Figure 5.9. (B) Metastatic papillary serous carcinoma of the
ovary. Histologic section of the corresponding tumor shows a welldeveloped
papillary architecture with associated psammoma bodies.
(Hematoxylin and eosin.)
Figure 5.10. Metastatic medullary thyroid carcinoma. An irregular
fragment of pleomorphic malignant cells with high nucleus to cytoplasm
ratios and prominent pleomorphism and anisonucleosis. A
rare intranuclear inclusion is seen toward the center. There is nothing
in this smear to suggest a medullary carcinoma diagnosis. Clinical
history and immunoperoxidase staining are crucial when dealing
with metastasis in the breast. (Smear, Diff-Quik.)
