An asymptomatic 78-year-old man presents with a spiculated mass in the lingula. He is a former cigarette smoker of 45 years, and he has a history of prostate cancer status post-prostatectomy in 2007. PET scan showed increased uptake in the mass but no evidence of distant metastatic disease. He underwent wedge resection with mass, which was grossly 3 cm, soft, and yellow-tan in color.
