MYELOBLASTOSE AIGUE AU COURS DU SYNDROME DE VON JACKSCH-LUZET

A 7 month-old infant of Italian origin, who was given a vitamin D deficient diet developed a Von Jacksch-Luzet syndrome with more than 20% myeloblasts in the bone marrow. Plasma levels of vitamin D metabolites were low and parathormone levels were high. A low dose of vitamin D3 (2,000 IU cholecalciferol/day) resulted in the recovery of a normal phosphocalcic balance and in the disappearance of myeloblastosis.
