[Primary benign schwannoma of the pleura: Report of 2 cases]

The preferred thoracic location of a schwannoma is the posterior mediastinum. A pleural location is very rare. To date there have been fewer than 20 cases in the literature. We report two operated cases of primary benign pleural schwannoma. The first occurred in a 52-year-old woman who presented with right-sided chest pain and chronic cough. The radiological appearance suggested a hydatid cyst of the lower right lobe. The second case concerned a 37-year-old, asymptomatic man with no past history, who presented with a left posterior mediastinal mass, discovered incidentally on imaging. Both patients underwent complete surgical resection via a posterolateral thoracotomy. The final anatomo-pathological investigation revealed two primary benign schwannomas of the pleura.
