Priapism as a presentation of T-cell acute lymphoblastic leukaemia in a child.

We report a case of a child who presented to the ED with priapism. This was the initial presentation of T-cell acute lymphoblastic leukaemia (ALL). To our knowledge, this is the first report of a child with T-cell ALL presenting with priapism. This case demonstrates the importance of identifying the underlying cause of priapism, as it directly impacts on both initial and ongoing management.
