Clinical Summary[edit]

This 15-year-old black female sustained third degree burns involving approximately 85% of the body surface. On admission to the hospital, the patient was taken to the operating room where a tracheotomy was performed and her burned body surface was debrided. After a few days of hospitalization, the peripheral white blood count was 41,000 cells/mm³ with a shift to the left. In spite of intensive therapy, which included administration of fluids and antibiotics, the patient expired on the sixth hospital day.

At autopsy each lung weighed approximately 630 grams and was studded with gray nodules which ranged in size from 3 to 6 mm in diameter. In several areas, these coalesced to form nodules having necrotic-appearing centers.
