urogenital pathology Flashcards
define nodular hyperplasia or benign prostatic hyperplasia.
enlargement of the prostate due to overgrowth of the epithelium and fibromuscluar tissue of the transitional zone and periurethral area.
symptoms of benign prostatic hyperplasia
Lower urinary tract infections
Interference with muscular sphincter and by the obstruction of urine flow through pros attic urethra.
4 zones of the prostate.
normal prostate=central, transitional, peripheral and periurethral zone.
where does nodular hyperplasia originate from- (which zone of the prostate)
most centrally situated glands
this location enables it to produce early urinary obstruction.
3 pathologic changes needed to develop nodular hyperplasia
nodule formation
diffuse enlargement of transitional zone and periurethral tissue.
enlargement of the nodules.
what effect on cell proliferation do the androgens which can use benign prosaic hyperplasia have
increase cell proliferation and reduce cell death.
in what age group are prosaic cancers most prevalent
over 40s
treatment for prostatic cancer
Surgery, radiation therapy, and hormonal manipulations (antindrogenic), external beam radiation, prostatectomy.
risk factors of developing benign prostatic hyperplasia
age, race, family history, hormone levels, environmental influences.
what hormones play a key role in benign prostatic hyperplasia
androgens- maintain growth and survival of prostate cancer cells.
germline mutations in what predispose you to prostate cancer
BRAC2
what is the grading system from prostate cancers called
Gleason scoring system.
can prostate cancer be screened for
Yes- prostate specific antigen.
what is the role of the testes
produce sperm and produce androgens.
Testes are made up of what structures
tubules lined by spermatogonian (cells which differentiate and form sperm).
support cells- leydig and sertolii
what are the different types of testicular cancer
PRIMARY germ cell non-germ cell pure cell mixed cell miscellaneous haematopoietic teratomas= most common SECONDARY metastases
