−	It was determined at autopsy that the patient suffered from pulmonary tuberculosis with widespread dissemination throughout the body. The left lung weighed 620 grams and the right lung 1230 grams. These were characterized by marked pulmonary congestion and pulmonary edema. In addition, multiple gray-white nodules ranging from pinpoint size up to 1 cm were diffusely distributed throughout the lung parenchyma.

-This 70-year-old man was admitted to the hospital with a history of upper abdominal pain, anorexia, nausea, and general malaise, all of approximately three weeks' duration. His hospital stay was characterized by fever and severe respiratory distress. There were multiple densities in the patient's chest x-ray consistent with pneumonia and examination of a stained sputum specimen showed acid fast bacilli. Despite intensive therapy, the patient progressively deteriorated and died 14 days after admission.

 File:IPLab1Tuberculosis1.jpg|This is a gross photograph of a cut section of lung from this patient with disseminated tuberculosis. The numerous small white nodules scattered throughout this lung tissue represent individual tuberculosis granulomas.
