reported in the literature, existence of all three conditions in one patient is an extremely rare entity. in the present report, initial biopsy revealed fibrosarcoma, therefore mandibular resection was performed for the subject. sectional histopathologic evaluation revealed the co-existence of three conditions through histopathologic evaluation. this report emphasizes the importance of precise microscopical evaluation of jaw lesions and thorough sectional examination of the lesions to reach the precise diagnosis. treatment modalities and follow-up radiographs are also provided to help clinicians manage these entities.
