Malignant mesothelioma of tunica vaginalis testis

Malignant mesothelioma of the tunica vaginalis Testis: Unusual sonographic appearance

“…3 A positive history of asbestos exposure has been found in 34% of patients with mesothelioma of the tunica vaginalis. 3 The sonographic features of scrotal mesothelioma that have been reported include multiple nonhomogeneous nodular masses attached to the parietal vaginal layer 4 ; focal thickening of the tunica vaginalis testis with presence of nodularities 5 ; multiple extratesticular nodular masses of increased echogenicity arising from the scrotal wall 2 ; and well-organized soft tissue fronds of mixed echogenicity (a hypoechoic center surrounded by a hyperechoic rim) within a hydrocele. 6 Our present case differs from previous reports in that the tumor included a large cystic component, mimicking an epididymal cystic lesion.…”

“…Because the tunica vaginalis is a layer of reflected peritoneum, mesothelioma can occur in the scrotal pouch. 2 Mesothelioma usually occurs in patients older than 45 years of age, with the highest incidence during the fifth to seventh decades of life. 3 A positive history of asbestos exposure has been found in 34% of patients with mesothelioma of the tunica vaginalis.…”

Malignant mesothelioma of the tunica vaginalis testis

“…In accordance with others, radical orchiectomy via an inguinal incision should be the first-line therapy. 5,9,44 Because mesotheliomas of the tunica vaginalis were mostly found intraoperatively or at final pathology, as in our case, incomplete resection of the tunica vaginalis was commonly reported as the primary therapy. A radical approach could not have been taken due to the lack of informed consent by the patients.…”

“…However, cytoanalysis was only performed in 9 of 74 cases, with a negative result in 7 cases, including the current case. 5,7,13,24,37,44 The majority of malignant mesotheliomas of the tunica vaginalis have been determined intraoperatively (97.3%) due to hemorrhagic hydrocele fluid, white-to-yellowish papillary excrescences of the tunica vaginalis, or fibrotic thickening of the tunica vaginalis. Data concerning the first-line surgical approach for patients with malignant mesothelioma of the tunica vaginalis were available in 62 cases (83.8%).…”

Rare Tumors of the Testis and Paratesticular Tissues

“…The hydrocele fluid is often clear but can be bloodstained and the tumor is seen as a papillary structure or nodules 154,155 standing out from the clear smooth lining of the sac.
