Recurrent intravascular papillary endothelial hyperplasia developing from a pyogenic granuloma.

Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular tumour. Many histological features are similar to those of low-grade angiosarcoma, a common, but more serious condition. Clinical and histological differentiation is important to avoid overtreatment of this benign condition. We report on a 34-year-old woman who developed recurrent IPEH at the site of a previously excised pyogenic granuloma.
