Abstract

Epithelioid trophoblastic tumor (ETT) is a rare form of trophoblastic disease, which is characterized by high malignancy and a number of diagnostic features: a long interval between the last pregnancy and labor and the onset of the disease; a visual pattern at gynecological examination, relatively low β-chorionic gonadotropin (CG) levels, as well as the diffuse expression of cytokeratins-7 (+++) and -18 (+++), р63 (nuclear ++), E-cadherin (+++), EGFR (+), and CD-117(++) by tumor cells, as determined by immunohistochemical assay, and focal expression of CG (++) and PLAP (+) by these cells.
