title: [Renal extramedullary hematopoietic tumor revealing a hereditary spherocytosis in an adult patient].
abstract: BACKGROUND
  Myelolipomas and extramedullary hematopoietic tumors are uncommon benign tumors. They are variably composed of mature adipose tissue and hematopoietic tissue. Myelolipoma is usually observed in the adrenal gland and extramedullary hematopoietic tumors in the liver and spleen but may occasionally be found within solid tumors.
  
  
  METHODS
  A 62-year-old man without previous haematological history presented with a voluminous solitary bilateral renal tumor. Contrast-enhanced ultrasound CT-scan and scintigraphy with technetium-99m-nanocolloid and indium-111-chloride bone marrow were highly suggestive of extramedullary hematopoietic tumor. CT-guided biopsy suggested a diagnosis of myelolipoma. An atypical hereditary spherocytosis, undiagnosed until now, was demonstrated.
  
  
  CONCLUSIONS
  We report, for the first time to our knowledge, a border form between extramedullary hematopoiesis tumor and myelolipoma of renal localisation revealing a hereditary spherocytosis in an adult patient.
