Topical Application of Photofrin® for Photodynamic Diagnosis of Malignant Cutaneous Neoplasms

The prognosis of patients suffering from malignant cutaneous neoplasms can be improved by early diagnosis. Exact demarcation of tumor margins could contribute to optimum results in surgical excision and reconstruction. The purpose of our study is to evaluate Photofrin® with a new diagnostic procedure, photodynamic diagnosis (PDD), for the detection of Bowen's disease (squamous cell carcinoma in situ), squamous cell carcinoma (SCC), and basal cell carcinoma (BCC).
