Background: Antiphospholipid antibody syndrome is characterized by venous and/or arterial thrombosis, and is found in patients with systemic lupus erythematosus. Its diagnosis requires the presence of both clinical and laboratory findings, such as positive anti-cardiolipin and anti-β2 glycoprotein I antibodies and lupus anticoagulant. However, cardiolipin is a minor component of the vascular endothelial cells in human, and phosphatidylcholine and phosphatidylethanolamine are major components.Case presentation: A 15-year-old female suddenly developed massive left intraretinal hemorrhaging due to central retinal vein occlusion. She also had a butterfly rash, and her laboratory findings revealed positive serum anti-nuclear antibodies and decreased serum complement. During this episode, she was diagnosed with systemic lupus erythematosus. Although she was negative for serum anti-cardiolipin IgG and anti-β2 glycoprotein I antibodies as well as lupus anticoagulant, her serum anti-phosphatidylcholine, anti-phosphatidylethanolamine, anti-phosphatidylinositol and phosphatidylserine IgG antibodies levels were increased.Conclusion: Pediatric cases of central retinal vein occlusion are rare. Even in patients without anti-cardiolipin or anti-β2 glycoprotein I antibodies and lupus anticoagulant, there is the potential for the development of antiphospholipid antibody-related thrombosis. © 2014 Korematsu et al.; licensee BioMed Central Ltd.
