Pathological spectrum of the lung in cases of violent death: Part II. Clinicopathologic correlation.
The correlation between the type of pathological lesion of the lung and the circumstances which encompass their evolution in 66 cases of violent death have been examined. Pulmonary lesions have been classified into four groups. 1. Inflammatory alveolar lesions without a diffuse interstitial involvement (IAL) which result from direct aggressions in subjects of advanced age. 2. Inflammatory alveolar lesions with a diffuse interstitial affectation (IALW) which are more frequent in younger subjects having a higher defense capacity and with severe lesions requiring admission to an intensive care unit. 3. Edemohemorrhagic lesions (EHL) appearing as a precocious lesion at any age. 4. Unspecific chronic lesions (UCL) previous to the aggression and without any relationship to death. The most obvious feature noted was the frequent occurrence of certain types of acute pulmonary lesions indicative of the rapid and extensive capacity of the lung to react to a lesion agent even when death follows rapidly after the aggression. The scarcity of acute interstitial lesions among the older group can be related to a diminution of biological defense activity leading to a less vigorous response; on the contrary, diffuse lesions of the wall seem to be related to an excess of defense mechanisms, determined more by age, severity of lesion, and type of medical assistance received than by a specific type of aggression.
