<abstract xmlns="http://www.w3.org/1999/xhtml"> Hereditary spherocytosis is an inherited hemolytic anemia due to red cell membrane defects, characterised by chronic hemolysis with different severity degrees, splenomegaly and microspherocytosis on the peripheral blood film.Among the possible complications in these patients are aplastic crisis and extramedullary hematopoiesis.In this article we present the case of a 42 years old man with hereditary spherocytosis diagnosed during childhood (average haemoglobin (Hb) value of 11-12 g/dl), which presented with worsening anemia, fever, chills, bone and muscle pain. The evolution was with accentuation of anemia (Hb 4.2 g/dl), decease of reticulocyte number (Ret 0,8%) and bilirubin (indirect bilirubin 2.7 g/dl). ParvovirusB19 DNA was 100.000.000 copies/ml. A computer tomography (CT)scan was performed and showed extramedullary hematopoiesis areas situated paravertebraly in the inferior thorax and hepatosplenomegaly. The infectious episode was self-limited and improved with substitution treatment.</abstract>
