Neoplastic and Nonneoplastic Benign Mass Lesions of the Lung

Alain C. Borczuk, MDArchives of Pathology & Laboratory Medicine: October 2012, Vol. 136, No. 10, pp. 1227-1233. While most lung neoplasms are malignant, a subset of true neoplasms are benign, the most common of which are pulmonary hamartomas. In addition, a substantial proportion of lung mass lesions are nonneoplastic; granulomas are among the commonly encountered nonneoplastic masses. There is also a group of relatively rare, mainly inflammatory and fibrous tumorlike lesions that are encountered on core biopsy and excisions of lung tissue.
