Photochemotherapy for mycosis fungoides: long-term followup study.

A 3-year followup on ten of 12 patients with mycosis fungoides (MF) treated with photochemotherapy (PUVA; psoralens + ultraviolet light) reveals eight patients whose diseases have remained clear while receiving maintenance PUVA. An additional 35 patients with MF have been successfully treated with PUVA. Eight cases of parapsoriasis en plaque have cleared with PUVA. PUVA is indicated in early eczematous and plaque stages of MF. It may be used as adjunctive therapy in tumor-stage MF treated with X-ray therapy or chemotherapy.
