Cytology of lymph node

If you have a swollen lymph node (gland) in your neck your doctor checks it with an ultrasound scan.
If it looks abnormal they might take a biopsy.
This means they use a thin needle to draw cells and fluid out of the lymph node.

Lymph node cytology is an excellent way to evaluate a lymphadenopathy whether it is a single node enlarged, multiple nodes enlarged, or a generalized lymphadenopathy.

Lymph node FNA and cytology is a noninvasive, rapid, and cost-effective diagnostic tool. A good-quality smear and the ability to distinguish a diagnostic specimen from a nondiagnostic one are critical first steps in sample evaluation.

What is a pattern based approach to lymph node cytology?

A sequential, pattern-based approach to lymph node cytology is outlined, together with a summary of the types of ancillary tests available, with an emphasis on one’s individual laboratory practice setting.

What is the cytological diagnosis of lymph node enlargement?

The cytological diagnosis of lymph node lesions is extremely challenging because of the diverse diseases that cause lymph node enlargement, including:both benign and malignant or metastatic lymphoid lesions.
Furthermore, the cytological findings of different lesions often resemble one another.

Why is lymph node cytology important?

Thus, appreciation of lymph node cytology is a good starting point in the study of cytopathology, where one can encounter the many different morphologic patterns of disease that can also occur in extranodal locations.
