Abstract
To record the potentially serious side-effects of melanoma and non-melaoma skin cancers and ocular damage following long-term PUVA chemotherapy, we re-examined 198 of 242 patients. These comprised: 90 with psoriasis, 27 with parapsoriasis, 19 with cutaneous T-cell lymphoma, 23 with vitiligo, eight with cutaneous mastocytosis, 16 with atopic dermatitis, three with prurigo nodularis, two with polymorphous light eruption and 10 with pruritus of chronic renal failure on dialysis, treated between 1977 and 1987 in our department. During the 10-year period, 11 patients died of unrelated disease. None of the patients reviewed had previous skin cancer or had been treated with arsenic, methotrexate or ionizing irradiation before PUVA treatment. None of the patients were children under 16 years of age. The mean age was 54.5 years, the sex ratio 102:96 (M:F). The mean cumulative dose of UVA for the whole group was 169.5 J/cm2. One patient with psoriasis, psoriatic arhropathy, ankylosing spondylitis and Crohn''s disease, who was on azathioprine for 6 years, developed squamous-cell carcinoma on the left lower leg. Another patient with pustular psoriasis, who received PUVA treatment to her palms and soles only, developed malignant lentigo of Hutchinson on the right lower leg. PUVA lentigines were found in about 20% of patients. All patients had a yearly ophthalmological examination. None of them developed cataracts, lens opacities or had impairment of their visual acuity.
