Vimentin-positive and Alpha-fetoprotein-elevated Nuclear Protein of the Testis Midline Carcinoma: A Case Report and Review of the Literature.

Intern Med 2021 May 29. Epub 2021 May 29.

Department of Clinical Oncology, Yamagata University Faculty of Medicine, Japan.

Nuclear protein of the testis (NUT) midline carcinoma (NMC) is a rare malignant tumor expressing NUT with BRD4/3 rearrangements and is sometimes misdiagnosed as germinoma, especially in alpha-fetoprotein (AFP)-elevated cases. A 28-year-old man had a mediastinal tumor with multiple bone metastases and elevated AFP levels. Imaging/laboratory findings led to a pathological diagnosis of extragonadal germinoma. Read More

Sarcoid-like reaction: a unique response to immunotherapy in malignant melanoma.

BMJ Case Rep 2021 May 28;14(5). Epub 2021 May 28.

Oncology, Sligo University Hospital, Sligo, Ireland.

In recent years, immunotherapy has revolutionised the treatment landscape for oncology patients with improved survival rates in cancers which previously had a dismissal prognosis. These agents target specific pathways of inhibition such as programmed cell death -1 (PD-1), PD ligand-1 and cytotoxic T-lymphocyte-associated antigen 4 resulting in stimulation of T cell activity. This results in enabling an individual's own immune system to fight against cancer, a different modality of treatment when compared with traditional chemotherapy. Read More

Co-existent Epicardial Paraganglioma and Anterior Mediastinal Thymoma.

J Radiol Case Rep 2020 Oct 31;14(10):16-30. Epub 2020 Oct 31.

Department of Cardiovascular/Thoracic Surgery, Mayo Clinic, Jacksonville, FL, USA.

Thymoma and paraganglioma are known causes of mediastinal masses, the latter being extremely rare. Thymomas arise from remnant thymic tissue in the anterior mediastinum; whereas, thoracic paragangliomas arise from para-aortic or para-vertebral sympathetic chain ganglion (derivatives of embryonic neural crest) in the middle or posterior mediastinum. We report a case of a middle-aged woman with two mediastinal masses, originally believed to be a single tumor or primary malignancy with adjacent metastasis on Computed Tomography (CT) that were further delineated with Magnetic Resonance Imaging (MRI) and [68Ga]-DOTA-(Tyr3)-octreotate (DOTA-TATE) Positron Emission Tomography-Computed Tomography (PET-CT) and surgical pathology as two distinct entities: left epicardial paraganglioma and anterior mediastinal thymoma.

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.
