ABSTRACT
Malignant mesotheliomas are rare entities (0.1-0.2% of all malignant tumors) possibly localized at the pleura, peritoneum, pericardium, and tunica vaginalis. Most malignant mesotheliomas are caused by asbestos inhalation. We report on a man who suffered from malignant mesotheliomas of the tunica vaginalis and of the pleura simultaneously. The development of these tumors was probably multicentric; the patient had been exposed to asbestos over a period of 22 years. We discuss the individual findings and the current literature.

A markedly increased incidence of cancer in renal transplant recipients is now recognized; to determine if immunosuppression alone may be responsible for this increase in risk, cancer incidence was compared in 709 renal transplant recipients and 317 dialysis patients. Malignancy developed in 19 transplant recipients (2.7%) and in 33 patients on chronic dialysis (10.4%). In our report an excess of skin cancer was observed in the transplant series while tumors of the urinary tract were seen more frequently in patients on dialysis. Transplantation and consecutive immunosuppression does not appear to constitute an additional cancer risk for the uremic patient who is faced with the alternative to undergo chronic dialysis or renal transplantation.
