A peripheral giant-cell granuloma manifestation of primary hyperparathyroidism: report of case

Profuse granulomatous masses of the gingiva frequently occur in patients with gingival and periodontal disease. A 33-year-old female was seen for followup of a previously treated peripheral giant-cell granuloma. Two years earlier, a mass had been removed from the gingiva between the maxillary right central and lateral incisors. Current laboratory test results indicated hyperparathyroidism, and led to the discovery of a parathyroid adenoma. After the gingival lesion, adjacent teeth, and parathyroid adenoma were removed, the patient had no further recurrence of the lesion or signs of hyperparathyroidism.
