Histologically, it is impossible to distinguish a<unk>  of hyperparathyroidism from other giant cell lesions of bone. Rarely a focal collection of osteoclasts<unk>  may occur in relation to periosteum and be indistinguishable from a peripheral giant cell granuloma (giant cell epulis). The possibility of hyperparathyroidism should be considered in patients with recurrent or multiple giant cell epulides. Radiographically,<unk>  may show no detectable changes or a generalized osteoporosis. Partial loss of lamina dura around the teeth may occur but is not a constant feature. Focal Lesions<unk>  present as sharply defined, round or oval radiolucent areas which may appear multilocular. Such lesions occur more frequently in mandible than maxilla
