[Priapism associated with Fabry's disease].

We present a rare case of priapism in a child, ten years old, in association with Fabry's disease. The child had a history of disseminated nodular enlargement, crises of fever, intermittent pain in the extremities and ten hours persistent painful erection of the penis. We don't obtain pain or erection relief with sedation, epidural block and irrigation of the corporal bodies. A saphenous-cavernous shunt, in the Grayhack fashion made, being results satisfactory. In the follow-up, the child had sporadic pain in the extremities and no erection of the penis. The cavernosography showed the shunt open. Fabry's disease was confirmed by nodular biopsy and the demonstration of deficient alpha-galactosidase.
