Photochemotherapy for pustular psoriasis (von Zumbusch).

Photochemotherapy (PUVA) with oral methoxsalen and UV-A was instituted in 8 patients with generalized pustular psoriasis (von Zumbusch). Complete clearing of skin lesions and of systemic symptoms was achieved in all patients. Patients who had been on systemic treatment prior to PUVA had to be treated with considerably more UV-A energy than patients who had received topical therapy alone. Seven patients were kept in complete remission by maintenance therapy for an observation period of up to 1 1/2 years. Side effects of systemic pre-PUVA treatment resolved during several months of maintenance therapy.
