Veno-occlusive disease of the liver is mostly encountered as a complication of hematopoietic stem cell transplantation with myeloablative regimens with an incidence estimated to be 13.7%. It is clinically characterized by tender hepatomegaly, jaundice, weight gain and ascites. Strong clinical suspicion and an early recognition of clinical signs are essential to establish the diagnosis and institute effective regimen. Another complication of cytotoxic drugs given for cancers, is development of busulfan-induced lung injury. A strong index of suspicion is needed for its diagnosis, especially in setting where opportunistic fungal and viral infections manifest similarly. We illustrate the clinical and autopsy finings in a 2½-year-old boy who received autologous stem-cell transplantation following resection of stage IV neuroblastoma. He subsequently developed both hepatic veno-occlusive disease and busulfan-induced lung injury. The autopsy findings are remarkable for their rarity.
