Epidermolysis bullosa acquisita--successful treatment with colchicine.

The treatment of epidermolysis bullosa acquisita (EBA) is difficult and often disappointing. We report on the successful treatment of two EBA patients with colchicine. The drug was administered orally at an initial dose of 2 mg/day. After 2 weeks of therapy a dramatic improvement was observed. Most of the cutaneous and buccal mucosal lesions had healed and both of the patients were able to go about their normal daily activities. In the first patient the disease was refractory to dapsone alone or combined with steroids. In the second patient no other treatment was tried. After 6 months a maintenance dose of 1 mg/day colchicine was given. The disease had remained stable in both patients at the time of writing for more than 8 months. No side effects were observed. We suggest that colchicine may be a helpful and safe drug for patients with EBA.
