Original magnification 64X. A patient with a typical fibrolamellar carcinoma had a subsequent lymph node metastasis. The metastatic carcinoma had a distinctive glandular growth pattern that mimicked a cholangiocarcinoma. However, the metastatic tumor was still HepPar positive ((b), original magnification 64X), CD68 positive ((c), original magnification 64X). Cytokeratin 7 was also strongly positive (not shown), while cytokeratin AE1/3 was weakly positive ((d), original magnification 64X).
