RAPID COMMUNICATION Monoclonal Nature of Transient Abnormal Myelopoiesis in Down’s Syndrome

Monoclonal nature of transient abnormal myelopoiesis in Down's syndrome.

Neonates with Down's syndrome occasionally show an excess of blasts in their peripheral blood. This disorder spontaneously resolves within several months and is called transient abnormal myelopoiesis (TAM) or transient myeloproliferative disorder. It has been uncertain whether the excess of blasts in TAM is a result of a clonal proliferation or a polyclonal reactive condition. The clonality of ...

Transient abnormal myelopoiesis accompanied by hepatic fibrosis in two infants with Down syndrome.

Prenatal Diagnosis of Transient Abnormal Myelopoiesis in a Down Syndrome Fetus

We report a case of transient abnormal myelopoiesis in a Down syndrome fetus diagnosed at 28(+3) weeks of gestation that rapidly progressed to intrauterine death 10 days later. Fetal hepatosplenomegaly with cerebral ventriculomegaly, although not specific, may be a suggestive finding of Down syndrome with transient abnormal myelopoiesis. Prompt fetal blood sampling for liver function test and c...
