[An autopsied case of schizophrenic patient who died from heat stroke].
A male residual schizophrenic out-patient of 65 years old had presented "heat stroke" and died in progressive course of 7 months. His mental condition had been stable and he had kept good drug compliance. In some summer day, he presented high fever and confusion, followed by convulsion. He showed over 40 degrees C high temperature (max 42 degrees C) for about 6 hours. After 10 day's high serum CPK, he gradually presented severe muscle atrophy (proximal dominant), flaccid quadriplegia and brain atrophy (especially in cerebellum). He died from pneumonia. His brain weight was 1,350g. Neuropathological study showed severe loss of Purkinje cell with gliosis. Neurons in dentate nucleus ware entirely lost and a great amount of fatty macrophages were present around the dentate nucleus. Fatty macrophages were observed from cerebellum to red nucleus through superior cerebellar peduncle. These findings have been known as findings of heat stroke. Addition to these findings, this case presented a neuronal loss in the substantita nigra and in the anterior horn of spinal cord and the degeneration of bilateral pyramidal tract. These findings have not been thus far reported, so this case is thought to be the valuable case on considering the variation of neuropathology of "heat stroke".
