Hematohidrosis is a rare clinical condition of sweating blood. A 13-year-old boy was presented to the department of dermatology with a history of spontaneous bleeding from skin since January 2007. During examination, it disappeared as soon as it was mopped leaving behind no sign of trauma only to reappear within a few seconds. This confirms that it was sweating of blood and not bleeding. Bleeding time, clotting time and prothrombin time was normal. Patient was diagnosed with hematohidrosis clinically by exclusion, confirmed by benzidine test, biochemical and microscopic examination of fluid. At present, no treatment is available for this condition. Etiology is unknown till date. Stress may be a precipitating factor.
