[Photodynamic laser tumor therapy with a hematoporphyrin derivative in spinocellular carcinoma of the external ear].

Haematoporphyrine-derivative (hpd) selectively photosensitises malignant tumours following intravenous application. 48 hours after injection of hpd an integral laser-light application of the tumour and the surrounding normal tissue was performed. We report on the successful administration of this photodynamic therapy in a patient with a spinocellular carcinoma of the auricle. 16 days after therapy the tumour showed a complete response without damage of the also irradiated surrounding normal tissue. Apart from a temporary sensitivity to light no side effects of the therapy were seen.
