Hematidrosis (blood sweat)

Hematidrosis (blood sweat)

Definition Hematidrosis is a condition in which capillary blood vessels that feed the sweat glands rupture, causing them to exude blood, occurring under conditions of extreme physical or emotional stress.Severe mental anxiety  activates the sympathetic nervous system to invoke the stress- Fight-or-flight response to such a degree as to cause hemorrhage of the vessels supplying the sweat glands Dx :- Investigation such as platelets count, platelet aggregation test, coagulation profile and skin biopsy reveal no abnormalities and direct light microscopy of fluid demonstrates presence of normal red blood cells. Investigations also failed to show any vasculitis or skin appendages (i.e. sweat glands, sebaceous glands and hair follicles) abnormalities Treatment :- Effect on the body is weakness and mild to moderate dehydration from the severe anxiety and both blood and sweat loss . The condition is very rare but there are reports in medical literature of successful treatment with beta blockers (propranolol 10 mg) with significant reduction in the frequency of spontaneous blood oozing. The successful use of beta blockers supports the theory that the condition is induced by stress and anxiety yet this etiology is not established yet as the high prevalence of stress and anxiety in the modern era did not change the incidence of this extremely rare disease, suggesting that other co-abnormality also play a key role in this disease. Atropine sulfate transdermal patches have also been used successfully.
