We report a case of Melkersson-Rosenthal syndrome. The case involved an eight-year-old girl. She had experienced left facial paralysis and its spontaneous regression two years before she first came to our clinic with left recurrent facial paralysis and lower lip swelling. Evoked electromyography revealed that the ratio between left and right was 5%. Recovery of facial nerve function was observed after administration of a steroid. Six months later, right facial paralysis occurred, but it disappeared after steroid therapy. Three years after her first visit, right facial paralysis recurred. Because lingua plicata was also exhibited, the diagnosis of Melkersson-Rosenthal syndrome was confirmed. Complete recovery from right facial paralysis was observed after steroid therapy. Although her mother had a history of sarcoidosis, the patient's chest roentgenography, serum angiotensin converting enzyme level, and ophthalmological evaluation for uveitis revealed no signs of sarcoidosis.
