Abstract

Objectives: Because of limited reported cases, it is unknown how often testicular vasculitis represents isolated or systemic disease. Methods: We report 19 cases (15 consultation; 4 in-house cases) of localized testcular infarction with associated vasculitis spanning 24 years. Results: All were orchiectomy specimens; detailed clinical information was available in 16 cases. Mean age was 38 years. Clinical presentation was testicular pain in 13 and mass in 3 patients. Preoperative impression was testicular cancer in 13 cases. In all cases, localized testicular infarction associated with vasculitis was present and in none was tumor identified. Most cases (n = 14) showed polyarteritis nodosa (PAN)-like features with transmural necrotizing inflammation of small-medium arteries. In 4 cases, vasculitis was granulomatous (2 necrotizing; 2 non-necrotizing) and in 1 case was lymphocytic. An infectious etiology was excluded clinically and by special stains. Four patients were subsequently confirmed with systemic vaculitis: one with PAN, one with Wegener vasculitis, one with vasculitis not otherwise specified and one with subclinical systemic vasculitis. Two of those 4 patients had testicular PAN-like vasculitis and 2 had granulomatous vasculitis. Conclusions: Testicular vasculitis can cause localized infarction that clinically mimics cancer. Although testicular vasculitis is an isolated finding in most patients an associated systemic vasculitis is not a rare event (4/16, or 25%), especially if the vasculitis is granulomatous (50% in this series). All patients should be clinically investigated for systemic disease.
