Penis/Scrotum Path Flashcards
hypospadias+ defect
epidspadias
abrnormal opening on ventral penis
dorsal side (defect in genital tubercle)
(failure of urethral fold closure)
phimosis
orifice of prepuce too small to retract
due to scarring from primary infection
blanitis
inflammation/infection of glans
blanoposthisis
inflammation / infection of glans and prepuce
Balanitis Xerotica Obliterans
thinning of epidermis
glassy, acellular appearance
band of inflammation > lymphocytes
increased keratine
Bowens diseae (leukoplakia)
association
squamous cell carcinoma in situ,
shaft of penis+scrotum
patients >35
HPV type 16+18
Erythroplasia of Queyrat
association
squamous carcinoma in situ
redless located on mucosal surface of glans and prepuce
HPV type 16
precursor for invasive squamous cell carcinoma
Bowenoid papulosis
assocations
squamous cell carcinoma in situ
multpiple, pigmented reddish brown papules
HPV 16
does NOT develop into invasive cell squamous carcinoma (no posibility of invasion)
most common cancer of Penis
most common sites
invasive squamous cell carcinoma
glans or mucosal surface of prepuce
risk factors for invasive sqaumous cell carcinoma of the penis
HPV 16, 18
smoking
Lack of circumcision
Greatest risk factor = bowen’s disease, erythroplasia of queyrat)
invasive sqaumous cell carcinoma metastasizes to
inguinal and iliac nodes
blockage of ___ renal vein can cause variocele
left renal vein (right spermatic vein dains to IVC)
hydrocele fluid accumulates in
treatment
tunica vaginalis
treatment - hydrocelectomy - removal of TV
