[Splenectomy as definitive surgical treatment for hemophagocytic lymphohistiocytosis].

Background: Hemophagocytic syndrome or hemophagocytic lymphohistiocytosis (HL) is an immune hyperactivation of multifactorial etiology, characterized by excessive activation of lymphocytes and macrophages, as well as numerous pro-inflammatory cytokines. It has a non-specific and highly variable clinical presentation, with splenomegaly being one of the clinical manifestations. Due to its nature, it can manifest during childhood or adult life, which is why it is a disease of diagnostic and therapeutic complexity.
Clinical Case: 38-year-old male patient without comorbidities, who presented with abdominal pain, choluria, fever > 38 °C and diaphoresis of more than 10 days of evolution. A bone marrow aspirate was performed as part of the diagnostic approach with data compatible with hemophagocytosis and cytopenias. The immunosuppressive management did not show the expected response, which is why an open splenectomy was performed as the last therapeutic option with adequate hematological control. A documentary review of the disease was carried out, and of the therapeutic options, emphasizing surgical management in case of refractoriness to medical treatment.
Conclusions: Splenectomy increases the overall survival rate and the time free of HL progression, even though there are still no studies to determine with certainty the ideal time to perform a splenectomy in patients with pancytopenia without splenomegaly who suffer from hemophagocytic syndrome.
