Cheilitis granulomatosa Miescher: treatment with clofazimine and review of the literature.

Cheilitis granulomatosa Miescher is a rare condition of unknown cause characterized by intermittent lip swelling that gradually persists and causes cosmetic deformity. We report the case of a young woman with cheilitis granulomatosa as a monosymptomatic manifestation of Melkersson-Rosenthal syndrome successfully treated by the antileprosy agent clofazimine, and propose clofazimine as an alternative treatment in cases refractory to corticosteroids. The differential diagnosis and current methods of treatment are summarized, and the literature is reviewed and discussed.
