Histopathological changes in lungs of the mountain snow avalanche victims and its potential usefulness in determination of cause and mechanism of death.

On 28 January 2003 snow avalanche in the Polish Tatras happened, in which 8 people died and 5 were injured. We tried to determine cause and manner of death in 6 fatal victims instead of advanced late post mortem changes in internal organs. Taking into consideration the circumstances of death, we paid special attention to histopathological examination of lungs, extended by Gomori's and AZAN staining. Pattern of the changes was similar to those observed in forensic medicine in cases of asphyxia due to airway obstruction and/or immobilization of chest and abdomen (Perthes' syndrome). Histopathological study with the use of more specific staining methods has a significant diagnostic value during establishing the cause and mechanism of death of the deceased snow avalanche victims with advanced post mortem changes.
