A RARE CASE REPORT ON PARATESTICULAR MALIGNANT MESOTHELIOMA

Paratesticular mesotheliomas are rare tumours. The sole plausible causative factor so far ascertained in the pathogenesis of these tumors is asbestos, which however is found in only around 30 to 40 of such cases. The age range of affected individuals is wide, mostly adults and the elderly, but also includes young people and children.Malignant mesothelioma is an uncommon tumour arising in body cavities lined by mesothelium. The majority of these tumours are found in the pleura, peritoneum and less frequently pericardium. As the tunica vaginalis is a layer of reflected peritoneum, mesothelioma can occur in the scrotal sac. The nonspecific symptoms, broad age distribution and lack of tumour markers make pre-operative diagnosis of malignant mesothelioma of the tunica vaginalis difficult and indeed most of the reported cases were diagnosed at histology.
