ABSTRACT
Two comparable groups, 60 patients in each, were included in the study. Localization and area of the wounds, as well as basic treatment were equal in these groups. Patients of the main group received the additional photodynamic therapy with chlorine photosensibilizing agent. It led to the shortening of the wound clearing time and stimulation of the epithelisation together with fast decrease of bacterial load. Morphologic analysis showed faster inflammation decrease and granulation as well as lesser microcirculatory disorders in wounds treated with photodynamic therapy. Moreover, cicatrixes were more elastic and gentle in these patients.

Clinical and histological examinations of 1562 patients with trophic and advanced radiation ulcers were carried out during 30 years. Malignant transformation of the ulcers has been revealed in 14 of them: sarcoma--in 1, and cancer--in 13. From all the patients with advanced radiation ulcers, malignant transformation was detected in 7.07%, and in cases of ulcers of the other genesis--in 0.81% of cases. Malignant transformation of ulcers of non-radiation genesis occurs on the average after 19 years, and of radiation one--after 3.8 years. Early diagnosis of skin cancer, at the site of the ulceris rather difficult and depends thoroughly on oncological alert and timely morphological examination of various skin areas. A new, rather perspective and relatively simple method of treatment for ulcerative forms of cancer of the skin is photodynamic therapy (PhDT). This method showed to be effective even in those patients who failed conventional methods of treatment (relapses), or had contraindications. PhDT has broaden the armory of the oncologists and oncodermatologists for treatment of complicated forms of cancer of the skin.
