The common classifications of cutaneous vascular tumors are based on morphological, clinical and histological criteria. In the case of vascular proliferates that appear clinically as a "tumour", it is often unclear whether they are:...a tumor. Another special etiopathogenetic and clinical feature is the infant hemangioma.

Structural composition of vascular tumours:

  • Vascular orientation (intra- or perivascular)
  • Architecture (lobar or nodular/diffuse)
  • Endothelial pattern (single layer or papillary multilayer)
  • Vascular structure (organoid capillary vessels or bizarre vascular structures).


  • Immunohistologically intravascular angiomas are defined as descendants of blood or lymph vessel endothelia, perivascular angiomas as descendants of smooth muscle cells or pericytes.
  • Markers for endothelia are: CD31, ERG, FLI-1, factor VII-related antigen/v. Willebrand factor), CD34, Ulex europaeus.
  • Markers for lymphatic endothelia are: D2-D40/Podoplanin, Prox1, LYVE1, VEGFR3 (vascular endothelial growth factor-3)
  • In perivascular angiomas, reactivities for alpha smooth muscle actin, desmin, calponin, caldesmon are found.
