Clinical SummaryEdit

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.

Autopsy FindingsEdit

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.

A normal white blood cell count is 4,000 to 11,000 cells per cubic mm.

A shift to the left indicates an increased ratio of immature PMNs (bands) to mature PMNs (segs).

A normal adult left lung weighs 375 grams (range: 325 to 480 grams). And a normal adult right lung weighs 450 grams (range: 360 to 570 grams).

An abscess is a collection of pus (white blood cells) within a cavity formed by disintegrated tissue.

An abscess is a collection of pus (white blood cells) within a cavity formed by disintegrated tissue.

In alcoholics, aspiration pneumonia is common--bacteria enter the lung via aspiration of gastric contents.

An infiltrate is an accumulation of cells in the lung parenchyma--this is a sign of pneumonia.
