The prostate is a small organ that sits under the bladder in men, and provides a nourishing fluid that helps transport sperm. It often enlarges as men age, most commonly as benign tissue growth ...
Adenoma is a benign tumor of glandular tissue, such as the mucosa of stomach, small intestine, and colon, in which tumor cells form glands or gland-like structures. In hollow organs (digestive tract), the adenoma grows into the lumen - adenomatous polyp or polypoid adenoma. Adenomatous polyps may be classified based on morphology in order to ...
Prostate biopsy is a procedure in which small hollow needle-core samples are removed from a man's prostate gland to be examined for the presence of prostate cancer. It is typically performed when the result from a PSA blood test is high. [ 1 ]
A histopathologic diagnosis of prostate cancer is the discernment of whether there is a cancer in the prostate, as well as specifying any subdiagnosis of prostate cancer if possible. The histopathologic subdiagnosis of prostate cancer has implications for the possibility and methodology of any subsequent Gleason scoring . [ 1 ]
Normal (left) versus dysplastic (large at right) colonic crypts, the latter conferring a diagnosis of a tubular and/or villous adenoma. Histopathology of high-grade dysplasia in a tubulovillous adenoma, in this case seen mainly as loss of cell polarity, as cells become more plump and haphazard than the elongated and parallel nuclei of ...
Abscess of the prostate (red arrow) resulting in urinary retention (blue arrow) Abscess of the prostate (red arrow) resulting in urinary retention (blue arrow) Acute prostatitis is relatively easy to diagnose due to its symptoms that suggest infection. The organism may be found in blood or urine, and sometimes in both. [2]
Next, tumor samples are graded based on how much the tumor tissue differs from normal prostate tissue; the more different the tumor appears, the faster the tumor is likely to grow. The Gleason grading system is commonly used, where the pathologist assigns numbers ranging from 3 (most similar to healthy prostate tissue) to 5 (least similar) to ...
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination, trouble starting to urinate, weak stream, inability to urinate, or loss of bladder control. [1]
