Recurrent squamous cell carcinoma of the upper eyelid treated with combination therapy of ALA photodynamic therapy and surgery with secondary healing

Cutaneous squamous cell carcinoma (cSCC) frequently occurs in photoexposed areas. Surgery remains the mainstay of treatment in attempts to reduce recurrence, but it must be combined with other therapy because of the limited excision possible in the region of the eyelid, lip, and nose. Photodynamic therapy (PDT) is a relatively new treatment modality that involves the administration of a photosensitizing drug and its subsequent activation by specific wavelengths of light to produce reactive oxygen species that specifically destroy target cells. An 87-year-old female presented 4 weeks after initial resection with recurrent medium-differentiated cSCC measuring 5.2 cm × 3 cm × 2 cm in the left upper eyelid. Subsequent treatment involved palliative resection with an additional 1 cm at 3 margins of the tumor (excluding the bottom edge of the double eyelid line) and 3 applications of PDT using 5-aminolevulinic acid as the photosynthesizing agent in the open wound over a 2-week period. The wound healed well within 6 weeks. During the following 4 years, the patient showed satisfactory progress in both aesthetics and function, with no sign of recurrence or metastasis. Refractory cSCC was successfully managed using a combination of PDT and secondary healing, and functions of the head and face were well protected. These results suggest that such management warrants consideration in clinical settings.
