title: [Subcutaneous tumour in an adolescent].
abstract: A 13-year-old adolescent presented with an enlarging subcutaneous mass beneath the right eyebrow. Clinically suspicious for dermoid cyst or pilomatrixoma, it was decided to remove the tumour completely. Based on histopathological examination the diagnosis of intravascular papillary endothelial hyperplasia (IPEH) was made. Histopathological features are discussed with regard to the possible pathogenesis.
