Abstract
To study characteristics of Melkersson-Rosenthal syndrome (MRS) patients with facial palsy (FP) and differences in patients treated at the Departments of Otorhinolaryngology and Dermatology. Clinical picture of MRS was studied from patient charts at two departments. Patients with FP received a questionnaire and were examined. Tissue biopsies were searched for non-necrotizing granulomatous infiltrations typical of MRS and blood DNA for UNC-93B1 gene mutations predisposing to herpesvirus infection. At the Department of Otorhinolaryngology, all 18 MRS patients had FP, 9 the triad form. Two patients revealed non-necrotizing granulomatous infiltrations during acute edema episodes; another two had association with uveitis. Edema was rarely persistent and did not dominate the clinical picture. No UNC-93B1 mutations were found. At the Department of Dermatology, 2 patients had triad MRS and 15 had monosymptomatic granulomatous cheilitis with persistent edema and typical MRS histology. The clinical picture of MRS with FP differed from the current knowledge of edema-dominated MRS. More studies focusing on MRS with FP would broaden our understanding of the syndrome.
