Lymphoepithelial‐like carcinoma of the uterine cervix

Abstract

Lymphoepithelial-like carcinoma of the uterine cervix is very rare in Caucasian women. We present a new case in a 74 year-old European. Morphologically the undifferentiated carcinoma was accompanied by intense lymphocytic infiltration. Immunohistochemically the tumor expressed epithelial markers such as cytokeratin CAM 5.2, and a large proportion of cells expressed the proliferating cell nuclear antigen. The accompanying lymphocytic reaction was composed predominantly of T-lymphocytes which express the UCHL1 antigen. The in situ hybridization of the Epstein-Barr virus genome and the human papillomavirus proved negative.
