Systemic Photodynamic Therapy With Chlorine e6 as a Photosensitizer for the Treatment of Nodular BCC: A Case Report.

Introduction: Photodynamic therapy (PDT) is a demonstrated therapeutic method for basal cellcarcinoma (BCC), which is the most common human cancer. Here, we present a case report about systemic PDT with chlorine e6 as a photosensitizer (PS) for BCC treatment. Case Report: A 78-year-old man was diagnosed with a history of a 4-year nodular BCC in the nasal area. The patient was under control and treatment for hypertension and type 2 diabetes. Chlorine e6 was injected intravenously at a 0.08 mg/kg dosage in 500 cc normal saline within 20 minutes. Three hours after injection, laser irradiation was performed with a wavelength of 665 nm, a dosage of 150 J/cm 2 , and an irradiance value of 150 mW/cm 2 . His nodular BCC was completely cured without any side effects after one session of PDT with chlorine e6. Conclusion: Systemic PDT with chlorine e6 as a PS may be safe and effective in removing BCC lesions due to the data obtained in a two-month follow-up.
