Melkersson-Rosenthal syndrome in the context of sarcoidosis: a case report.

Background Melkersson-Rosenthal syndrome is a rare disease characterized by the triad of recurrent orofacial swelling with facial paralysis and fissured dorsal tongue. Histologically, noncaseating granulomatous inflammation occurs that confirms the diagnosis. Overlaps between granulomatous diseases such as sarcoidosis and Crohn's disease are described. Systemic corticosteroid therapy is the treatment of choice for acute attacks. Case presentation We here present a case of a 59-year-old White woman suffering from Melkersson-Rosenthal syndrome with a past history of sarcoidosis on therapy with leflunomide in combination with low-dose tacrolimus successfully treated with the anti-leprosy drug clofazimine after failure of systemic steroid therapy. Conclusions We propose clofazimine as an alternative treatment in steroid-refractory cases.
