Orchitis mimicking testicular torsion in Henoch-Schönlein's purpura.

Henoch-Schönlein's purpura is a systemic vasculitis involving mainly skin, joints, intestine and kidney. We report on 2 patients who presented with clinical signs and symptoms suggestive of testicular torsion. In 1 case purpuric areas after leg cast removal indicated a diagnosis of Henoch-Schölein's purpura. Surgical exploration of the other case revealed congestion of the hydatid of Morgagni, which was followed by typical systemic manifestations of Henoch-Schönlein's purpura. These and another case indicate that orchitis accompanying Henoch-Schönlein's purpura may mimic testicular torsion.
