Great discussion and comments! I did not include cytology imprint pictures. I am surprised that nobody is asking for it. Here are two pictures of cytology - it might be useful to narrow down your differential diagnosis and immunohistochemical workup.

- For small biopsy, touch prep imprint cytology should always be done before frozen section
- When suspicious for lymphoma, remember to save tissue for flow cytometric study, permanent H&E section, and other possibel studies
- Cytologic diagnosis is very valuable adjunct for the correct intraoperative frozen section diagnosis
- If possible, get patient's history from the surgeon before or during the surgery
Frozen diagnosis: atypical lymphoid proliferation, suspicious for lymphoma
Final diagnosis: Large B cell lymphoma (confirmed by flow cytometry)
