Hematidrosis is a disorder in which blood-tinged fluid exudes from uninjured skin or mucosa. It is often classified as an eccrine sweat disorder, though the precise mechanism—including involvement of sweat glands—has yet to be proven. In contemporary case reports, hematidrosis appears most frequently in the pediatric population, with 83% of cases in the literature since 2008 occurring in individuals 18 years old or younger. We present here a case of a 10-year-old girl with hematidrosis followed by a review of the literature, with an emphasis on the features of this condition in the pediatric population.
