Melkersson-Rosenthal syndrome is a triad of recurrent orofacial swelling, 
relapsing facial paralysis, and fissured tongue. However, the classic triad is 
not frequently seen in its complete form. Monosymptomatic and oligosymptomatic 
forms are more common. The histological findings of sarcoid-like granuloma in 
skin or mucosal biopsy specimens support the diagnosis. The course is chronic 
but benign. Treatment is difficult, but intralesional or systemic 
corticosteroids may be helpful.
