What is cytology and cytopathology?
Technically speaking, cytology is the study of individual normal cells, but it is always used in conjunction with cytopathology, which is the study of diseased cells. The human body is born with a single cell; it then divides and differentiates into tissues, organs, organ systems, and then an entire human being.
What is the difference between histology and cytology?
The main difference between histology and cytology is that histology is the examination of tissue under a microscope while cytology is the examination of cells under a microscope. Histology focuses on providing excellent details of tissues and cytology on offering excellent details of cells.
What is cytopathology in lymphoma?
More in Lymphoma. Cytopathology is the study of disease at the cellular level. "Cyto" refers to cell and "pathology" to disease. Cytology tests are done on cells in fluid aspirations, scrapings or brushings to look at single cells or small clusters of cells and assess whether they are normal or show signs of disease.
How do you do a cytopathology procedure?
Cells examined for cytopathology can come from fluids such as urine or sputum or may be extracted from tissue, such as from inside the chest or abdomen. Cells can also be extracted by inserting needles into growths or diseased areas or tissues—such as with a fine-needle aspiration cytology (FNAC) procedure.

Urinary cytology is most helpful in diagnosing invasive high-grade (the cancer cells grow and spread quickly) tumors and carcinoma in situ (a group of abnormal cells that are found only in the place where they first formed in the body). It has a 95% accuracy rate for diagnosing these two conditions.

Is cytopathology a Pap smear?
Cytopathology is a diagnostic technique that examines cells from various body sites to determine the cause or the nature of disease. The first cytopathology test developed was the Pap test, which has been widely utilized in the last 50 years for screening and diagnosing of cervical cancer and its precursors.
What is the difference between biopsy and cytology?
A cytology test is different from a biopsy. During a biopsy, tissue from a certain area of the body is removed and analyzed for cancer. A cytology test removes and studies a fewer number of cells.

What is the role of histopathology in cancer?
While cytopathology relates to abnormalities found within—or expressed by—individual cells, histopathology extends the analysis so that pathologists can see abnormalities related to attachments between cells , and explore whether the cell appears normal given its location within the tissue. This is sometimes referred to as "histological architecture," which can be important in the evaluation of the appearance of conditions such as cancer. 3
Why do we do cytology?
Cytology can also be done to assist in the diagnosis when there is a known or suspected disorder, such as when a fine needle aspiration is used to sample cells from a tumor.

Histopathology looks at chunks of biopsy tissue that are processed (dehydrated) sliced very thinly and placed on a slide for various staining for various reasons. They can also take fluids and spin them down and slice the plug as a piece of tissue and stain with various stains. Silver stains were used on sputum to identify Pneumocystis Carnii in the old days (70’s) before HIV had a name. It was just a strange Immunodeficiency syndrome and people’s immune system got so weak that spores we are exposed to ev
What does a pathologist do when a slide is abnormal?
The pathologist will take out a thin layer of cells and prepare a smear from there. This smear will then be processed appropriately and visualised under microscope. If the Pathologist finds any abnormalities in the slide, then the pathologist will inform the surgeon that a biopsy is needed for confirmation.
