Diamond-Blackfan anemia (DBA) is a rare congenital erythroid hypoplasia. An association with very early onset inflammatory bowel disease (VEO-IBD) has only been reported a few times. We report a Caucasian boy with a transfusion-dependent DBA phenotype from birth and severe ulcerative pancolitis from 10 months of age. He underwent successful allogeneic hematopoietic stem cell transplantation (HSCT) at 2 years of age. On follow-up 8 years old, he had normal bone marrow function and no bowel symptoms. HSCT was curative for both DBA and VEO-IBD. The underlying course of DBA and pancolitis remains elusive.
