Intrathoracic neurogenic tumors comprise 15% to 25% of all primary mediastinal tumors in adults, and 95% originate within the posterior mediastinum.

In most, these are benign slow-growing schwannomas and neurofibromas of peripheral nerve origin. However, patients with neurofibromatosis type 1 (NF1) are particularly at risk for malignant transformation of these tumors and have a poor long-term prognosis.

Clinical Summaries
We present 3 cases of intrathoracic peripheral nerve sheath tumors in patients with NF1 disease.
Patient 1
A 55-year-old man presented with a recent onset of dyspnea and a known posterior mediastinal mass diagnosed 20 years earlier. The mass had increased in size over the past 5 years. Chest radiography revealed a smooth shadow adjacent to the right upper thoracic spine, and computed tomographic (CT) scan confirmed a 4.3 x 3.4-cm low-attenuation mass occupying the right posterior mediastinum. Intraoperative bronchoscopy results were negative. He underwent a posterolateral thoracotomy with resection of a well-circumscribed 5 x 4 x 3-cm mass. The histopathologic diagnosis was neurofibroma. His postoperative course was uneventful, and he is doing well 15
