We present an 82-year-old female patient with a 2-year history of an infiltrative squamous cell carcinoma (SCC) on her right cheek. The patient was treated with one intralesional photodynamic therapy (PDT) session using 10% 5-aminolevulinic acid solution. We used red light by a non-coherent light source at a light dose of 100 J/cm² and a fluency rate of 100 mW/cm². Complete clinical and histological response was achieved 3 months after the treatment procedure. Cosmetic outcome was evaluated as fair. The patient remains disease free with the absence of any clinical sign of recurrence 16 months after PDT. Long-term follow-up is needed for assessment of recurrences. Optimization of the therapeutic protocol, as well as justification of our results in larger studies are needed in order to elicit safe conclusions.
