     Others are large and
     hyperchromatic.

                              Some of the malignant cells
                              are splindled.

FNA of thyroid.                    This papillary structure viewed
A. Reactive, neg for malignancy    at high power demonstrates
B. Goiter                          cells with high N/C ratios,
C. Indeterminate for malignancy.   hyperchromasia, and
D. Papillary carcinoma.            intranuclear inclusions.
E. Follicular carcinoma.




  Intranuclear
  inclusion




                                                                     6
54 yo female with pleural effusion
A. Reactive mesothelial cells
B. Adenocarcinoma
C. Mesothelioma
D. Melanoma
E. Lymphoma



       This “cannon ball” of tumor
       cells is characteristic for
       breast carcinoma in pleural
       fluid. Other
       adenocarcinomas may
       form large proliferation
       spheres as well. Adenoca’s
       have smooth community
       borders, whereas
       mesotheliomas tend to
       have a more knobby
       outline.

                            7
FNA of pancreatic mass.
A. Unsatisfactory specimen
B. Reactive cells
C. Pseudocyst contents
D. Pancreatic adenocarcinoma
E. Amebiasis


                               Compare the malignant cells to
                               the reactive ductal cells
                               arranged in a orderly
                               honeycomb pattern. The
                               malignant cells are less
                               cohesive.
                               Did you notice the tumor
                               diathesis in the background?
