The peripheral giant cell granuloma (PGCG) is a benign hyperplastic gingival lesion of unknown aetiology occurring mostly in adults. A few cases have been described in children where a more aggressive clinical behaviour has been observed. In this paper, we report a case of PGCG localized in the anterior region of the maxilla of a 6-year-old boy which developed 6 months following a traumatic event. Early detection and treatment of PGCG is important to reduce possible dento-alveolar complications such as bone loss or displacement of dental germs or teeth.
