Unlabelled:
Neonates with Down's syndrome have an increased risk for congenital leukaemia, particularly acute megakaryoblastic leukaemia (FAB, M7) which most often resolves spontaneously and is called transient leukaemia. It can be observed in non-constitutional trisomy 21 infants then presenting trisomy 21 on blasts cells.
Observation:
We report a transient leukaemia with an isolated pericardial effusion in a phenotypically normal neonate. Trisomy 21 was found on blasts cells. Complete remission remains after 32 months.
Discussion:
Congenital leukaemias, with trisomy 21 on blasts cells have a good prognosis that justifies observation before using chemotherapy.

Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
