Photodynamic therapy of intravenous injection combined with intratumoral administration of photosensitizer in squamous cell carcinoma.

Cutaneous squamous cell carcinomas (cSCC) is one of the most common types of non-melanoma skin cancer (NMSC), and surgical excision is the primary regimen in most cases. However, in some circumstances of special lesion locations like lips, eyelids or vulva, old age or patient choice non-surgical therapy may be alternative. This is a case of one 93-year-old female cSCC patient who declined surgery. Treatment of hematoporphyrin derivatives photodynamic therapy (HpD-PDT) consisting of both intravenous and topical photosensitizers plus red light irradiation was prescribed. Clinical remission was achieved without evidence of recurrence and most cosmetic function was preserved.
