Pityriasis lichenoides chronica – eine neue Indikation zur PUVA-Therapie?

Abstract
2 patients with long-standing and wide-spread pityriasis lichenoides chronica were treated with orally administered 8-methoxypsoralen and UVA irradiation (PUVA therapy). After 15–21 PUVA treatments the patients were completely cleared. 3 and 4 weeks after the initial PUVA treatment, phase recurrences occurred in both patients. In 1 patient the lesions appeared clinically and histologically as pityriasis lichenoides et varioliformis acuta.
