Hematidrosis, also called hematohidrosis, haematidrosis, hemidrosis and blood sweat, is a very rare condition in which a human sweats blood. The term is from Greek / (αἷμα/αἵματος), meaning blood, and (ἱδρώς), meaning sweat.
== Signs and symptoms == Blood usually oozes from the forehead, nails, umbilicus, and other skin surfaces. In addition, oozing from mucocutaneous surfaces causing nosebleeds, blood-stained tears, and vicarious menstruation are common. The episodes may be preceded by intense headache and abdominal pain and are usually self-limiting. In some conditions, the secreted fluid is more dilute and appears to be blood-tinged, while others may have more opaque, bright red secretions resembling blood.
