Acute undifferentiated leukaemia in a patient of aplastic anaemia treated with foetal liver infusions.

A 54 year old man with aplastic anaemia was treated initially with androgens, corticosteroids and blood transfusions for 24 months. Subsequently, foetal liver infusions were administered thrice, with transient response after the first two infusions and maintained remission after the third. However, 32 months after the first infusion (56 month from initial symptoms), the patient developed acute undifferentiated leukaemia.
