Metastatic poorly differentiated neuroendocrine carcinoma of pulmonary origin. Tumor presents as a mass (Row 1 Left 40X). Tumor replaces most of a triad; note the residual interlobular bile duct [arrow] (Row 1 Right 200X). Tumor cells mold, show scant cytoplasm, and marked anisonucleosis, larger than ordinary small cell carcinoma (Row 2 Left 400X). Tumor cells are positive for CK7 (Row 2 Right 400X). Tumor cells are positive for TTF1 (Row 3 Left 400X). Tumor cells are positive for CD56 (Row 3 Right 400X). | |||
