Epithelial Membrane Antigen Immunohistochemistry Biopsy Tissue
What is this test?
Epithelial membrane antigen (EMA) is expressed by epithelial cells of all types, mesothelial cells, perineural cells, and a subset of plasma cells. EMA is expressed by meningiomas, synovial sarcoma, epithelioid sarcoma, a subset of peripheral nerve sheath tumors, the lymphocyte-predominant cells of lymphocyte-predominant Hodgkin lymphoma, and anaplastic large cell lymphoma. Diagnostically, EMA is useful in recognizing epithelial derivation of poorly differentiated malignant tumors. The following CD markers are expressed on specific hemotologic cells. Individual and a series of IHC markers can be run on unknown cells and presence or absence of the antigen can help to characterize the cell of interest.
Also known as IHC Marker EMA Immunohistochemistry Biopsy Tissue.
