Marinesco-Sjogren syndrome is a rare autosomal recessive disorder char
acterized by cerebellar atrophy, ataxia, cataracts, short stature and
varying degrees of mental retardation. A high incidence of malignant d
isease associated with this syndrome has not so far been reported. We
report the case of a 6-year-old girl affected with Marinesco-Sjogren s
yndrome, who developed acute myeloblastic leukemia (AML, M2), and whos
e karyotype was 46,XX,t(8;21),(q22;q22) in bone marrow blasts. This is
the first report of Marinesco-Sjogren syndrome associated with malign
ant disorders.
