INTRODUCTION: Systemic lupus erythematosus (SLE) is autoimmune disease with variable symptoms. While dermatologic manifestations and coagulopathies are common in SLE, we encountered a case with a unique initial presentation.
CASE PRESENTATION: 65-year-old female with medical history of diabetes, chronic kidney disease, hypertension treated with hydralazine, and gastric sleeve surgery initially presented with petechial rash, fatigue, and pancytopenia with unremarkable bone marrow. She was later admitted with generalized hemorrhagic bullae, spontaneous spinal intradural hematoma requiring evacuation, acute kidney injury requiring dialysis, and anemia requiring transfusions. An episode of hematemesis prompted intubation. She was transferred to our facility intubated and on corticosteroids due to positive antinuclear antibody (ANA). Physical exam only revealed generalized hemorrhagic blisters and oral ulcers. Laboratory tests showed pancytopenia, activated partial thromboplastin time 68.3s, prothrombin time 20.8s, fibrinogen 131mg/dL, positive fibrin monomers, low coagulation factors, elevated antibodies (ANA, ds-DNA antibodies, anti-histone antibodies, lupus anticoagulant, c-anti-neutrophil cytoplasmic antibody, myeloperoxidase), and low complement. She was diagnosed with disseminated intravascular coagulation (DIC) and SLE. Skin biopsy was negative for vasculitis or specific dermatosis. Her bullae improved with steroids, but she developed diffuse gastrointestinal bleed not amenable to endoscopic therapy, requiring daily transfusions. Plasmapheresis and cyclosporine were initiated, but bleeding persisted and renal function worsened. Her family decided to withdraw life support.
DISCUSSION: DIC in SLE is rare, with one review reporting only 24 cases in the literature. The pathogenesis is not clear and may be related to vasculitis or anti-phospholipid antibodies. Skin involvement occurs in 75%, but bullous lesions are uncommon. Blisters may form due to vacuolar degeneration of epidermal basal layer or antibodies against collagen VII. There have been cases of spinal epidural hemorrhage reported in SLE. This is the first case of spontaneous intradural hematoma in SLE to the best of our knowledge.
CONCLUSIONS: Our case has a very unusual constellation of SLE manifestations. DIC and bullous lesions are rarely seen in SLE and no cases of spontaneous spinal intradural hematoma have been reported.
