Workup

Laboratory Studies

Laboratory studies are generally not necessary, although a serum calcium level or a parathyroid hormone assay may be indicated to rule out the rare possibility of brown tumor for lesions that are particularly large, recurrent despite adequate surgery, multiple, or associated with systemic signs suggestive of hyperparathyroidism.

Imaging Studies

Periapical radiographs typically demonstrate a cupping out or saucerization of the alveolar bone that underlies a peripheral giant cell granuloma.

Histologic Findings

Intact or ulcerated surface epithelium covers peripheral giant cell granulomas. The underlying connective tissue contains a benign proliferation of granulationlike tissue that supports numerous benign multinucleated giant cells. Abundant extravasated blood is typically noted, and deposits of hemosiderin are seen at the periphery of the lesional tissue. Spicules of woven or lamellar bone may be observed in approximately 35% of peripheral giant cell granulomas. [11]
