The patient: A 21-year-old woman in Italy阿拉爱上海

The symptoms: Over the course of three years, the woman would occasionally bleed from her face and palms, despite not having any cuts or scratches. There was no obvious trigger for the bleeding, which would last from one to five minutes上海品茶网. It wasn't linked to a particular physical activity; it could happen when she was exercising or sleeping, for example. However, the patient noticed that the bleeding episodes seemed more severe when she was emotionally stressed.

What happened next: Upon being admitted to the hospital, the patient had been feeling depressed and experiencing panic attacks, and she had become socially isolated because she was embarrassed by the bleeding episodes. While examining her, doctors noticed what they described as "the discharge of blood-stained fluid from her face," according to a case report published in the Canadian Medical Association Journal.上海新茶工作室

Doctors examined the bloody secretion under a microscope and confirmed the presence of red blood cells.

The diagnosis: The blood cells ruled out the possibility of a factitious disorder, or the notion that the woman was pretending to be sick上海各区新茶工作室. It also ruled out various disorders that cause "colored sweat," like chromhidrosis爱上海. Therefore, the doctors diagnosed the woman with hematohidrosis, a rare disease in which "blood sweat" spontaneously discharges through a person's uninjured skin上海后花园论坛. The patient's blood tests showed normal results, as did microscopic analyses of the patient's skin.

The treatment: Doctors prescribed the young woman a daily dose of propranolol, a beta-blocker that's usually used for heart- and circulation-related issues. In their report, the doctors said they opted for this drug because it had previously been used in similar cases. Although the drug noticeably decreased the amount of bleeding, it did not completely stop it.

What makes the case unique: As in other reported cases of hematohidrosis, the doctors could not explain exactly how or why the woman was bleeding through her undamaged skin.

In their report describing this case, they noted various theories that attempt to explain the condition. For example, some think systemic diseases that affect blood clotting may be to blame爱上海官网. Others suggest overactivation of the fight-or-flight system may play a role.

It's also not known how the blood physically passes through the skin. There's no evidence to suggest the blood makes its way through the sweat glands; some reports describe bleeding through the hair follicles上海新茶资源. Furthermore, some patients have also experienced such bleeding in areas that don't have sweat glands, like the tongue or under their nails.
