Hematohidrosis induced by separation anxiety disorder during COVID-19 quarantine: a case report and brief literature review

Abstract

Here, we report a case involving a 10-year-old Vietnamese girl who developed hematohidrosis during the coronavirus disease quarantine. She was hospitalized with a 3-week recurrent bleeding on the abdominal skin. Physical examination revealed no signs of injuries on the skin. Hematological and biochemical test results and coagulation profiles were all within normal ranges. No abnormal findings were observed on abdominal ultrasonography and computed tomography. Numerous erythrocytes were observed during the microscopic examination of fluid samples from the abdominal skin. It was speculated that hematohidrosis was precipitated by separation anxiety disorder, because the onset and remission of symptoms correlated with the beginning and end of the local quarantine, respectively. Our case report and brief literature review highlight the transient and benign nature of hematohidrosis. Although specific guidelines are not well established, hematohidrosis is a transient phenomenon that is treatable with pharmaceutical and non-pharmaceutical interventions, and its overall prognosis is favorable.
