Intravascular papillary endothelial hyperplasia of the orbit.
Intravascular papillary endothelial hyperplasia is a rare vascular benign tumour bearing some similarities to malignant angiosarcoma. The case reported here in a 20-year-old girl is of particular interest because the orbital tumour, despite its entirely benign nature, invaded the temporal fossa through the lateral bone of the orbit.
