Characterization of testicular embryonic-type neuroectodermal tumor and embryonic-type neuroectodermal tissue admixed with mature neuro-glial tissue using a broad immunohistochemical panel
Embryonic-type neuroectodermal tumor (ENT) is a somatic-type malignancy characterized by overgrowth of embryonic-type neuroectodermal tissue (EtNT). In germ cell tumors, EtNT is frequently intermingled with other components that may exhibit significant morphologic overlap [mature neuro-glial tissue (MNGT), nephroblastomatous tissues, and primitive endodermal-type glands]. Therefore, the quantification of EtNT (crucial for the diagnosis of ENT) can be challenging. In this study, we investigated the immunohistochemical profile of ENT, EtNT, and MNGT using a broad immunohistochemical panel. We found that SOX2 was the most sensitive marker for EtNT (100%), but it also stained MNGT (28.6%). GFAP and S100 were relatively sensitive (71.4%) and highly specific (GFAP 100%, S100 85.8%) for MNGT, whereas synaptophysin stained both. Combining our results with those of previous studies, we propose that a combination of SOX11, SOX2, GFAP, S100, AFP, villin, CDX2, PAX8, and nuclear WT1 may help to identify and quantify EtNT in germ cell tumors.
期刊介绍：
Manuscripts of original studies reinforcing the evidence base of modern diagnostic pathology, using immunocytochemical, molecular and ultrastructural techniques, will be welcomed. In addition, papers on critical evaluation of diagnostic criteria but also broadsheets and guidelines with a solid evidence base will be considered. Consideration will also be given to reports of work in other fields relevant to the understanding of human pathology as well as manuscripts on the application of new methods and techniques in pathology. Submission of purely experimental articles is discouraged but manuscripts on experimental work applicable to diagnostic pathology are welcomed. Biomarker studies are welcomed but need to abide by strict rules (e.g. REMARK) of adequate sample size and relevant marker choice. Single marker studies on limited patient series without validated application will as a rule not be considered. Case reports will only be considered when they provide substantial new information with an impact on understanding disease or diagnostic practice.
