Benign cystic mesothelioma of the tunica vaginalis is a rare occurrence. It usually presents with painless gradual swelling in the scrotum. These types of benign mesotheliomas typically occur in the peritoneum and usually affect young to middle-aged patients. We present in this case an unusual case of benign cystic mesothelioma of the tunica vaginalis in a 77-year-old male patient.

conclusions primary mesenteric tumors are rare and mostly benign tumors. complete surgical excision is necessary for all tumors and follow-up is necessary after surgery for malignant fibrous histiocytoma due to recurrence. case presentation we encountered four cases of different primary mesenteric neoplasms that were operated at the gazi yasargil teaching and research hospital, department of ge...

Cystic mesotheliomas are benign neoplasms, often seen in the parietal and visceral peritoneum, omentum and pelvic organs, and are exceedingly rare in the liver. It is however important to be familiar with the radiological findings of this tumour because the signal-intensity and enhancement pattern of this tumor are unusual and not typical for any of the more frequently seen mass lesions. In our...

An immunohistochemical study of reactive pleural lesions, adenocarcinomas and mesotheliomas using carcinoembryonic antigen (CEA), cytokeratin and vimentin was carried out. All the specimens were obtained at surgery except for 11 mesotheliomas found at necropsy. Vimentin was positive in 23 of 27 mesotheliomas and negative in all the adenocarcinomas and 4 of 17 reactive mesothelial lesions. Conve...

OBJECTIVE To see the distribution of Calretinin, thrombomodulin, CK5/6 and HBME-1 markers in various subtypes of mesotheliomas and extend the published data on this topic. The positivity of adenocarcinoma specific markers (CEA and BerEP4) in malignant mesotheliomas have also been evaluated. METHODS Various markers in 173 cases of malignant mesotheliomas received over a period of 8 years were ...

We investigated apoptosis and the expression of bcl-2, mcl-1, bcl-X, and bax in histological sections from 35 malignant mesotheliomas and 21 metastatic adenocarcinomas. Moreover, the expression of bcl-2, mcl-1, bcl-X, and bax were assessed by Western blotting in nonmalignant human mesothelial cells (Met5A) and seven malignant cell lines. The apoptotic index in mesotheliomas was 1.07+/-1.14%. Pa...

Malignant mesotheliomas are aggressive, asbestos-related cancers with poor patient prognosis, typically arising in the mesothelial surfaces of tissues in pleural and peritoneal cavity. The relative unspecific symptoms of mesotheliomas, misdiagnoses, and lack of precise targeted therapies call for a more critical assessment of this disease. In the present review, we categorize commonly identifie...

Epithelial cell adhesion molecule 1 (EpCAM) is an epithelial membrane glycoprotein, often used as a surrogate pan-epithelial marker. To compare the expression patterns of EpCAM and pankeratin antibody (CKpan), gold standard detection, tissue microarrays containing 11,053 samples from 101 different tumor types were analysed by immunohistochemistry. staining was detectable in 99 (82.5%) 120 tumou...

AIM The value of immunohistochemical staining in differentiating between malignant mesothelioma and pulmonary adenocarcinoma was re-examined using newly available commercial antibodies, with the aim of increasing the sensitivity and specificity of diagnosis, and simplifying the antibody panel required. METHODS Forty one malignant mesotheliomas and 35 lung adenocarcinomas were studied. Commerc...
