[Subacute cutaneous lupus erythematosus. Treatment with sulfone].

We present a patient with annular subacute cutaneous lupus erythematosus who was successfully treated with low doses of sulfones. A very photosensitive cutaneous eruption and scanty systemic symptoms are characteristics. Also there are ANA and anti-Ro positives but the anti-DNA antibodies negatives as immunological markers. The treatment with sulfones will be a valid treatment when safer drugs have failed.
