Melkersson-Rosenthal syndrome: a review of seven patients.

Melkersson-Rosenthal syndrome (MRS) is a rare disorder consisting of a triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. It is difficult to diagnose and treat. A retrospective review of our MRS patients was performed. The medical files, and treatment, radiologic and histopathologic records of these patients were reviewed. The study group consisted of seven male MRS patients. In four patients, the three classical manifestations were present simultaneously. Neuroimaging examinations found facial soft-tissue thickening and swelling in two patients. The indicators of the disease in our patients were as follows: two had family histories, two had elevated levels of protein in the cerebrospinal fluid, one had an increased immunoglobulin G level in the blood and one had reactive arthritis. All patients responded to systemic corticosteroid treatment. We discuss the genetic, infectious and immunologic factors in the etiology of MRS. Neuroimaging examinations were useful in determining the diagnosis and in determining whether the initial treatment of MRS should be with systemic corticosteroids.
