Photodynamic therapy for conventional treatment resistant actinic keratosi

Abstract

Introduction: Actinic keratosis (AK) is a common skin disease, presumably caused by long term sun exposure, and capable to undergo malignant transformation. Here, we present a case of AK successfully treated with PDT. A 75-years old male patient presented with AK on the head. The patient had received conventional treatments for the last 3 years, with no satisfactory outcome. The patient was treated with methyl aminolaevulinate based PDT in three sessions. After 3 months of the treatment, the patient illustrated complete response to the treatment. The patient has been followed up for 2 years and no recurrence has been observed. PDT has a rapid response and significantly effective for improving Actinic Keratoses lesions.
