RESUMO
Primary sarcoma of a muscular artery is extremely rare. A review of the literature revealed only one report of a sarcoma originating in a coronary artery. We report a case of fatal cardiac infarction caused by an intimal sarcoma originating in the left coronary artery which exhibited immunophenotypic features that were consistent with rhabdomyosarcomatous differentiation.

A previously healthy 9-year-old Japanese boy with a 4-day history of vomiting and headache died suddenly and unexpectedly. An external examination revealed no abnormalities other than foam around the mouth and nose. An internal examination revealed severe pulmonary edema and hemorrhagic hemangiopericytoma arising from the choroid plexus of the right lateral ventricle. The cause of death was thought to be neurogenic pulmonary edema caused by the rapid growth of a hemangiopericytoma, with intratumoral hemorrhage.

Gastric arterial rupture is a rare but serious and potentially fatal complication of percutaneous endoscopic gastrostomy (PEG). We report a case in which insertion of a needle during PEG caused iatrogenic rupture of the left gastric artery.

An autopsy case of fatal hyperthermia in a state of excited delirium is reported. On a hot summer night a 39-year-old man was suspected of being a rapist, and police officers and several men attempted to arrest him. He vigorously resisted, but after a 20-min struggle he was ultimately forced into a prone position on the ground with his arms and legs restrained by police officers. He collapsed shortly after being arrested and was taken to a hospital, but was pronounced dead on arrival. His rectal temperature measured 2.5 h after death was 40 degrees C. At autopsy the body showed a severer degree of postmortem change than after death at a normal body temperature and a similar postmortem interval. Autopsy revealed abrasions and subcutaneous hemorrhages of the head, face, arms, and legs. The heart was dilated and exhibited subendocardial hemorrhages in the left ventricle. The brain and both lungs were congested. Microscopic examination of the lungs revealed intraalveolar edema and hemorrhages. The skeletal muscles showed contraction band necrosis and hyaline degeneration. The liver showed diffuse coarse-droplet fatty infiltration of hepatocytes. Neither addictive drugs nor alcohol were detected from the blood or urine. The suspect was concluded to have died of fatal hyperthermia in a state of excited delirium.
