title: Pseudotumor associated with polytetrafluoroethylene sleeves.
abstract: We report the case of a patient who was operated on in February 2001. We performed a wedge resection of the upper right lobe. The pathologic examination demonstrated a lung adenocarcinoma (pT2N0M0, R0). We used staple line reinforcement material (ePTFE) during the operation because the patient had an important emphysema. We re-operated in January 2005 because during follow-up we observed a suspicious image that suggested a tumoral relapse. Histopathological study showed extrinsic material compatible with the one used in the original resection.
