CORRECT DIAGNOSIS:

Gardner-Diamond Syndrome

DISCUSSION:

Gardner Diamond Syndrome, also known as psychogenic purpura or autoerythrocyte sensitization, is a rare disorder characterized by the spontaneous or induced development of painful purpuric lesions. First described by Gardner and Diamond in 1955, this syndrome has been the subject of various studies and discussions due to its unique presentation and complex etiology.

The term “autoerythrocyte sensitization” derives from the observation that some patients react to intradermal injections of their own erythrocytes. This reaction suggests the possible presence of autoantibodies against phosphatidylserine, a phospholipid component of erythrocyte membranes. However, it is important to note that this reaction is not universally present among patients, which limits its utility as a definitive diagnostic criterion. The initial cases documented by Gardner and Diamond highlighted the rapid progression of edematous and erythematous lesions following trauma, ultimately leading to painful purpura.

Typically affecting young females, Gardner Diamond Syndrome is characterized by the spontaneous or induced development of painful, edematous, atypical purpuric lesions that vary in size. These lesions are most commonly seen on the lower legs, although involvement of other sites has been documented. One of the hallmark features of this syndrome is the resolution of lesions within a two-week period, followed by a tendency for recurrence. In addition to skin manifestations, patients often report a range of associated symptoms, including abdominal pain, nausea, vomiting, diarrhea, and headaches.

The exact etiology of Gardner Diamond Syndrome remains unclear, although several associations have been reported. Underlying psychiatric conditions, such as anxiety, depression, borderline personality disorder, and difficulties in managing aggression and hostility, are frequently noted among affected individuals. Furthermore, a preceding traumatic event—such as a medical procedure or surgery occurring up to two years before the onset of symptoms—may trigger the syndrome. Severe psychosocial stressors, including marital conflicts or the illness or death of a family member, have also been implicated.

Diagnosing Gardner Diamond Syndrome involves a thorough laboratory workup to exclude potential hematologic or autoimmune causes. Essential tests include a complete blood count (CBC) with platelet count, peripheral blood smear, prothrombin time, and partial thromboplastin time. Skin biopsy typically reveals extravasated red blood cells without key features suggesting vasculitis. Consequently, the diagnosis is primarily clinical, relying on characteristic presentation and the exclusion of other precipitating factors—be they hematologic, vascular, immunologic, or infectious in nature.

TREATMENT:

CONCLUSION:

Gardner Diamond Syndrome, also known as psychogenic purpura or autoerythrocyte sensitization, is a rare disorder characterized by spontaneous or induced painful purpuric lesions, primarily affecting young females. First described by Gardner and Diamond in 1955, the condition often follows trauma and is associated with underlying psychiatric issues, traumatic events, and psychosocial stress.

Our patient, a 30-year-old female, has experienced these painful lesions and has sought treatment from various specialists. Despite undergoing pain management, she discontinued those visits due to a lack of improvement. Currently, she is seeing a psychiatrist and has recently started selective serotonin reuptake inhibitors (SSRIs). A nerve study is pending with neurosurgery to further evaluate her condition.

Management of Gardner Diamond Syndrome remains challenging, emphasizing the need for long-term treatment of psychiatric conditions through psychotherapy and SSRIs. While antihistamines may provide some symptomatic relief, corticosteroids and immunosuppressive agents have shown little effectiveness. A comprehensive approach is essential for optimizing patient outcomes.
