Henoch-Schönlein purpura and priapism.

This is the first report of priapism in a child with Henoch-Schönlein purpura. Priapism is a condition rarely seen in childhood. When seen in the paediatric population, it is most often associated with haematological disorders. On a world-wide basis, sickle cell anaemia accounts for the majority of childhood priapism. Failure to treat priapism can lead to serious sequelae, including fibrosis and impotence.
