Penis (Pathology) Flashcards
Phimosis?
abnormal narrow and long (foreskin)
- hygiene
smegma (material around glands) = carcinogenic (100% of cases)
Congenital anomalies of penis?
Epispadias - open dorsal surface Hypospadias - open ventral surface (MC) - obstruction - infertility - infections
Paraphimosis?
forcible retraction –> extremely painful, severe congestion of glans, obstruction
Balanitis
inflamation of the glands
Balanoposthisis
infection of glans, prepuce
- candida
- mycoplasma
Gonorrhea in penis?
retrograde spread = epiditimal orchitis
cause strictures from fibrosis healing
Syphilis course?
- 6 wks, localized smptoms (chancre)
- 6 mons, asymptomatic (rash, condyloma lata)
- tree bark aorta, CNS, paralysis, spinal cord, granulomatous lesions
Histology in syphilis
obliterative endarteritis –> loss lumen
plasma cells - cuff around the vessels
Chanchroid
painful and soft lesion
Lymphogranuloma venerum
Chlamydia trachomatis
rectum involved
stellate abscess
Granuloma inguinale
calymmatobacterium donovani
donovan bodies
rare in US
Condyloma accuminatum
genital warts
HPV 6,11 (no malignancy)
koilocytic change (perinuclear halo)
infect squamous cells
Bowen’s disease
carcinoma in situ - cancerous cells, BM intact HPV 16 >30 yrs solitary , gray white \++ other malignancies visceral
Erythroplasia of Queyat
more dysplasia
shiny red plaque
variant of carcinoma
Bowenoid papulosis
looks like Bowen HPV 16 multiple, red brown <30 yrs no malignancy
Squamous Cell Cercinoma (penis)
60 yrs non-circumcised HPV 16, 18 keratin pearls prog: <50% no LN, 30% LN
early circumcision can prevent
Cryptorchisim
Failure to descend through inguinal canal
Testicular cancer with cryptorchidism?
abdomen - infertility, testicular cancer (seminoma)
inguinal - trauma, infertility, hernia
Atrophic changes with cryptorchidism?
sparing leydig cells
hyalinization of seminiferous tubules/interstitial fibrosis
Treatment for cryptorchidism?
if after 1 yrs pull it down
if before 1 yr it can still descend
MUST before 2 yrs
orchiopexy - pull down and ligating to the sack
result of orchiopexy
infertility - 20-25% may regain
cancer risk - unchanged
if cancer - easier to palpate for cancers
where do you see testicular atrophy?
- Kleifelter syndrome
- to many things (criptorchidism etc.)
lead to infertility
Histology of testicular atrophy
sparing Leydig cells
hyalinization of seminiferous tubules
Non-specific epididymitis/orchitis
children?
adults?
older adults?
children = gram - rods adults = chlamydia, neisseria older = e.coli, pseudomonas
granulomatous orchitis
autoimmune orchitis
sudden onset with fever
granulomas (seminiferous tubules)
DD: Tb (everywhere)
gonorrheal epidimymo-orchitis retrograde infection
spread to testes/prostate (untreated)
mumps orchitis
adults
after parotitis
unilateral
with mumps pancreatitis
mononuclear cells infeltrate
Tx: steroids
tuberculous epididymo-orchitis
primarily in epiditimis
caseating granulomas
syphilitic orchitis
start in testes
rarely spreads
torsion of testes
twisting of spermatic cord
arterial/venous obstruction
cause: crimtochitism, testicular atrophy, absence of oscrotal ligaments
what must be done with testicular torsion?
orchiopexy of unaffected side as well
where do you see torsion?
testes and ovaries
venous infarction
MC cancer in testes?
seminoma
germ cell tumors?
seminoma
nsgct
seminomas types?
- classic (MC)
- anaplastic
- spermatocytic
PAP marker
40s
NSGCT classes?
- embryonal ca. 30s,testicular shape lost
- yolk sac tumor (M,F <3yrs, schiller-duval bodies, AFP)
- choriocarcinoma (Beta-hCG) metastases
- teratoma (children mature)
- mixed tumors
choriocarcinoma
- gestational (abortion, pregnancy, mole)
- gonadal (testes, ovaries)
absent of chorionic villi
produce Beta-hCG
bad treatment - single drug(methotrexate)
non-GCT classes?
- leydig cell (++testosterone)
- sertoli cell (++estrogen)
- lymphoma B-NHL (MC >60yrs, worst prog)
clinical features of GCT?
- painless mass enlargement of testes
2. spread through blood and lymph
staging of GCT?
1-confirmed testes
2-spread below diapharam
3-above diaphram
seminoma testicular shape?
maintained shape
intact tunica albuginea
no hemorrhage
no necrosis
histology of seminoma?
seminoma cells with l ymphocytic infiltrates and granulomas
NSGCT testicular shape?
lost testicular shape + local invasion
treatment for seminoma?
RT effective - not aggressive
NSGCT treatment?
not effective and can be aggressive
teratoma classes?
3 germ layers
- mature (children)
- immature (adults)
- mondermal malignancy (SCC, AdeC)
histology in leydig cell tumor?
Reinke crystalloids (eosinophilic cytoplasm) 90% benign
