[Viral implication in immature angiomas. Etiopathogenic hypothesis and immunohistopathologic study of eleven cases]

After assessing research into etiopathogeny of immature angiomas, the authors study immunohistopathological pieces taken from (eleven) patients. Results prove the presence of papilloma virus in the observed tissues, and a particular management of the immunity response. These results evoke a possible viral etiopathogeny at the origin of these lesions.
