This is evidenced by the absence of invasion into surrounding tissue planes or metastatic spread to other structures. In a classic study, Martini1, who investigated the Memorial Sloan Kettering experience, demonstrated that less than 1% of resected lung lesions are benign. More recent reports have shown that despite advances in preoperative imaging and assessment, up to 9% of nodules suspected of being malignant prior to resection are found to be benign.2 Increasing utilization of CT scanning for lung cancer screening as well as for other cardiopulmonary diagnostic purposes has led to an increase in the number of patients being identified with pulmonary nodules. Given the overall low incidence of these tumors, differentiating a benign from a malignant lung mass can sometimes be difficult. Using a combination of clinical tools including a detailed history and physical examination, laboratory workup, radiographic imaging, and tissue sampling techniques, it is often possible to achieve an accurate assessment of a benign lung mass. It is this evaluation and correct characterization of an indeterminate pulmonary nodule that is invaluable in guiding treatment planning as well as assessing the overall prognosis of the patient.
