Immunohistochemistry of a well-differentiated endometrioid carcinoma in a 43-year old patient in FIGO stage IC who survived 73 months without recurrence. The tumor shows heterogeneity for CD44 (a), vimentin (b) and E-cadherin (c), negative epithelial staining for CD44 and vimentin and negative for E-cadherin and vice versa for stromal staining indicated with arrows. Negative staining for CD44 and vimentin and positive for E-cadherin indicated with closed asterisks. The adjacent stroma is either negative or only weakly stained. Open asterisks indicate positive epithelial staining for CD44 and E-cadherin with negative stromal staining and negative epithelial vimentin staining with positive stromal staining.
