Late relapsing childhood lymphoblastic leukemia.

Childhood lymphoblastic leukemia (ALL) is usually assumed to have been permanently eradicated in patients in long-term remission, but occasionally can recur after many years. To learn more about the problem, we studied a group of children whose leukemia had been in remission for 10 or more years before relapse and tried to determine whether they had true recurrences or second malignancies. We studied children treated on Medical Research Council ALL protocols between 1970 and 1984 and followed up by the Clinical Trial Service Unit in Oxford.

We report a case of humero-spinal dysostosis which is only the fourth reported in the literature. The condition is characterized by distal bifurcation of humeri, elbow joint dislocation, spinal malformation, widened iliac bones and talipes equinovarus.
