Coexistence of hyperparathyroidism and peripheral giant cell granuloma of the jaw: A rare case report.

Peripheral giant cell granuloma (PGCG) known as "giant cell epulis" is a benign, reactive exophytic gingival lesion that accounts for less than 10% of all gingival lesions. PGCG affects females more than males with middle age predilection. Till now the etiology of PGCG remains unclear but various factors that can cause PGCG include poor oral hygiene, food impaction, following an extraction, dry mouth, hormonal disturbance, and hyperparathyroidism. The reported recurrence rate of the lesion is 5.0%-70.6%. The present case report describes the rare case of PGCG with primary hyperparathyroidism in a male patient with a history of swelling in the mandibular anterior region.
