The Zemblanity of Missing Subtile Changes in the Patient'S Blood Tests-Diagnosing Hereditary Spherocytosis After Finding Extramedullary Haematopoiesis

Abstract

We report a clinical case of hereditary spherocytosis in the view of it´s educational value. The diagnose was overlooked for many years while the patient was a regular blood donor. This was probably the stress factor that precipitated the development of extramedullary haematopoiesis in a patient that otherwise had a rather mild phenotype. The authors want to stress the importance of valuing the red cell indexes as an informative part of the hemogram.
