The American Journal of Forensic Medicine and Pathology: December 1991 - Volume 12 - Issue 4 - p 300-305 Buy Abstract We examine the pathogenesis of Wischnevsky's lesions. These gastric lesions were found in 15 of 17 deaths due to accidental hypothermia. Deaths occurred at various minimum temperatures (-2.4–20.4 °C): gastric lesions did not always reflect exposure temperatures. However, all victims exposed to temperatures > 10°C had severe lesions. At temperatures < 5°C, on the other hand, severe gastric lesions were seen in victims younger (43.2 years old) than those with mild lesions (61.0 years old). These findings suggest that gastric lesions develop by exposure to temperatures at which the body's response to short-term stress. Histopathologic examination demonstrated a characteristic finding of cystic dilatation of the capillaries, presumably due to massive reperfusion after functional collapse of the microcirculation in the gastric mucosa. © Lippincott-Raven Publishers.
