The presence of epithelial cells in urine may indicate infections, kidney disease, or (very rarely) a serious illness such as a tumor. Symptoms of squamous cell bladder cancer The symptoms of squamous cell bladder cancer are similar to those of other types of bladder cancer. Squamous cells often are involved in abnormal Pap smears, as in a diagnosis of ASCUS ( Atypical Squamous Cells of Undetermined Significance ), 2 which indicates the presences of unusual cells that are not clearly benign or bad. Rarer cancers include squamous cell carcinoma, small cell carcinoma, and adenocarcinoma. If there are squamous epithelial cells in your urine, it may mean your sample was contaminated.

In men, the origin of the squamous cells is the terminal portion of the urethra or, in rare cases, a vaginal type of squamous metaplasia. The majority of these squamous cells are intermediate in appearance. The sensitivity of homozygous 9p21 deletion for urothelial carcinoma is 28.6%. Sep 15, 2019 3:57 PM. Benign squamous cells are often seen in the urine specimens of women, they are either exfoliated from the trigone area of the bladder, the urethra, or the cervicovaginal region.

Its normal to have one to five squamous epithelial cells per high power field (HPF) in your urine. Potentially pre-cancerous, abnormal Pap smear results are sometimes diagnosed as squamous intraepithelial lesions. The UroVysion test: 72% sensitivity and 83% specificity. This means that the sample contains cells from the urethra (in men) or the vaginal opening (in women). Urothelial cells form the inner lining of the renal pelvis, ureters, bladder and urethra. However, abnormal squamous cells in the urine raise concerns of abnormalities of the urinary tract and cervicovaginal area which range from squamous metaplasia of the urothelium, a Can squamous cells be benign?

It begins in urothelial cells, which line the inside of the bladder and other parts of the urinary tract. The individual sensitivity of the centromeric probes is 73.7% for chromosome 3, 76.2% for chromosome 7, 61.9% for chromosome 17. This is a benign proliferative lesion, composed of papillary cores covered by squamous epithelium without koilocytic atypia or dysplasia. What is urine cytology? Squamous Epithelial Cells, Both Superficial and Intermediate. Melanocytes can also form benign (non-cancerous) growths called moles.

(600x) Figure 1.9. Squamous cell carcinoma. Benign Urothelial Cellscatheterized urine: In this catheter-ized urine, a large group of benign urothelial cells is present at a low power. Urine cytology is mainly used to detect urothelial carcinoma (UC), especially for highgrade lesions including urothelial carcinoma in situ. Voided urine sediment may also contain squamous cells derived from the vulva, vagina, or uterine cervix. Some of these include medications for pain and medications that thin the blood. This means that the sample contains cells from the urethra (in men) or the vaginal opening (in women). Optimal Result: 0 - 3 HPF. It's used with other tests and procedures to diagnose urinary tract cancers, most often bladder cancer. The presence of PMV on exfoliated squamous cells in cytologic material from the human urinary tract does not seem to have the same diagnostic and prognostic significance as the presence of PMV on Urinary cytology identifies malignant cells that have been exfoliated from the urothelium into the urine. UBC is cancer of the lining of the urinary system. Squamous cells are present in other parts of the body, such as the lungs. The presence of PMV on otherwise-benign-appearing squamous cells in urine or bladder washing specimens may be a source of confusion in the interpretation of SEM findings. The most common cause of epithelial cells in urine is improper urine sample collection. The specificity of cytology is greater than 90% [], while the sensitivity for high-grade disease and carcinoma-in-situ (CIS) can be as high as 80 to 90% [6, 7].As indicated before, however, the main shortcoming of voided cytology is the The presence of squamous epithelial cells in your urine sample may mean it was contaminated by cells from the urethra or vagina opening.
