Prostate Gland Flashcards
Below the prostate, the epithelium is…
Stratified or Pseudostratified columnar epithelium
Difference in hypo and epispadias
Hypo – Ventral
Epi – Dorsal
Problem with hypo and epispadias
Associated with failure of descent of testis
Predispose to infections, obstruction
May cause sterility –> diverticula or cyst
What is phimosis?
Opening of the prepuce too small to permit normal retraction of the penis. Interferes with cleanliness and permits accumulation to secretions and debris
What is paraphimosis
Constriction of glans penus following forced retraction of a phimotic prepuce. Swelling and urethral obstruction with retention.
What is balanoposthitis
Nonspecific infection of the glans and prepuce
Usually Candida, anerobes, gardnerella
HPV is associated with…
Chondylomata acuminata
Intraepithelial neoplasm
What is condyloma acuminatum
Benign neoplasm related to common wart
Gross presentation of condyloma acuminatum
On moist mucocutaneous surfaces of external genetalia
Red Papillary Masses
If present in children suspect sexual abuse
Microscopic presentation of condyloma acuminatum
Papila composed of connective cores covered by well differentiated hyperplastic epithelium. Does not pepetrate basement membrane.
Names of carcinoma insitu of the penis
Bowen’s disease
erythrolasia of Queyrat
Bowenoid papulosis
Important details about squamous cell carcinoma of the penis
50% HPV related
Gross – glans or inner prepuce, paque-like lesion progressing to an ulcer or mass
Behavior – Slow growing, invasive, destructive
Testes not on this test…maybe look at it or whatever
I’m not your mom
Three types of prostatitis
Acute bacterial
Chronic bacterial
Chronic abacterial
How to identify bacterial vs abacterial prostatitis
Bac should have more than 15 WBC/hpf in prostatic secretions
Bacterial growth in secretions
Important details on Acute Bacterial Prostatis
Suppurative Inflammation
Usually E Coli, G-, or staph from urine reflux
Fever, Chills, Dysuria
Prostate Tender, Soft
Important details on chronic bacterial prostatis
Asymptomatic OR dysuria, lower back pain, perianal/suprapubic pain, recurrent cystitis/urethritis
Important features of chronic abacterial prostatitis
Most common form, unknown etiology
Symptoms like chronic bacterial, but with no history or recurrent UTI
BPH nodules originate in the ___ area of the nodule
Inner periurethral area of middle and lateral lobes
Microscopic details of BPH
Glandular hyperplasia, glandular dilation, stromal hyperplasia.
Pink, Loose glandular tissue and gray, firm fibromuscular tissue
Symptoms of BPH
Urethral obstruction and urine retention
Dysuria, Troble stopping/starting/dribbling
Cystitis
Important risk factors for Prostatic Carcinoma
Age over 50
Blacks>whites»asians
Hormonal Factors
Gross presentation of Prostatic Carcinoma
Usually begins in periphery
Gritty and Firm on Palpation
Local invasion/Metastasis
Microscopic presentation of Prostatic Carcinoma
Well defined, small, irregularly shaped glands
Glands lines with single layer of cuboidal
Randomly Distributed/Crowded
Often have foci of ductal acinar dysplasia
