The use of the photodynamic method in the treatment of recurrent basal cell carcinoma on the example of Gorlin-Goltz syndrome-management algorithm.

INTRODUCTION: Conventional methods of basal cell carcinomas (BCC) treatment bring many severe side effects, especially, if they are repeated many times. The aim of this study is to present the clinical effectiveness of photodynamic method in the treatment and prevention of BCC relapses on the face and to propose a management algorithm. METHODS: In a patient with Gorlin-Goltz syndrome (NBCCS) lesions on the face were assessed clinically and with photodynamic diagnostics (PDD), initially and in follow-up every 3 months, for a total of 12 months. Detected BCCs were treated with photodynamic therapy three times every week. RESULTS: In whole follow-up period no clinical relapses were shown. However, in PDD after 6 month in one irradiated and in one initially clinically clear area red fluorescence indicating atypical foci was observed and irradiated additional one time. DISCUSSION: Photodynamic therapy is not limited by previous treatments, can be repeated without adverse events, heals multiple lesions at once and prevents new ones. Because BCC in NBCCS will occur constantly, the implementation of PDD to control the condition of the skin in long-term care should be obligatory. We indicate the validity of using the photodynamic diagnostic and therapy, as a medical procedures of choice.
