title: [What is a hemangioma, what is a malformations? On the differential diagnosis of vascular tumors].
abstract: Systematic and diagnostic classification is important with regard to a carefully directed therapy. Difficulties emerge from the necessary combination of different categories (e.g. location, morphology, etiology). A major consideration is the difference between dilatation (ectasia) and proliferation. We have to distinguish between connatal teleangiectatic nevi (deficient neurovasal transfer), tardive angiectatic nevi (deficient capillary walls) acquired vascular damages, angiokeratotic nevi, lymphectatic nevi, angiomas (primary vascular proliferation), glomangiomas, and malignant vascular tumors.
