10
1.
A Reactive
•
Multi-nucleated bronchial epithelial cell. Sometimes they do that…not related to tumor or specific virus
E Reactive – endobronchial cells and macrophages
2.
•
3.
Open chromatin, reactive nucleoli. No tumor in this.
E HSIL
•
4.
High NC ratio, irregular nuclei
B Non-small cell lung CA
•
5.
Probably squamous. Too much cytoplasm for neuroendocrine or small cell. NC ratio and
hyperchromatic nuclei would argue against granuloma
C Indeterminate
•
6.
The scant colloid and sheets or follicular cells (photo) in a microfollicular pattern would suggest a
follicular lesion, but we can’t assess adenoma vs carcinoma on FNA so we call them indeterminate.
D LSIL
•
7.
Koilocytes again!
A Metastatic breast CA
•
8.
Mucin in the cytoplasm – almost forming a signet ring.
B Reactive endocervical cells
•
Normal. No dysplasia in this one.
D. Neoplasm – Papillary thyroid carcinoma
9.
•
10.
See the nuclear pseudoinclusion…….
A Reactive urothelium/umbrella cell
•
They can be binucleate. Looks like HPV – but it’s urothelium and not related in any way to HPV in cervix
