Fibrous dysplasia (FD) is a developmental tumor like condition that is characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Central giant cell granuloma (CGCG) is described as a benign lesion affecting the mandible and maxilla that consists of a massive fibrohistiocytic proliferation with numer...

Follow-up radiographs of the distal radius revealed consolidation of the grafted bone and hydroxyapatite, and no recurrence of the lesion (Fig 2). A brown tumour presents with areas of radiolucency particularly in the facial bones, pelvis, ribs and femur (Doğan et al., 2004). Our patient had an unusual location of this disorder although this has been documented before (Resnick, 1974). As usual,...

Giant cell reparative granuloma (GCRG) involving the small tubular bones of the hands and feet is a rare entity that can have a wide range of morphologic presentations and can be confused with more aggressive tumors. Awareness of this lesion is important to avoid diagnostic errors and potential mismanagement. We report three cases of GCRG that involve the small tubular bones of the hands and fe...

A 9-year-old girl with a solid variant of an aneurysmal bone cyst in the 3rd lumbar vertebra showed a good response to low-dose radiation as the only treatment. The solid variant of aneurysmal bone cyst is thought to be a reactive response to intraosseous hemorrhage and is also called giant cell reparative granuloma or giant cell reaction. These lesions in the jaw and the short tubular bones of...

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...
