Psychogenic Purpura (Gardner-Diamond syndrome, autoerythrocyte sensitization syndrome, painful bruising syndrome)
Psychogenic Purpura also known as Gardner-Diamond syndrome, autoerythrocyte sensitization syndrome, painful bruising syndrome. 287.2 (Other nonthrombocytopenic purpuras)
Are You Confident of the Diagnosis?
Rule out factitious, malingering, and abuse.
What you should be alert for in the history
Be alert for predictable bruising associated with psychological stress in the absence of a hematologic, vascular, immunologic, or infectious process.
Characteristic findings on physical examination
Characteristic findings include unexplained painful, ecchymotic lesions, mostly on the extremities and the face. Initial symptoms include burning and pain followed by erythema, edema, pruritus, and eventually ecchymoses. Lesions may be accompanied by systemic symptoms; gastrointestinal, rheumatologic, neurologic. Lesions are often precipitated by emotional stress, and may occur after surgery or trauma. Patients often present with a psychiatric comorbidity.
Expected results of diagnostic studies
Hematologic and coagulation studies are normal. Obtain a complete blood count (CBC) with differential, platelet count, platelet function analyzer (PFA-100), antiphospholipid antibodies, von Willebrand’s panel, antinuclear antibody (ANA), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) to rule out other organic etiology. The autoerythrocyte sensitization test (0.1ml intradermal injection of washed autologous erythrocytes) is unreliable and generally not useful.
It is important to rule out coagulopathy, vasculitis, von Willebrand’sdisease, Ehlers-Danlos, hereditary hemorrhagic telangiectasia,Henoch-Schönlein purpura, vitamin C deficiency, antiphospholipidsyndrome, medications (acetylsalicylic acid, nonsteroidal antiinflammatory drugs, glucocorticoids, possibly selective serotonin reuptake inhibitors (SSRIs),and illicit drugs.
Who is at Risk for Developing this Disease?
Middle-aged Caucasian females with psychiatric comorbidity appear at greatest risk. Pediatric and male cases have been reported.
What is the Cause of the Disease?
The etiology is unclear. Stress and psychiatric disorders frequently are present; possibly etiologic.
Postulated mechanisms include a stress-induced increase in endogenous glucocorticoids, causing altered hemostasis, increased fibrinolysis secondary to increased activity of tissue plasminogen activator, and autoerythrocyte sensitization (autosensitization to phosphoglyceride on the RBC membrane). Malingering, factitious disorders are possible; but one must must first rule out organic etiologies. Rule out relationship abuse.
Systemic Implications and Complications
Affected patients tend to have many associated somatic complaints and psychiatric comorbidities. No clear link established between disorder itself and other pathologic biologic entities.
No controlled studies exist. Treatment should be directed toward lesion control, pain control, and intervention for an underlying or associated psychiatric disorder. Psychotherapy should be suggested as the most effective intervention.
Medical treatment includes:
Bland topicals; ie, petrolatum or Aquaphor, for open lesions.
Topical lidocaine 2-5% cream or gel, topical Doxepin 5% cream for pain control.
Amitryptyline 10-50mg at night or twice daily dosing for pain control.
Consider gabapentin 100mg three times a day, titrating to 300mg three times a day, for pain control.
SSRIs and selective norepinephrine reuptake inhibitors (SNRIs) may help associated obsessive-compulsive disorder (OCD) and depressive symptoms. Caution is warranted since there are scattered case reports of bruising with SSRI’s. There are anecdotal suggestions for use of of beta blockers, on the grounds of their efficacy for migraine headaches and reflex sympathetic dystrophy.
Strongly recommend psychotherapy. Suggest to the patient that psychotherapy can diminish the occurrence of the disease and help them deal with the capricious, painful, and cosmetically visible nature of the disease.
Optimal Therapeutic Approach for this Disease
Once confident in the diagnosis, reassure the patient that the prognosis is good. Explain that most will have remission of symptoms (except possible recurrences during stressful periods). Help the patient understand the potential etiologic role of stress as an aggravating factor. This is the rationale for psychiatric referral. Strongly suggest and help facilitate a psychiatric referral, if possible.
Introduce topical and oral agents along with psychotherapy until lesions and symptoms abate. Observe for signs of more severe psychopathology, underlying organic disease, drug use or abuse, physical or emotional abuse.
Periodically repeat a thorough review of systems and appropriate laboratory studies.
Unusual Clinical Scenarios to Consider in Patient Management
Be vigilant for purposely inflicted factitious lesions and malingering for secondary gain.
