Abstract

Congenital dyserythropoietic anemias (CDAs) are a group of relatively rare inherited anemias. They are characterized by ineffective erythropoiesis and classified as three major groups and a number of variants. CDA type II, also known as hereditary erythroblastic multinuclearity with a positive acidified serum test (HEMPAS), is the most frequent one. A number of associations with CDA II have been reported, although each described only one or a few patients. Here we presented a piebald woman with vaginal atresia who was tested for anemia and diagnosed as CDA type II. Piebaldism and anemia association were previously described in the mouse. Our case was the first that shows the features of both piebaldism and CDA in the same patient. This association may suggest a stem cell defect to cause both hematopoietic and cutaneous manifestations. Am. J. Hematol. 69:210–213, 2002. © 2002 Wiley‐Liss, Inc.
