Massive maxillary peripheral giant cell granuloma in a 12-year-old male: Case report

Peripheral giant cell granuloma (PGCG) is a benign, hyperplastic reactive lesion arising from the mucoperiosteum of the alveolar ridge following chronic irritation or trauma. It is characterized by the presence of multinucleated giant cells. We report a 12-year-old male with massive maxillary PGCG where ultrasonography was used as the first line of investigation to determine the severity and vascularity of the lesion based on differential diagnosis. The ultrasonographic findings showed well-defined hyperechoic multifocal echogenic areas and low-resistant spectral waveforms obtained on Doppler were consistent with benign soft tissue lesions. The histopathological examination showed that of a typical multinucleated giant cell with the diagnosis of PGCG.
