WAS is a severe X-linked recessive disorder characterized by microthrombocytopenia, eczema, and immunodeficiency. A six-yr-old boy with WAS diagnosed as B-cell NHL (Stage III) localized in the liver who underwent successful HSCT from HLA-one antigen mismatch sibling donor has been presented here. His conditioning regimen included ATG, busulfan, and fludarabine. He received 2.3 × 106/kg CD 34(+) stem cells and 11 × 108/kg nucleated cells at day 0. Neutrophil engraftment was achieved at day +14 and platelet engraftment at day +20. He has been in CR for more than two yr after transplantation. Thus, HSCT is an effective treatment for children with WAS even after development of lymphoma. © 2013 John Wiley & Sons A/S.
