Acute basophilic leukaemia and translocation t(X;6)(p11;q23).
We report two infants with acute basophilic leukaemia associated with a t(X;6)(p11;q23) as the sole abnormality. Morphologic evidence of basophilic lineage was provided by light and electron microscopy. Both patients also had a similar presentation on diagnosis, characterized by clinical signs consistent with a hyperhistaminaemia syndrome, i.e. urticarian rashes and gastro-intestinal disorders evocative of peptic ulcer. Immunophenotypes differed in the two patients, one expressing CD24, CD13 and CD33, whereas only CD117 was found in the other. Basophilic acute leukaemia, a rare group among acute leukaemias, might be nonrandomly associated with a specific chromosomal abnormality, t(X;6)(p11;q23). This new entity might also be identifiable by an uncommon clinical presentation and occurrence in infancy.
