Renal extramedullary hematopoiesis simulating hypernephroma.
We report a 63-year-old woman who presented with anemia and a left kidney mass. Guided fine-needle aspiration of the mass revealed extramedullary hematopoiesis and enabled avoiding an unnecessary operation. Subsequent bone marrow biopsy demonstrated myelofibrosis. Twenty-four months later the mass remained stable.
