From the Research
Hematidrosis is a rare medical condition characterized by the spontaneous exudation of blood through intact skin, often linked to emotional stress and sympathetic nervous system activation, as reported in a recent case study 1.
Definition and Pathophysiology
Hematidrosis, also known as hematohidrosis, is an extremely rare condition where a person sweats blood, occurring when small blood vessels surrounding the sweat glands rupture under extreme stress or fear. This condition is extremely uncommon, with only a few dozen documented cases in medical literature 2. The exact mechanism involves activation of the sympathetic nervous system during extreme stress, causing contractions of blood vessels around sweat glands that eventually rupture.
Symptoms and Diagnosis
Symptoms include bloody sweat appearing on the face, hands, navel, or other body parts, often during periods of intense emotional or physical stress 3. Diagnosis is based on clinical presentation and normal investigation, as laboratory tests are typically within normal limits 1. Microscopic analysis of the secreted fluid can confirm the presence of erythrocytes, supporting the diagnosis of hematohidrosis.
Management and Treatment
Management may include beta-blockers like propranolol, anti-anxiety medications, or atropine-containing topical treatments to reduce sweating, as well as psychological support through therapy 2. Given the suspected psychogenic trigger, early psychological intervention is crucial in mitigating symptom severity 1. A multidisciplinary approach is required for diagnosing and managing hematohidrosis, which lacks definitive diagnostic markers.
Quality of Life and Morbidity
While not life-threatening, hematidrosis can cause significant psychological distress and social embarrassment for those affected 3. Increased awareness of hematohidrosis among clinicians can prevent unnecessary invasive testing, facilitate timely recognition, and optimize patient outcomes 1.
