May 29th, 2008. Malignant mesothelioma of the tunica vaginalis testis in a petrochemical worker exposed to asbestos
Tunical mesothelioma may simulate metastatic carcinoma at routine histopathological examination. Immunohistochemistry and occupational anamnesis are helpful for the correct diagnosis, which, in turn, is important for prognosis and treatment, and in relation to legal issues when asbestos is involved in the causation of the disease.

May 21st, 2008. Malignant mesothelioma of the tunica vaginalis testis related to recent asbestos
There have been 46 cases reported in urology departments in this country of the related symptoms, but only two of these have been clearly attributable to asbestos, which may be due to the investigations being insufficient to obtain a definitive diagnosis. In addition, this symptom is often diagnosed preoperatively as hydrocele testis; it is therefore important to carry out ultrasonography when a hydrocele testis has been diagnosed.
April 24th, 2008. Serous borderline tumor of the paratestis
Ultrastructurally, the cells did not demonstrate any well-developed microvilli or secretory granules and immunohistochemical findings supported SBT of Müllerian type (ovarian epithelial type tumor), while excluding a papillary type of malignant mesothelioma. The lesion in the present case was concluded to be a testicular serous tumor of Müllerian type, similar to SBT of the ovary.

16%), Ship building (7. 5%).

March 22nd, 2008. Well-Differentiated Papillary Mesothelioma of the Tunica Vaginalis Testis: Imaging on Tc-99m Heat-Denatured Red Blood Cell Scintigraphy
The patient underwent resection and histopathology revealed a well-differentiated papillary mesothelioma. Inguinal orchidectomy was subsequently performed and the patient was free of recurrence at 18 months.
November 21st, 2007. Three cases of unusual non-germ cell tumors of the testicle
Abstract By describing 3 clinical cases of unusual testicular non germinal tumors, including an adenoma of the rete testis, an undifferenciated sex cord tumor and a mesothelioma of the tunica vaginalis, we make a literature review of the unusual testicular tumors and testicular apendix, including their incidence and management. Also and as one of our conclusions, we expose the importance of the intraoperatory biopsy in the testicular cancer surgery, because even if it is infrecuent, the presence of this rare testicular tumors, in which if they are proven to be benign, the testicular unit could be preserved and the radical orquiectomy could be avoided.
October 5th, 2007. Malignant mesothelioma of the tunica vaginalis testis: a case report and review of the literature
Despite aggressive surgical and systemic therapy the prognosis remains poor with only rare long-term survivors. We report a case of malignant mesothelioma of the tunica vaginalis in 45-years-old and review of the literature is presented.
May 1st, 2007. Malignant mesothelioma of the tunica vaginalis
Discussion: The first case of malignant mesothelioma involving the tunica vaginalis, a structure embryologically derived from a layer of reflected peritoneum known as the "processus vaginalis," was reported in 1957. Only 73 cases were reported in the literature between 1966 and 1997. In up to 41% of cases, there is a positive history of asbestos exposure. Young age and localized disease are associated with a better prognosis. Radical orchiectomy limits recurrence, which usually occurs within 2 years, but may occur up to 15 years after surgery.
February 3rd, 2007. Malignant mesothelioma of the tunica vaginalis testis
The aggressiveness and poor prognosis of this tumor require radical surgery as the primary therapy. We describe the case of a 45 year old patient, in whom an epithelioid mesothelioma was incidentally detected after hydrocelectomy.
August 1st, 2006. Malignant mesothelioma of the testes
Conclusions: Ultrasonography showing snow flurries together with cloudy hydrocele fluid and visible crystal particles and thickened testicular walls may help to identify a mesothelioma of the testicular walls. Intraoperative frozen section and a high inguinal orchiectomy is the operative method of choice.
July 19th, 2006. Mesothelioma of the tunica vaginalis testis: A rare malignancy mimicking more common inguino-scrotal masses
In the latter area they are commonly confused with much commoner benign conditions. We present three cases of mesotheliomas in the tunica vaginalis testis.
April 28th, 2006. Extrathoracic mesothelial proliferations and their mimics
This is particularly true in peritoneal and testicular mesothelial tumors, in which common embryologic origin with epithelial elements results in overlapping immunohistochemistry and morphology. The particularities of peritoneal and testicular mesothelial proliferations, and the main tumors that may mimic them in these sites, as well as the value and limitations of immunohistochemistry and electron microscopy in their differential diagnosis are the subject of this review.
February 8th, 2006. Peculiar features of mesothelioma occurrence as related to exposure patterns and circumstances in the Lombard Region, Italy
Conclusions: The high proportion of cases with unknown exposure underlines the need to explore new tools and sources to ascertain asbestos exposure. An ad hoc survey in textile industries showed exposure to asbestos to be widely spread in this industry.
January 19th, 2006. Well-differentiated papillary mesothelioma occurring in the tunica vaginalis of the testis with contralateral atypical mesothelial hyperplasia
In addition, rare cases of WDPM have progressed to malignant mesothelioma, leading to its classification as a tumor of low malignant potential. Here, we report a case of multifocal WDPM occurring in the tunica vaginalis and tunica albuginea, with contralateral atypical mesothelial hyperplasia, a potentially premalignant lesion.
January 5th, 2006. Paratesticular papillary mesothelioma: a case with borderline features
This combination of benign and semimalignant characteristics can make the diagnosis of such a lesion problematic. We think that a diagnosis of "borderline papillary mesothelioma" can be considered for similar mesothelial proliferations to allow for a possible increase in diagnostic accuracy and provide an enhanced informational platform from which patients and clinicians can benefit.
December 7th, 2005. The Immunohistochemical Profile of Malignant Mesotheliomas of the Tunica Vaginalis: A Study of 20 Cases
Focal weak positivity may be encountered with BerEp4. However, histopathologists should be aware of the variability in CK5-6 staining in testicular specimens when compared with pleural mesotheliomas.
December 6th, 2005. Nonpleural mesotheliomas: mesothelioma of the peritoneum, tunica vaginalis, and pericardium
Mesotheliomas that involve the pericardium or originate from the tunica vaginalis are rare tumors. Given the rarity of these tumors, it is difficult to obtain precise information regarding their incidence, natural history, and optimal management.
November 25th, 2005. Clear cell mesothelioma of the testis with deciduoid areas–a case report
Awareness of this variant is required to avoid misdiagnosis and treatment as either metastasis from a renal cell carcinoma or as a germ cell tumor. A diagnosis of mesothelioma must be ruled out in elderly patients with epithelial-looking tumor especially if the serum germ cell tumor markers are within normal range.
October 20th, 2005. Malignant mesothelioma of the tunica vaginalis Testis: Unusual sonographic appearance
It is similar to malignant mesothelioma of the peritoneum, usually associated with asbestos exposure. We present an unusual case in which the tumor was a mix of a hypoechoic solid nodule and a cystic component with low-level internal echoes.
July 22nd, 2005. Malignant Mesothelioma of the Tunica Vaginalis
Conclusions: Malignant mesothelioma of the tunica vaginalis constitutes a rare but often fatal malignancy of the male genitalia. This diagnosis should be suspected in patients exposed to asbestos and presenting with clinical symptoms of either hydrocele or inguinal hernia. Frequent inguinal lymph node involvement indicates a potential role of inguinal lymphadenectomy in the primary treatment.
