case_images: The clinical differential diagnosis was pyogenic granuloma and peripheral giant cell granuloma (PGCG) (Figure 1).
case_images: Panoramic radiograph showing the presence of a dental implant in the lower left molar region. Insert: increased magnification focusing on the implant in the region of the lower left molar, showing lack of radiographic features that would be compatible with bone involvement.

case_images: The lamina propria was composed of connective tissue containing various multinucleated giant cells surrounded by ovoid and spindle-shaped mesenchymal cells with multiple interspersed small blood vessels (Figure 3).
case_images: Immunohistochemical staining with CD68 showing strong positivity for multinucleated giant cells (original magnification x200).
