Patient Comment Read 1 Comment
PUVA can potentially cause skin cancer, just as does natural ultraviolet light. In addition, because of the intensity and duration over which it may be given, patients are at greater risk to develop squamous cell skin cancers and melanomas in treated skin than would otherwise be the case. In addition, excessive aging of the skin manifest as excessive lentigines with atrophy (poikiloderma) is likely to occur in the areas treated. Although rare, serious burns are possible because of inadvertent over dosage of UVA. Patients must limit their environmental exposure to sunlight for 24 hours after taking psoralens.
What Diseases and Conditions Does PUVA Therapy Treat?
There are a number of diseases where PUVA is of proven benefit, including psoriasis (but not psoriatic arthritis), mycosis fungoides (cutaneous T-cell lymphoma), graft versus host disease, and vitiligo. Occasionally, PUVA is also used to treat atopic dermatitis, chronic itching, and certain types of photodermatitis.
