TESTICULAR NECROSIS ASSOCIATED WITH PARAPR OTEINEMIA

Abstract

Pathogenesis of testicular necrosis has been reported to be torsion of spermatic cord or obliterating thromboangitis of spermatic vessels, although there have been some cases referred to as idiopathic.
The case of testicular necrosis presented here revealed paraproteinemia secondary to extramedullary plasmacytoma, which was confirmed by chest X-ray and scalenus lymph node biopsy. It is likely that paraproteinemia caused disturbances of circulation and coagulation which resulted in thrombosis formation of spermatic vessels and necrosis of testis and epididymis.
It is possible that in some diseases testicular necrosis appears as the initial symptom before the underlying primary disorder is disclosed. In such a case, the cause of testicular necrosis is usually reported as idiopathic. However, the authors assume that there is a possibility that, in this idiopathic group, there are some cases of paraproteinemia as we reported in this paper.
