Behandlung eines Carcinoma in situ bei Erythema ab igne mittels photodynamischer Therapie

Abstract

Erythema ab igne (EAI) occurs at skin locations that have been repeatedly exposed to heat or infrared radiation, a single dose of which results in erythema but the intensity of which does not suffice to cause a burn. The clinical picture of EAI is characterized by reticulate erythema, desquamation, and teleangiectasias. Complications of EAI include increasing cutaneous atrophy and predisposition to malignant tumors. The paramount goal of therapy is to eliminate the cause. Individual case reports of EAI with established epithelial dysplasia in the sense of carcinoma in situ have described good response of the neoplastic alterations to topical application of 5-fluorouracil or imiquimod. In our case we achieved successful results with photodynamic therapy.
