Aspiration cytology
The most famous ones are FNA, fine needle aspiration biopsy (FNAB), and needle aspiration biopsy cytology (NABC)..
Aspiration cytology is either nonspecific or it shows chronic inflammatory exudates with large numbers of neutrophils, lymphocytes, and macrophages.
A few groups of nonatypical bland cuboidal to columnar epithelial cells, occasionally arranged in papillary clusters, may be seen (Logro\xf1o et al, 2002)..
Aspirates of cystic bone lesions yield more material than firm lesions do.
However, it is reported that, the diagnosis of aspirates from cystic lesions may be less specific than the FNAC diagnosis of solid lesions due to the paucity of specific lesional cells in the former..
Aspiration or suction is a commonly used technique in modern biological technology, such as cell culture, for the removal of liquid media.
Cell culture refers to the process of culturing eukaryotic or prokaryotic cells in a controlled environment, allowing them to grow and proliferate in a culture medium..
Aspiration cytology, by contrast, employs a needle to extract cells from a lesion and is used to diagnose a variety of suspicious superficial and deep masses..
A type of biopsy procedure where a thin needle is inserted into an area of abnormal-appearing tissue or body fluid to make a diagnosis.
It's generally considered safe with infrequent complications.
The fine needle aspiration itself is usually a short procedure (less than 10 minutes).
The biopsy sample may be examined under a microscope right away.
This will let your doctor:
Your skin over the area of procedure will be cleaned with antiseptic solution then covered with sterile drape/towels; numbing medication may be injected under your skin; ultrasound may help locate right area; vacuum inside syringe causes body fluid/tissue suctioned into needle & syringe during short procedure (less than 10 minutes).
Results can tak.
No one standard preparation before fine needle aspiration but you may be asked to stop taking aspirin or other blood thinners several days before the test and not eat or drink anything for several hours before it.
If sedating medication will be used bring someone with you to drive home.
The most common reason to get fine needle aspiration is to test for cancer, especially in the breast, thyroid gland and lymph nodes in the neck, groin or armpit.

CodyIII MDAttending Surgeon, in Hughes, Mansel & Webster's Benign Disorders and Diseases of the Breast (Third Edition), 2009 Aspiration cytology may be used to take samples from very small mobile lesions which cannot be biopsied and can also be used to obtain cells in very small screen-detected lesions.
Chiba needle aspiration cytology was pioneered in Japan in the 1950s using 22-gauge long percutaneous needles.
Still the standard for most radiologically guided biopsies, Chiba needle aspiration has proved exceedingly safe and is widely applied.
A core biopsy and fine needle aspiration are both types of needle biopsies.
The needle for a core needle biopsy is wider than that used for FNA.
A core biopsy gathers more tissue that can provide more information about the suspicious area than FNA can.
