[Malignant mesothelioma of the tunica vaginalis].

Case report of a new case of malignant mesothelioma of the tunica vaginalis testis. A mediterranean male age 62, presented with enlargement and swelling of the scrotum, treated as orchiepydidymitis within the previous 3 months. Physical and ultrasonography examination showed a left scrotal mass with extension to the skin of the scrotum. After surgery (orchiectomy and partial hemiscrotectomy) and histopathology diagnosis of locally advanced malignant mesothelioma, CT showed metastasis in retroperitoneum, Lung and Liver. The patient undergoes chemotherapy and radiotheraphy with a poor prognose. We review the diagnosis, histopathology and therapeutical approach for this uncommon kind of paratesticular tumor (less than 80 cases reported in the last 30 years).
