ABSTRACT
This article presents two cases of non-melanoma skin cancer treated with photodynamic therapy (PDT). The first case involved a 74-year-old woman with a 4 cm basal cell carcinoma on her right zygomatic region, while the second case involved a 83-year-old woman with a 6 cm squamous cell carcinoma on her left periauricular area. Both patients underwent two sessions of systemic PDT, with chlorin E6 (Photoran) as the photosensitizer, followed by red light illumination. The treatment was well-tolerated with no significant adverse effects. Each three months, the patients showed clinical improvement with partial to complete regression of the tumors. Fluorescence diagnostics and photobleaching control were performed during the PDT sessions to monitor the treatment response. Regular follow-up examinations were conducted, including visual inspections, CT scans, and cytology investigations, which revealed no evidence of any neoplastic processes. These two cases demonstrate that PDT can be a safe and effective treatment option for non-melanoma skin cancer, with good cosmetic outcomes and minimal scarring.
