title: [Reddish discoloration of the vascular intima in charred bodies].
abstract: During the autopsy of fire victims, one often sees intensive reddening of the inner vascular layers resembling changes due to putrefaction. To determine the frequency of this phenomenon and the circumstances under which it occurs, in particular the presence of putrescence, signs of vitality and the extent of destruction by the fire, the fire fatalities autopsied at the Institutes of Legal Medicine in Freiburg, Halle and Würzburg were analyzed. In the concrete study, 259 fire deaths were investigated retrospectively and 21 prospectively. The study material included 191 males and 68 females aged 0 to 93 years. Vital exposure to the fire was found in 70%, perimortal exposure in 23 % and postmortem exposure in 7% of the cases. Red discoloration of the intima of the central vessels was seen in 106 victims (41%). This finding is most likely caused by postmortem heat-induced hemolysis, which occurs when the temperature in the body rises above 52 °C due to the effect of external heat. Therefore, a reddish discoloration of the intima cannot be regarded as sign of vitality.
