Since the physiological response to exercise includes cutaneous vasodilation and sweating any limitation of such a response can cause rapid hyperthermia and thus heat stroke. One such condition is extensive burns healed by cicatrisation of the skin where the scar and grafted skin surface do not have functional sweat glands and are unable to lose heat in response to high temperatures. The authors report one unique case of a female marathon runner with exertional heat stroke who had recovered from deep second and third degree burns over approximately 50 of her body a few years ago. Introduction Exertional heat injuries are known to affect marathoners and army recruits under hot and humid environmental conditions 1 2 . This occurs when heat production exceeds the body s ability to dissipate heat. Since peripheral vasodilation and sweating can dramatically increase heat loss the lack of these physiological responses seriously predisposes those with these conditions to exertional heat injuries. The authors report a unique case of a female marathon participant who suffered exertional heat stroke possibly caused by her inability to swe at over a large surface area of her body and thus accumulating heat rapidly. Case report A 36-year-old female who had been running a marathon was brought to the emergency department ED . She was brought in by the Civil Defence ambulance after she had .
