|
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) |
|

|
Pseudoepitheliomatous hyperplasia
Donovan bodies - Use Giamsa stain. Minute encapsulated organisms in macrophages |
|

|
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
|

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) |
|
Micro view of cryptorchidism
|
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 |
|
Infertility and cryptorchidism
|
If bilateral, more like to be infertile.
Age of orchioplexy may influence fertility. (before age 4 is important) |
|

|
|
Which is more frequent - epididymitis or orchitis?
|
epedidymitis
|
|
Testis/epididymis non-spec infections
|
Childhood - gram - rods associated with genitourinary abnormalities
Young adult - sexually transmitted (chlamydia or gonorrheoeae) OLder adults - EColi or pseudomonas |
|

|
Gonorrhea - urethra to prostate to seminal vesicles to epididymis
Mumps - Orchitis is rare in children. Unilateral most commonly. With bilateral, more common to have infertilit (infarcts) TB - After infections higher in GU tract (from epididymis to testis) Syphilis - from testis to epididymis. Inflamm and endarteritis or gumma. |
