Abstract

To study the clinicopathologic features, immunophenotype, diagnosis and differential diagnosis of Sinonasal teratocarcinosarcoma (SNTCS). The clinical findings, morphologic features and immunohistochemical markers in one case of SNTCS were studied, and the relevant literatures were reviewed. The Tumor tissue is composed of three layers, with mature and immature squamous epithelium nests, neural epithelial cells and olfactory neuroblastoma-like cells derived of ectoderm; Sarcomatoid components and bone tissue derived of mesoderm; The glandular and tubular structures part of which is adenocarcinoma and respiratory epithelium derived of endoderm; The fetal clear cell squamous epithelium is typical. In addition, diffuse large cytoplasm-with high light and cytoplasm with dark light has no obviously boundery. Immunohistochemical staining showed immune markers of different germ layers corresponding, squamous epithelium, glandular epithelium and respiratory epithelium were positive for CK and EMA, neural epithelial cells and olfactory neuroblastoma-like cells were positive for S-100, NSE and Syn, sarcomatoid area was positive for Vim, light dye area was positive for Vim, CD99 and CK, dark area was positive for NSE and GFAP. SNTCS is a ...Continue Reading

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.
