Broad area photodynamic therapy for treatment of multiple basal cell carcinomas in a patient with nevoid basal cell carcinoma syndrome.

We report a case of a 73-year-old man with nevoid basal cell carcinoma syndrome who was referred to us with multiple basal cell carcinomas on his face and chest. The patient underwent photodynamic therapy utilizing a 1-hour incubation of Levulan Kerastick delta-aminolevulinic acid 20% topical solution applied to the full face and illumination with a BLU-U blue light source (10 J/cm2) every 2 to 3 months for a total of 4 treatments. This treatment strategy resulted in multiple benefits, including reducing the number and size of his existing basal cell carcinomas, improving the appearance of previous surgical scars, and decreasing the rate of tumor development.
