Abstract
BackgroundThe objective of this study was to describe presentation, natural history, management and long-term outcomes of patients with psychogenic purpura (PP), also known as Gardner-Diamond Syndrome. MethodsIn this retrospective study, records of patients with a diagnosis of PP seen at Mayo Clinic, Rochester from 1976 to 2016 were reviewed. Available literature regarding PP was also comparatively reviewed. ResultsSeventy-six patients with a diagnosis of PP were identified and 54/76 (71%) experienced a prodromal sensation. The Condensed MCMDM-1 bleeding score, excluding cutaneous manifestations, was <3 in 91% of patients. Laboratory tests of primary and secondary hemostasis were normal. Fifty-four percent of patients had an underlying psychiatric diagnosis. Management approaches included psychological counseling and psychiatry evaluation in 44 patients. Pharmacologic treatment for 30 patients included psychotropic agents, antihistamines, hormonal medications and anti-inflammatory agents. At a median follow-up of 5years (range 1-34),13/28 (46.4%) experienced recurrent ecchymoses and 6 continued to seek hematology follow-up at Mayo Clinic, Rochester. Our data was similar to the aggregate data from case reports in the literature. ConclusionsFor patients with unexplained recurrent ecchymosis a diagnosis of PP should be considered. Diagnosis is one of exclusion and initial evaluation should include documenting a bleeding score and obtaining laboratory tests assessing primary and secondary hemostasis. The relatively low bleeding scores together with laboratory assessments support that PP is primarily a dermal rather than a systemic bleeding diathesis. In our cohort, addressing psychological stressors was the most effective treatment; however pharmacologic therapy can be used for refractory disease.
