title: [Acute, painful, swollen testis in polyarteritis nodosa: a diagnostic problem].
abstract: An acutely painful and swollen testis mandates urgent diagnostic and therapeutic measures since this symptom complex may indicate torsion of the testis. Prompt scrotal exploration is necessary if the testis is to be saved from ischemic necrosis. Polyarteritis nodosa (PAN) is a vasculitis involving mainly medium and small sized arteries and may damage any organ. In PAN, the presentation of an acutely painful and swollen testis raises a perplexing diagnostic problem since the symptoms may be related to vasculitis involving the testis on the one hand, or represent primary testicular pathology unrelated to the underlying PAN. A 31-year-old man with PAN who presented with acute pain and swelling in a solitary testis is reported.
