There are several potential pitfalls and mimics encountered in the evaluation of FNA cytology specimens, making interpretation of malignant cytology challenging. Familiarity with the mimics and the pitfalls is essential in avoiding a misdiagnosis because a false positive or false negative diagnosis may have significant management implications. This presentation focuses on representative cases of FNA cytology - with potential mimics discussed under each tumor category.

What is imprint cytology (preparation technique)?
Suitable samples
1. Thyroid gland (what can we do for follicular lesions, differentiate follicular neoplasm from follicular variant PTC, HTT, or others, 2 cases).
2. Sentinel lymph nodes (breast, melanoma, 1 case, apply immunocytochemical stain).
3. Tumor margins (breast, 1 case).
4. Small biopsy specimen (lung or pleura, 2 cases).
5. Hematolymphoid specimens (lymph nodes, mediastinum, 2 cases).
6. CNS samples (lymphoma, glioma or metastasis, 3 cases).
7. Small round blue cell tumors (broad differentials but substantially different management, 1 case).
8. Ovary frozen (1 case).
