Serous cells with granular cytoplasm
resembling normal acinic cell, but unlike
the distinct “bunches of grapes”
arrangement of benign acinic cells
intermixed with ductal cells, this FNA
shows only sheets of acinic cells.

parotid
A. Benign salivary gland
B. Warthin’s tumor

intermediate cells (green), and
mucin secreting cells (yellow).
A. Adenoid cystic carcinoma

10. 5

12. 6
29 year old female. Peritoneal
lavage.
A. Amebiasis
B. Reactive mesothelial cells
C. Lymphoma
D. Adenocarcinoma
E. Metastatic papillary thyroid
carcinoma

13. 6
29 year old female. Peritoneal
lavage.
A. Amebiasis
B. Reactive mesothelial cells
“Daisy cells” are normal mesothelial cells with
multiple deep nuclear indentations.
Apparently, this type of cell is only seen in
peritoneal mesothelial cells.

tissue
B. Pleomorphic
adenoma
Poorly cohesive epithelial-like
cells associated with
fibromyxoid stroma.
A. Warthin’s tumor
B. Adenoid cystic
carcinoma
C. Acinic cell carcinoma

16. 8

mass
A. Negative for malignancy

C. Metastatic squamous cell ca
D. Metastatic melanoma
E. Amebic abscess

17. 8
69 year old male. FNA of neck
mass
