PAP immunohistochemical staining is often used with PSA (staining), by pathologists, to help distinguish poorly differentiated carcinomas.For example, poorly differentiated prostate adenocarcinoma (prostate cancer) and urothelial carcinoma (bladder cancer) may appear similar under the microscope, but PAP and PSA staining can help differentiate them; [7] prostate adenocarcinoma often stains ...
Papanicolaou stain (also Papanicolaou's stain and Pap stain) is a multichromatic (multicolored) cytological staining technique developed by George Papanicolaou in 1942. [ 1 ] [ 2 ] [ 3 ] The Papanicolaou stain is one of the most widely used stains in cytology , [ 1 ] where it is used to aid pathologists in making a diagnosis.
Pap stain. Gynaecologic cytology, also gynecologic cytology, is a field of pathology concerned with the investigation of disorders of the female genital tract. [1] The most common investigation in this field is the Pap test, which is used to screen for potentially precancerous lesions of the cervix.

The papanicolaou stain is now used in place of cytological staining in all organ types due to its increase in morphological quality, decreased staining time, and decreased cost. It is frequently used to stain Pap smear specimens. [11] It uses a combination of haematoxylin, Orange G, eosin Y, Light Green SF yellowish, and sometimes Bismarck Brown Y.
Pap stain. High-grade squamous intraepithelial lesion (HSIL or HGSIL) indicates moderate or severe cervical intraepithelial neoplasia or carcinoma in situ. It is usually diagnosed following a Pap test. In some cases these lesions can lead to invasive cervical cancer, if not followed appropriately. [citation needed]
Vaginal squamous cell with normal vaginal flora versus bacterial vaginosis on Pap stain. Normal vaginal flora (left) is predominantly rod-shaped Lactobacilli , whereas in bacterial vaginosis (right) there is an overgrowth of bacteria, which can be of various species.
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), [1] cervical smear (BE), cervical screening (BE), [2] or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women).
