While performing a pneumonectomy, the thoracic surgeon notes that the hilar lymph nodes are small, 0.5 to 1.0 cm in size, and jet black in color throughout. Which of the following is the most likely cause for this appearance to the hilar nodes?
A Anthracotic pigmentation
B Lipochrome deposition
C Accumulation of melanin
D Hemosiderosis
E Metastatic carcinoma
(2) A 17-year-old driver was involved in a motor vehicle accident. He was thrown from the vehicle and sustained extensive blunt trauma with multiple fractures of the left tibia and fibula, left femur, and right humerus. He was in stable condition until three days after admission, when he suddenly became comatose and died. Autopsy is most likely to reveal which of the following gross pathologic findings?
A Multiple cerebral white matter petechiae
B Large thromboembolus in the pulmonic trunk
C Hematoma in the epidural space
D 500 cc of blood in the pericardial cavity
E Air in the left pleural space with marked atelectasis
