Birthmarks represent good-quality formations on skin which, generally do not cause any problems. The birthmark is limited on the areas congestion of nevusny cages with pigment which are formed as a result of local violation of exchange of melanin and synthesis. As a rule, they slightly act over the skin or flat, smooth, can be sometimes covered with hair.

1. Unfortunately, birthmarks are absolutely not so harmless as can seem. Under the influence of some conditions - long influence of sunshine, continuous friction from clothes, birthmarks can regenerate in malignant tumors. Also birthmarks can form melanomas - rather dangerous malignant disease with fast and early formation of the remote metastases. For this reason all damaged birthmarks need to be deleted with obligatory histologic research. Their rapid growth, increase in quantity, change of form or coloring, emergence of morbidity and bleeding is the important reason to removal of birthmarks. Removal of birthmarks has to be carried out only in special conditions of medical institution because only the doctor will be able safely and qualitatively to make the similar procedure. Before removal of birthmarks determine depth of their bedding that it was possible to pick up correctly depth of influence and way of removal. Now use the following ways for removal of birthmarks: By means of surgical coagulator - electrothermic coagulation. Removal of birthmark is made with use of local anesthesia. To metal thin loop the electric current of high frequency which coagulates surrounding fabrics of birthmark arrives, and cuts off it. Heating of tissues of skin happens instantly, as allows to avoid distribution of cages and bleeding. At the expense of the small sizes of working loop the elimination even of the smallest birthmarks is possible. To remove birthmark, make also its surgical excision. This way usually is required for removal of the most extensive formations. More often removal of birthmark is preferred to be made by means of the modern laser which layer-by-layer processes fabrics within 1-2 minutes under local anesthesia. Liquid nitrogen deletes birthmarks too, freezing them very low temperature (from -100 °C to -180 °C) which causes death of fabrics of birthmarks and destruction. For removal of birthmark carry out rather long exposure for the period of more than 30 seconds by liquid nitrogen, with dense fixing of the applicator under small pressure it is perpendicular over birthmark.
