Malignant mesothelioma of the tunica vaginalis

Malignant mesothelioma of the tunica vaginalis constitutes a rare but often fatal malignancy of the male genitalia. This diagnosis should be suspected in patients exposed to asbestos and presenting with clinical symptoms of either hydrocele or inguinal hernia. Frequent inguinal lymph node involvement indicates a potential role of inguinal lymphadenectomy in the primary treatment.
