ABSTRACT
BACKGROUND: Malignant mesothelioma is a neoplasm arising in serosal membranes in the body cavities. Usual presentation of the tumor is in the pleura, peritoneum and less frequently pericardium. Paratesticular mesothelioma is the rarest known form of malignant mesothelioma with only a limited number of reported cases. CASE: A case of malignant epithelial mesothelioma of the tunica vaginalis testis was reported with presentation of hydrocele and multinodular intrascrotal masses in a 20-year old male. The patient underwent surgery for post-traumatic long-term hydrocele with perioperative discovery of multiple small exophytic structures. After histological findings of the malignant mesothelioma of tunica vaginalis testis, he underwent left-side orchiectomy, followed by inguinal and pelvic lymph node dissection. Clinical staging did not reveal distant metastases. Regular follow-up visits based on physical examinations and imaging studies are to date negative for recurrence. CONCLUSION: Literature data were reviewed, and possible risk factors for the development of the neoplasm were analysed.
