A 42-year-old woman with no significant past medical history is undergoing a routine physical examination. She states that she is excellent health, does not drink, does not smoke, and runs twice a week. On further questioning, she mentions that the running has become slightly more difficult lately. Radiographic analysis reveals that in the periphery of the left lung, there is a poorly defined mass.
