Treatment: Therapy is difficult. No randomized prospective studies have been performed on this rare condition, so only anecdotal therapies have been reported. Topical and oral steroids have been somewhat successful. Chemotherapeutic agents have been used with variable success, including the alkylating agents. Results have been varied, with some patients experiencing long-term remission. Patients all need to be screened for gammopathy and for the development of multiple myeloma. The presence of myeloma portends a worse prognosis.
