[Primary solitary neurofibroma of the chest wall: report of a case resected with video-assisted thoracoscopic surgery].

Primary solitary neurofibroma of the chest wall is rare. We present a 38-year-old man with this disease. The patient was admitted to our hospital because of an abnormal shadow of the left lung in chest roentgenograms. Chest CT scanning showed an extrapleural tumor, 4 x 5 cm in size, which was homogenous and sharply demarcated. The tumor was resected with video-assisted thoracoscopic surgery. The pathohistological diagnosis was neurofibroma originating from the 5th intercostal nerve. His postoperative course was uneventful. Neurofibroma commonly occurs in posterior mediastinum but rarely in the chest wall.
