Breast carcinoma metastases in endometrium and myometrium were confirmed histopathologically and immunohistochemically with positivity of pancytokeratin and gross cystic disease fluid protein-15 (GCDFP-15) and negativity of Melan A, CD 10, caldesmon, and alpha-fetoprotein (AFP) (Figure 2). Here, AFP is linked to breast carcinoma.
