[Leukoerythroblastosis as a manifestation of disseminated neuroblastoma in childhood].

A check is made of the hematologic disorders in 20 children with neuroblastoma and its relation with the stage of the tumour. The 75% of the patients had metastasis when they are examined, 70% anemia, 15% leukopenia, 20% thrombopenia and 50% leukoerythroblastosis. The patients with leukoerythroblastosis all had remote metastasis and made up 66% of the children with IV or IV-S stage. In 50% of the patients there was metastasis in the bone marrow and 80% of these had leukoerythroblastosis.
