ABSTRACT:
Background: Photodynamic therapy (PDT)
is a treatment for non-melanoma skin cancer. In recent years, its use has
expanded to new indications. Viral warts (VW) are some of the most promising.
Methods: A retrospective, descriptive, observational study was carried out.
Patients who did not respond to cryotherapy were selected and were occluded
with methyl aminolevulinate (MAL) for three hours and they were illuminated
with red light. Tolerance to treatment was evaluated using a visual analog
scale for pain (from 0 to 10). Results: A total of 15 patients with 134 VW were
treated. A complete response was obtained in 13 of 15 patients (87%) and in 127
of 134 lesions (95%). The mean number of sessions was 3.1 (range 1 to 6) and
the average pain score was 3.1 (range 0 to 8). Conclusions: PDT is a treatment
that offers good results in the treatment of VW that are resistant to routine
treatment. The treatment was well tolerated in our patient group.
