Topical photodynamic therapy (PDT) via topical 5-aminolevulinic acid (ALA) is potentially useful for the treatment of basal cell carcinoma. However, as a photosensitizer used in PDT, methyl aminolevulinate (MAL) can replace ALA, because MAL has more advantages than ALA. We treated two patients with basal cell carcinoma using MAL-PDT. Topical MAL-PDT may be a safe and effective treatment modality for basal cell carcinoma.
