Male pathology Flashcards
Benign prostatic hyperplasia - age
common in over 50
Benign prostatic hyperplasia - appearance/result
smooth elastic, firm nodular enlargement (HYPERPLASIA, not hypertrophy) of periurethral (lateral and middle lobes) –> compress urethra into a vertical slit
Benign prostatic hyperplasia - hyperplasia or hypertrophy
hyperplasia
Benign prostatic hyperplasia - location of hyperplasia
periurethral - lateral and middle lobes
Benign prostatic hyperplasia - cancer
not premalignant
Benign prostatic hyperplasia - presentation
- increased frequencey of urination
- nocturia
- difficulty starting and stoping urine stream
- dysuria
Benign prostatic hyperplasia - complications
may lead to distention and hypertrophy of bladder, hydronephrosis, UTIs
Benign prostatic hyperplasia - markers
increased PSA
Benign prostatic hyperplasia - treatment (and mechanism)
- a1 antagonists (terazosin, tamsulosin) –> relaxation of SMC
- 5α-reductase inhibitors (eg. finasteride
- tadalafil (PDE-5 inhibitor)
Prostatitis - divided to/due to
- acute: bacterial (eg. E.coli)
2. chronic (bacterial or abacterial)
Prostatitis - symptoms
- dysuria
- frequency
- urgency
- low back pain
Prostatitis - physical examination
warm, tender, enlarged prostate
Prostatic adenocarcinoma - age/location
men over 50
often posterior lobe (peripheral zone) of prostate gland
Prostatic adenocarcinoma - diagnosis
increased PSA and suvsequent needle core biopsies
Prostatic adenocarcinoma - markers
Prostatic acid phosphate (PAP)
PSA
PSA - in Prostatic adenocarcinoma
increased total with decreased fraction of free
PSA - normal range
- increases in age by BPH
- under 2.5 ng/ml in 40-49
- under 7.5 ng/ml in 70-79
Prostatic adenocarcinoma - complication
osteoblastic metastasis (late stages)
Prostatic adenocarcinoma - osteoblastic metastasis - sympotms/labs
- lower back pain
2. increased ALP and PSA
Tunica albuginea?
- penis –>connective tissue that surrounds the corpora cavernosa
- testicles –> connective tissue covering the testicles
- ovaries –>the connective tissue covering of the ovaries
Penile pathology - 3 diseases
- Peyronie disease
- iscemic priapism
- SCC
- penile fracture
Peyronie disease - definition/mechanism
abnormal curvature of penis due to fibrous plaque within tunica albuginea (goes up)
Peyronie disease - symptoms
- pain
- anxiety
- erectile dysfunction
Peyronie disease - treatment
surgical repair once curvature stabilizes
penile fracture - definition/mechanism
rupture of corpora carvenosa due to force bending
Ischemic priapism - definitim
painful sustained erection lasting more than 4 hours
causes of ischemic priapism
1 sickle cell anemia (trapped RBCs in vascular channels)
2. drugs (sildenafil, trazodone)
ischemic priapism - management
treat immediately with corporal aspiration, intracavernosal phenylephrine, or surgical decompression to prevent ischemia
SCC of penis - epidimiology
more common in Asiam Africa, South America
SCC of penis - precursor in situ lesions
- Bowen disease
- erythroplasia Queyrat
- Bowenoid papulosis
SCC of penis - risk factors
- HPV
2. lack of circumcision
Bowen disease?
leukoplakia in penile shaft
erythroplasia Queyrat?
cancer of glans (IN SITU), presents as erythroplakia
Bowenoid populosis?
carcinoma in situ of unclear malignant protention, presenting as redish papules
SCC of penis - precursor in situ lesions/and their definition
- Bowen disease –> leukoplakia in penile shaft
- erythroplasia Queyrat –> in situ carcinoma of glans, presents as erythroplakia
- Bowenoid papulosis –> carcinoma in situ of unclear malignant protention, presenting as redish papules
Cryptorchidism - definition
undescended testis (one or both)
Cryptorchidism - sperm vs testosterone - mechanism
- impaired spermatogenesis: sperm develops best at less than 37. sertoli are Q sensitive
- normal Testosterone levels (Leyding unaffected to Q)
