PIK3CA and p53 Mutations by Next Generation Sequencing in Lymphoepithelioma-Like Carcinoma of the Endometrium

Figure 3

Immunohistochemical aspect of lymphoepithelioma-like carcinoma. Positivity of epithelial component for cytokeratin AE1/AE3 (a) and in mirror of the stromal lymphocytes for CLA (b). Note that CD8+ cytotoxic T-lymphocytes are numerous (c). Strong nuclear expression of tumor cells for the p53 (d) and lesser for MLH1 (e). PDL1 expression was restricted to some stromal lymphocytes but the epithelial cells were negative (f).
