Lymph node dissection at the time of radical nephrectomy for high-risk clear cell renal cell carcinoma: indications and recommendations for surgical templates

TLDR: The pathologist must be aware of this condition and look for vasculitis whenever a patient with an infarcted testis has no history of torsion or trauma and all patients should be clinically investigated for systemic disease.

Abstract: Editorial Comment This is a large series of a rare condition in the testis. Testicular vasculitis can cause localized infarction that clinically may mimic cancer (1). Testicular vasculitis may be an isolated finding, however, in most patients is associated with systemic vasculitis. All patients should be clinically investigated for systemic disease. In this series of 19 cases the mean age was 38 years and most cases (n = 14) showed polyarteritis nodosa-like features with transmural necrotizing inflammation of small-medium arteries (2). The pathologist must be aware of this condition and look for vasculitis whenever a patient with an infarcted testis has no history of torsion or trauma.
