title: [Schwannoma of the deep peroneal nerve. An unusual presentation in rheumatology].
abstract: The presence of a subcutaneous nodule does not always bother the patient, especially if it is painless and slowly growing. We report on a woman who came to our outpatient clinic for decreased superficial sensitivity of the lateral edge of the left foot. Clinical examination revealed a 2 cm tumor on the antero-lateral side of the left leg. It persisted since 5 years but without symptoms. Ultrasonography on the bedside showed a nervous tumor of the deep peroneal nerve, confirmed by MRI. Pathological examination showed the presence of a schwannoma.
