Treatment of Cutaneous Sarcoidosis With Isotretinoin

• A patient with chronic cutaneous and pulmonary sarcoidosis, unresponsive to oral corticosteroid therapy, was treated with isotretinoin. The patient's cutaneous manifestations of sarcoidosis showed consistent improvement during the course of retinoid therapy. The lesions that responded earliest either resolved or showed the greatest reduction in size. The patient's WBC count increased and her angiotensin-converting enzyme level decreased during the first two months of isotretinoin therapy; both returned to pretreatment levels during the third month of therapy. Pulmonary function tests were unchanged after four months of treatment. isotretinoin may be a useful therapeutic agent for cutaneous sarcoidosis. However, the possibility of spontaneous remission of the disease during the course of therapy cannot be excluded. ( Arch Dermatol 1983;119:1003-1005)
