Long-term efficacy of photodynamic therapy with methyl aminolevulinate in treating Bowen's disease in clinical practice: A retrospective cohort study (2006-2017).

Background: Photodynamic treatment with methyl aminolevulinate (MAL-PDT) is considered an effective and highly recommended treatment for Bowen's disease. However, its long-term efficacy remains to be established, as significant differences have been reported in this respect.

The phenolic compound oleocanthal (decarboxy methyl ligstroside aglycone), which is present in extra virgin olive oil (EVOO), has anti-inflammatory properties.
