Successful treatment of cutaneous langerhans cell histiocytosis with thalidomide.
Langerhans cell histiocytosis (LCH) represents a group of rare histiocytic syndromes characterized by tissue infiltration with dendritic cells. The management of LCH is difficult as these disorders respond inconsistently to immunosuppressive and chemotherapeutic strategies. Thalidomide (N-phtalimidoglutarimide), initially used as a tranquilizer, has recently been used in the management of several inflammatory skin diseases. We describe the case of a 38-year-old male with mucocutaneous LCH. A treatment course with 6 cycles of 2-chlorodeoxyadenosin (cladribine) was initiated. This was well tolerated but withdrawn after 6 months to prevent secondary malignancy. A partial remission was seen. Subsequently, a treatment course with thalidomide 200 mg daily was started. This therapy resulted in a significant improvement of the mucocutaneous lesions within 4 weeks and complete healing was achieved after 3 months. Treatment was then successfully continued with daily doses of 100 mg to prevent relapse. In conclusion, thalidomide monotherapy represents an effective, safe and well-tolerated treatment option that should be considered as first-line therapy for mucocutaneous LCH.
