Priapism in a patient with unstable hemoglobin: Hemoglobin Köln

We report a case of severe priapism occurring in a patient with unstable hemoglobin, hemoglobin Koln, and underline several factors that may have contributed to this complication: abnormal plasticity of red cells, splenectomy, and cytomegalovirus infection. Since emergency treatment may prevent impotence, patients and parents should be educated about this complication. Am. J. Hematol. 74:73–74, 2003. © 2003 Wiley-Liss, Inc.
