title: Malignant mesothelioma of the tunica vaginalis testis.
abstract: Eighteen patients with malignant mesothelioma of the tunica vaginalis testis have been previously reported. These and the six patients reported here are reviewed for natural history and response to treatment. This tumor should be considered in men of any age with scrotal masses that include a hydrocele. Staging procedures should include computerized tomography scanning of the chest and abdomen. Inguinal orchiectomy appears to be the optimal primary surgical approach. Intraabdominal disease found at diagnostic laparotomy may be effectively treated by surgery and/or abdominal radiotherapy. Clinical features such as a long asymptomatic interval from initial presentation to clinical recurrence were observed and are also worthy of emphasis. Thus, serial follow-up is advised. Upon recurrence, treatment remains unsatisfactory but some responsiveness to chemotherapy has been noted. Doxorubicin-containing regimens were administered to five patients with measurable pulmonary nodules resulting in two partial regressions by standard criteria.
