Surgical Pathology Case
 

CLINICAL INFORMATION

  69 year-old man, history of COPD, laryngeal carcinoma with laryngectomy and radiation. 5 years later he had a lung mass in left upper lobe measuring 3.7 x 2.9 that abuts the adventitia of the aortic arch.

GROSS DESCRIPTION

 

The specimen consists of a left upper lobe of lung weighing 268 grams and measuring 19.0 x 9.0 x 5.5 cm. The pleural surface is smooth except over the palpable mass where the pleura is irregularly thickened.  On section the tumor reveals a well-demarcated mass measures 6.5 x 4.0 x 4.0 cm.  The tumor is firm, gray to white with soft yellow to white foci of necrosis and hemorrhage.  The tumor appears to abut, but not invade, the segmental bronchus. No peri-hilar lymph nodes are grossly enlarged or identified.
