Background Basal cell carcinoma (BCC) may be difficult to treat by conventional means, particularly if the lesions are large or located in the mid-face (H-zone). Photodynamic therapy (PDT) using topical methyl aminolaevulinate (MAL) may be a good noninvasive option for these patients.
Objectives To investigate the efficacy and safety of PDT using MAL for BCCs defined as ‘difficult to treat', i.e. large lesions, in the H-zone, or in patients at high risk of surgical complications.
