    Abstract:
    In a morning in January, a male in his early sixties was found dead in an outdoor parking area. The minimum temperature during the night before he was found dead was estimated to be 4.0 degrees C. Autopsy revealed the pinkness of hypostasis, slight abrasions and bruises on the face and the extremities, collapse of the lungs, and slight gastric submucosal hemorrhage. Histologic examination revealed compact arrangement of cardiac muscle fibers and cytoplasmic vacuolation in the adenohypophysis. Toxicologic examination demonstrated hyperacetonemia (51.2 microg/mL). Ubiquitin, one of the stress proteins that are induced by several stimuli, including severe cold, was detected in several organs. We concluded that the cause of his death was lethal hypothermia. In addition, hemorrhages were observed in the subfascial and/or intramuscular parts of the pectoralis minor, first intercostal, and iliopsoas muscles. Although it has been reported that iliopsoas muscle hemorrhage can result from hypothermia, there have been few reports concerning hypothermia-associated hemorrhages of the pectoralis minor and/or intercostal muscles. We presumed that intense shivering and/or effort ventilation during the course of lethal hypothermia might cause these muscle hemorrhages.
