Malignant mesothelioma of tunica vaginalis without any risk factors

Abstract

Malignant mesothelioma (MM) of the tunica vaginalis (TV) is a rare tumor. It is seen in elderly patients, with painless scrotal swelling being the most common presentation. The exact etiology is unknown; a few risk factors have been suggested. Here, we present an uncommon case of MM of TV without any known predisposing factors. We also discuss the possible risk factors, clinical presentation, pathological features and the difficulties in diagnosis, and management of this rare malignancy.

Ultrasonography of a giant adenomatoid tumor of the tunica vaginalis: A case report and review of the literature

“…Most malignant mesotheliomas in men occur between the ages of 55 and 75 years [9] ; however, adenomatoid tumors of the male genital system often occur between the ages of 30 and 50 years [10] . Currently, the only proven risk factor for malignant mesotheliomas is exposure to asbestos, but this risk factor was only confirmed in about 35% of testicular mesothelioma cases [11] . This patient was relatively young and has no history of asbestos exposure.…”
