• Diagnosis of Lichen Sclerosus based on clinical and/or histological assessment.
• On a maintenance regimen of topical clobetasol for Lichen Sclerosus.  Maintenance is defined as use of topical clobetasol 3 or fewer days per week.  For patients with a new diagnosis of Lichen Sclerosus, they will complete 6 weeks of topical clobetasol ointment twice daily prior to enrollment in the study with transition to use of topical steroids as needed during the study period.
• Residual symptoms despite topical corticosteroid use as evidenced by a patient-administered symptom score of 10 or higher on Clinical Scoring System for Lichen Sclerosus. 
• Residual active lichen sclerosus despite topical corticosteroid use as evidenced by a physician-administered symptom score of 3 or higher on Clinical Scoring System for Lichen Sclerosus. 
• Completed general physical evaluation with primary care provider within 12 months of enrollment.
• Full understanding of the requirements of the study and willingness to comply with protocol.

• Clinically significant abnormal hematology (white blood cell count less than 3 or greater than 10 x 10^9/L, hemoglobin less than 9.5 or greater than 15.5 g/dL, or platelet count less than 130 or greater than 450 x 10^9/L ).  These reference ranges may change if normal reference ranges are changed by the performing laboratory.
• Taking anticoagulant medications (e.g., warfarin, heparin) or clopidogrel (Plavix).
• Taking anti-rheumatic disease medication (including methotrexate or other antimetabolites) within 3 months prior to study enrollment.
