[Solid persistent facial edema of the young adult. Melkersson-Rosenthal syndrome].

We report a case of solid persistent facial oedema in a 18-year-old woman. A biopsy specimen from the nose demonstrating lympho-epithelioid granulomas and an electro-neuro-myographic examination revealing sub-clinical sequellae from an old right facial palsy, led to the definite diagnosis of Melkersson-Rosenthal syndrome (MRS). We focus on the differential diagnosis of persistent facial oedema and outline the difficulties to establish the diagnosis of MRS when all features of the classic triad "recurrent labial edema-facial nerve palsy-lingua plicata" are not present.
