title: Papillary endothelial hyperplasia of adnexal vasculature.
abstract: Papillary endothelial hyperplasia is an exuberant predominantly intravascular endothelial proliferation which may simulate angiosarcoma both clinically and histopathologically. This report describes what, to the best of our knowledge, is a unique case of papillary endothelial hyperplasia within para-ovarian and paratubal veins in relation to a multicystic mesothelial and haemorrhagic ovarian mass. Papillary endothelial hyperplasia should be included in the differential diagnosis of vascular lesions in this site.
