Microembolization and resection of a highly vascular pyogenic granuloma.

An unusual case is reported of a hypervascular pyogenic granuloma arising from the mandible which continued to grow postpartum in a person with an associated port-wine nevus. Microembolization of the lesions permitted complete surgical removal with minimal blood loss. This case supports the theory of arteriovenous anastomosis being associated with the pathogenesis of pyogenic granulomas.
