Abstract

The morphohistological picture of skin biopsy specimens from patients with cutaneous vasculitis is presented. Dilatation of dermal vessels and increase of their numbers, increase of perivascular lymphocytic infiltration of the derma in comparison with the parameters in biopsy specimens of the skin from healthy volunteers indicates neoangiogenesis and pathological dilatation of the dermal capillaries. High concentrations of matrix metalloproteinase 9 (MMP-9) and its homogenous dissemination in the specimens from patients with dermal vasculitis presumably indicate the regulatory role of MMP in extracellular matrix remodeling and neoangiogenesis.
