Relative frequency of localized reactive hyperplastic lesions of the gingiva: a retrospective study of 1675 cases from Israel.
Peripheral giant cell granuloma (PGCG) is a common reactive gingival lesion that histologically resembles the central giant cell granuloma, and is a central lesion of the jaws. Occasionally, central giant cell granuloma-like lesions may be seen in association with hyperparathyroidism. Rarely, PGCG-like lesions have been described in a background of hyperparathyroidism. We describe the case of a 91-year-old woman taking teriparatide for the treatment of osteoporosis and presented with a peripheral giant cell granuloma of the mandibular posterior area.
