Penis congenital issues
Hypospadius (ventral malformation of urethral groove)

Epispadias - dorsal
Epispadius
Dorsal malformation of urethral groove

Associated with poor testicular descent, urinary tract malformations, opening constricted (inc risk of infection), and chordee (ventral bending of penis that can also be associated with hypospadius)
Phimosis
Orifice of prepuce (foreskin) is too small to normally be retracted behind glans penis.


Can be congenital or acquired (inflammation - balanoposthitis or balantis - often interferes with hygiene and predisposes to infection or CA)
Balanoposthitis
Inflammation of glans and prepuce (foreskin) to cause phimosis

When phimotic prepuce is forcefully retratacted over glans and it can't be replaced and it swells.

Can cause urethral constrictio and acute urinary retention.

Condyloma lata - broad elevated plaques in moist areas of skin
Tertiary syph
Aortitis - endarteritis of vasavasorum of prox aorta leading to scarring and dilation of aortic root and arch leading to aneurysm of proximal aorta (aortic insufficiency leading to infarcts)

Narrowing of coronary ostia leading to infarcts

Neurosyph - meningovascular syphilis, tabes dorsalis and paresis (impaired sensatio fo pain, position, ataxia..)
Can also get delusions of grandeur

Gummas - Focal point of central necrosis surrounded my macrophages. Common in skin, subcut tissue, bones, joints.
How to ID spirochetes (syphilis)
They are delicate, slender, use silver stain.
Gonorrhea
Neisseria gonorrhoeae (gram neg diplococci)

urethritis with discharge
Can ascend to epididymitis, orchitis (inflamm of testis) and infertility
Which pop has resurgence of syphilis?
HIV +
Chancroid
Haemophilis ducreyi

Acute, tender, erythematous ulcers, lymphadenopathy with buboes

Painfil acute ulcers
Granuloma inguinale
Klebsiella granuomatosis (calymmatobacterium donovani)

Leads to elephantiases of ext genirals because of lymph obstruction and scarring
Microscopic view of granuloma inguinale
Pseudoepitheliomatous hyperplasia

Donovan bodies - Use Giamsa stain. Minute encapsulated organisms in macrophages
Lymphogranuloma venereum
Chlamydia trachomatis
Most common STI (bacterial) in the world

Starts as ulcer, can get chronic lymphatic obstruction.

Stellate (star) shaped abscesses with granulomatous appearance surrounded by neutrophils.
Genital herpes
Herpes simplex virus type 2

Vesicles on mucous membranes and external genitalia - has clear fluid in it.

Can become rapidly superficially ulcerated.
Microscopy of herpes
Looking for mulinucleation and modulation of chromatin

Dx made by scraping lesions and obtaining Tzank smear.
Lichen sclerosus
Balantis xerotica obliterans

Usually in older men and is asymptomatic

Autoimmune

Appears as white patch

A dermatosis

Can lead to phimosis or carcinoma.
Micro of lichen sclerosus
Homogenized collagen band
Peyronie's disease
Caused by dense fibrous band or plaque involving tunica albuginea along shaft resembling fibromatosis.

Presents with bending of penis on erection

Associated with Dupuytren's contractures, coiral trauma, urethral instrumentation, beta blockers, HTN, diabetes...
Penile cysts
Epidermal cysts - most common - often on shaft

Mucoid cysts - lined with column epithelium fille with mucous. usually on prepuce or glans

Median raphe cysts - secondary to incomplete closure of genital fold.
Condyloma acuminatum
Benign tumor.

Caused by HPV (usually benign ones - types 6 and 11)

Flat, warty, papillary
Hallmark micro appearance of condyloma acuminatum
Koilocyte - epithelial cell with hyperchromatic/shriveled nucleus surrounded by large halo.
Carcinoma-in-situ
Precancerous lesion in epithelium

3 lesions with similar histo (but not gross) features
Bowen's disease - Crusty lesion. older males can dev to CA
Erythroplasia of Queyrat - Shiny and elevated. Older males. Can prog to CA.
Bowenoid papulosis - Young men, usually doesn't prog to CA.
Bowenoid papulosis is...
indolent
Malignant carcinomas
squamous cell carcinoma and verrucous carcinoma
Squamous cell CA
Most common CA of the penis.
Often due to HPV 16 and 18 (high risk viruses)
Ulcerated mass.
Micro - keratinization and keratin pearl formation
Extensive local spread and infiltrative lymph spread
Verrucous carcinoma
Large, broad throngs from epithelium and invades in a pushing manner.

Grows locally and does not metastasize. Very well-differentiated.

Some may be associated with HPV types 6 and 11.
Fournier's gangrene
Of the scrotum

idiopathic necrotizing fasciitis
Medical emergency often in immunesupp and diabetics.
Tumors of scrotum
Benign - Cysts
Malignant - Squamous cell CA (linked to chimney sweeps). Hygeine is key.
Polycyclic hydrocarbons found to be potent carcinogens.
Testis and epididyms congenital issues
Cryptorchidism (undescended testis)
Usually swollen inguinal region, but can be be abdomen.
Often due to anatomic anomalies, hormone issues (HPA axis), dysgenesis...
1/4 are bilateral
Can result in atrophy, trauma infertility, cancer (even in the descended testis).

CA risk increases with distance from scortum and orchiopexy can decrease the risk (moving the testis into the scrotum)

Sertoli cells and spermatogonia predominate (seminiferous tubules).
Germ cells arrested in development.
Marked hyalinization and thickening of the basement membrane of the spermatic tubules.

Testes are small and fibrotic
