title: Papillary endothelial hyperplasia in angiokeratoma.
abstract: Papillary endothelial hyperplasia (Masson's tumour) is a reactive proliferation of endothelium producing papillary structures with fibrovascular cores. Dilatation, stasis and accompanying inflammation have been incriminated as the inciting events, evident by the presence of this lesion in haemorrhoids, urethral caruncles and laryngeal polyps. We present here a case of papillary endothelial hyperplasia in angiokeratoma hitherto undescribed despite sharing common etiopathogenetic features of dilatation and stasis with other aforementioned lesions.
