Melkersson-Rosenthal syndrome: a case report

The Melkersson-Rosenthal syndrome (MRS) is a rare disease which includes a triad of orofacial swelling, recurrent facial nerve paralysis and plicated tongue. MRS can still be diagnosed when any two of the conditions are present. Because of its rarity, it is usually ignored and misdiagnosed. Herein, a diabetic female patient with this syndrome, previously diagnosed as Bell's palsy, is described. This case report is presented to encourage awareness of this entity among medical practitioners. In addition, the MRS literature is reviewed with respect to incidence, etiology, clinical features, pathology, differential diagnosis and treatment.
