title: [Scrotal space-occupying lesions].
abstract: Palpable scrotal masses are common scenarios in any clinical practice. These tumors can be painful or painless, can be intratesticular or extratesticular and be cystic or solid. The distinction between benign and malignant tumors is of utmost importance to enable an adequate and differentiated therapy of patients. In clinical diagnostics besides the medical history, examination of the inguinoscrotal region, laboratory diagnostics and ultrasound examination of the inguinoscrotal area play a decisive role. During the last few years the increased use of contrast-enhanced ultrasound has helped clinicians in differentiating scrotal tumors. Malignant tumors are of particular importance because this entity is the most frequent malignant disease among younger men and according to the Robert Koch Institute there are approximately 3900 new patients in Germany each year (Robert Koch Institute, Krebs in Deutschland 2007/2008 and 2012).
