[Successful treatment of skin and lung sarcoidosis with fumaric acid ester].

A 61-year old female patient with cutaneous sarcoidosis was treated with fumaric acid esters (Fumaderm). After 12 months of therapy, lesions were markedly improved and treatment was discontinued. 18 months later, the cutaneous lesions recurred, angiotensin converting enzyme (ACE) serum levels were increased and a chest X-ray demonstrated pulmonary involvement. Therapy with fumaric acid esters was again started. The skin showed improvement after 2 months and completely cleared within 17 months, within 4 months ACE levels normalized, and within 10 months radiologic changes markedly resolved. This case demonstrates a possible role for fumaric acid esters not only in the treatment of cutaneous but also systemic sarcoidosis.
