Successful endoscopic resection of a rare extension of peripheral giant cell granuloma into the infratemporal fossa via the maxillary sinus: A case report study.

Introduction And Significance: Peripheral giant cell granuloma (PGCG) is a benign reactive lesion commonly found in the mandible but rarely in the maxillary sinus and extending to the infratemporal fossa, which poses a major challenge in excision in this case. It can occasionally lead to bone erosion. Complete surgical excision is the primary treatment.
