and Non-Chromaffin Tumors: A Mediastinal Germ Cell Tumor Occurring in a Young Man with Germline Mutation.

Medicina (Kaunas) 2020 Oct 25;56(11). Epub 2020 Oct 25.

Department of Experimental and Clinical Biomedical Sciences "Mario Serio", University of Florence, 50139 Florence, Italy.

Mutations in genes encoding one of the subunits of succinate dehydrogenase (SDH) are involved in pheochromocytoma (PHEO) and paraganglioma (PGL) development. Over the last few years, such mutations have also been associated with non-chromaffin tumors. However, immunohistochemistry (IHC) on the tumor tissue and a study on the loss of heterozygosity (LOH) aimed at demonstrating the pathogenic role of genes have only been employed in a few cases.

Department of Pathology and Laboratory Medicine University of Florida-Jacksonville, Jacksonville, FL.

Germ cell tumors in the mediastinum are rare and often occur in young patients but may occur in older patients. Seminoma, embryonal carcinoma, yolk sac tumor, choriocarcinoma and teratoma have distinct morphologic features with high grade nuclei. They are the primary diagnostic consideration in young males but may be lower on the list in older patients, where they may be misdiagnosed as carcinomas. Read More

Primary Mediastinal Seminoma Achieved by Transbronchial Mediastinal Cryobiopsy.

Respiration 2020;99(5):426-430. Epub 2020 Feb 12.

Department of Respiratory Disease, Xinqiao Hospital, Third Military Medical University, Chongqing, China,

Mediastinal biopsy is essential for the clinical diagnosis of mediastinal disease. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a well-established approach for obtaining diagnostic samples from mediastinal masses or enlarged lymph nodes which is proven to be minimally invasive and effective. However, the insufficiency of intact samples acquired might restrict the diagnostic efficacy of EBUS-TBNA for mediastinal lesions such as rare malignancy and granulomatous disorder. Read More

Asymptomatic azygos vein overflow in a young patient with primary mediastinal seminoma.

Thorac Cancer 2019 12 30;10(12):2308-2311. Epub 2019 Sep 30.

Medical Oncology, Precision Medicine Department, Università degli Studi della Campania Luigi Vanvitelli, Naples, Italy.

The azygos system is the most important pathway for decompression of the superior vena cava (SVC) when a blood flow obstruction to the right atrium is present. Thoracic and mediastinal malignancies, mainly lung cancers, are responsible for 60%-85% of superior vena cava syndrome (SVCS) cases. An uncommon origin of SVCS is primary malignant mediastinal germ cell tumor (PMMGCT) which represent 1%-4% of all mediastinal tumors and can be divided into two broad groups: seminomas and nonseminomatous germ cell tumors (NSGCTs).

Late and Rapid Relapse in Mediastinum from Testicular Germ Cell Tumor Stage I Over 13 Years after Surgery.

Case Rep Oncol 2019 May-Aug;12(2):500-505. Epub 2019 Jun 26.

Department of Central Laboratory, Shinshu University School of Medicine, Matsumoto, Japan.

Patients with stage I testicular germ cell tumors have a long life expectancy, but the tumors have a potential to relapse after treatment. Although relapse is observed within a few years in most cases, late relapse over 10 years after initial treatment has also been reported in patients with stage I testicular germ cell tumors. We encountered a case of testicular seminoma that developed mediastinal lymph node metastasis 13 years after radical surgery for the primary tumor. Read More

J Clin Pathol 2019 Aug 4;72(8):536-541. Epub 2019 May 4.

Department of Medicine and Surgery, University Milan Bicocca, Milan, Italy

Aims: Very recent papers proposed a possible role for the expression of terminal deoxynucleotidyl transferase (TdT) in the tumourigenesis of gonadal and extragonadal germ cell-derived tumours (GCTs). Our multicentric study evaluated the magnitude of the immunoreactivity for TdT in GCTs, encompassing seminoma, dysgerminoma, mature teratoma and mixed GCTs.

Methods And Results: The histological series was stained with both monoclonal and polyclonal antibodies, yielding a positivity of 80% of cases with well-defined nuclear reactivity. Read More
