A peripheral giant cell granuloma mimicking a combined endodontic-periodontic lesion.

Abstract

This case report delineates an instance whereby a peripheral giant cell granuloma mimicked certain features of an endodontic-periodontic lesion. When the area did not resolve following endodontic therapy, and in fact actually increased in size in a relatively short time, the decision to biopsy the area was made. After histologic examination, a definitive diagnosis of peripheral giant cell granuloma was possible. The patient is being monitored postoperatively to ensure no recurrence of the lesion. The relevance of this case report is that it exemplifies the fact that the lesion may be encountered by periodontists, and that the lesion may clinically resemble a mucocele or peripheral ossifying fibroma.
