[Malignant lymphoma of the testis--an urological or nonurological disease?[].

Malignant lymphomas of the testis have a special position among the tumours of the testis. Also in such cases, in which only the testis is perceptibly diseased, nevertheless must be started from a systemic disease which is clinically not yet recognizable. These special problems demand a multidisciplinary, oncological collaboration in diagnostics and therapy. After establishment of the diagnosis and semicastration by the urologist further diagnostics and therapy should be performed by the representatives of other specialities.
