Abstract summary 

Hyperreactive malarial splenomegaly syndrome (HMSS) is a rare cause of splenomegaly in the Western world. Hyperreactive malarial splenomegaly syndrome is caused by an aberrant immunological response to chronic malaria exposure in endemic areas. Revised Fakunle's criteria may be helpful for diagnosis: persistent splenomegaly (> 10 cm below the costal margin), increased anti- antibodies, increased IgM levels, exclusion of other causes of splenomegaly or malignancy, and a favorable response to antimalarial treatment. We describe the case of a 16-year-old patient, who recently arrived in Belgium from Guinea with a history of splenomegaly and B symptoms in whom HMSS diagnosis was achieved, thanks to the loop-mediated isothermal amplification method. To our knowledge, this is also the first described case treated by dihydroartemisinin/piperaquine.
