How are cytology specimens collected?
Cytology samples can be collected from solid lesions by several techniques including: Aspiration cytology – fine needle aspiration (FNA): Ideal for cutaneous or subcutaneous masses since it avoids surface contamination.
What is cytological examination?
Cytologic evaluation is the analysis of cells from the body under a microscope. This is done to determine what the cells look like, and how they form and function. The test is usually used to look for cancers and precancerous changes.
How do you prepare cell samples for cytological study?
In the cytology laboratory various sample preparation steps are performed prior to analysis including centrifugation to concentrate cells in dilute samples, followed by preparation and staining of slides, and examination under a light microscope (Figure 1).
What is cytological specimen?
Cytology: A specimen is ordered as a “cytology” when no core biopsy has been obtained. This is when the aspirate is used to make cytology smears and placed in the cytojar ONLY. Examples of cytology specimens include fine needle aspirations of thyroid, pancreas, cysts etc.

What are cytological features?
The general features of malignancy in cytological slides are high cellularity, cellular enlargement, increased nuclear/cytoplasmic ratio, nuclear hyperchromasia, discohesiveness of cells, prominent and large nucleoli, abnormal distribution of nuclear chromatin, increased mitotic activity and specially the presence of …
