[Hairy cell leukemia in a patient with type II congenital dyserythropoietic anemia]

The authors report a case of hairy cell leukemia associated with congenital dyserythropoietic anemia type II. This is the first time that the association of these two rare diseases is reported in referential literature. However, simultaneous occurrence of one hereditary and other acquired disease in a 64-year-old patient, imposed significant diagnostic problems.
