title: Septo-optic dysplasia and hemophagocytic lymphohistiocytosis in an infant.
abstract: Macrophage activation in hemophagocytic lymphohistiocytosis (HLH) leads to severe inflammation resulting in cytopenias and multi-organ dysfunction. Septo-optic dysplasia (SOD) is an as-yet unaffiliated disorder that manifests with optic, hepatic, endocrine and/or constitutional defects. We detail the first reported occurrence of both HLH and SOD in one patient. This two-month old patient presented with acute hepatitis, direct hyperbilirubinemia, anemia and thrombocytopenia. Treatment followed standard of care practices for SOD and HLH. The patient subsequently underwent an allogeneic bone marrow transplant within eight months of diagnosis and remained in full remission at day +90. We suggest considering a diagnosis of HLH in patients with SOD who present with severe liver failure refractory to standard therapy.
