AB Benign  lung  masses  comprise  a  heterogeneous  group  of  tumors  that  are  defined  by  their  lack  of  malignant  features  histologically  and  their  nonaggressive  clinical  behavior.  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.
