  1. What are the most common types of penile diseases?
    STD
  2. Penile tumors: there are two types of benign tumors of the penis related to HPV.
    what are they called?
    what are the common HPV strains that cause them?
    • condyloma acuminatum: grow to the outside.
    • giant condyloma: grow on the inside.
    • 6 and 11 (low risk types of HPV)

    • squamous type of epithelia with changes in the epithelia. both appear the same, but one grows outside while other grows in.
    • TREAT: excise them.
  3. Dysplastic changes in penis are rare.
    Men don't get them as frequently as women do.
    What type of HPV are they associated with?
    • HPV 16.
    • there are three types: tissue under microscope looks the same. FULL THICKNESS DYSPLASIA
  4. Bowen's disease. squamous carcinoma in situ
    • 1. patch of sore tissue on penis and scrotum.
    • associated with visceral malignancy.
    • carcinoma in situ: MAY BECOME SQ. CELL CARCINOMA W/O TREATMENT
  5. erythroplasia of quevrat
    • occurs in glans and prepuse.
    • is an erythematous patch (reddish patch).
    • carcinoma in situ: MAY BECOME SQ. CELL CARCINOMA W/O TREATMENT
    • not associated with visceral malignancy.
  6. Bowenoid papulosis:
    • small pappilar lesion on surface of scrotum.
    • slightly darker in color.
    • carcinoma in situ: MAY BECOME SQ. CELL CARCINOMA W/O TREATMENT
  7. Squamous cell carcinoma of the penis.
    what types of HPV is it associated with?
    • not very common.
    • slow growing malignancy.
    • Related to HPV (16 and 18)
  8. What types of diseases affect the epidymus?
    gonorrhea and TB.
  9. What type of disease affects testicles?
    syphilis.
  10. Children with GI abnormalities are more prone to getting infected with what type of bacti?
    • gram negative rods.
    • e-coli and pseudomonas.
  11. in men under 35, the common cause of STD is/are?
    chlamydia, trachomatis, and neisseria gonorrhea.
  12. over 35 commonly associated with Inflammation occurs in?
    • E.coli
    • bacterial infections cause acute inflammation of testes and epididymes --> fibrous scarring and infertility.
  13. Mumps and inflammation?
    • 20% of males who get mumps after 10 years old, you may get mumps orchitis.
    • often unilateral and interstitial
    • does not result in infertility (usu)
  14. What is cryptorchidism?
    • undescended testes.
    • can be corrected after birth.
    • most are unilateral
  15. why is cryptorchidism significant?
    • 1. may lead to infertility (heat)
    • 2. may increase trauma (crush against ligaments and bone)
    • 3. 10-40 fold greater risk in developing cancer.
  16. testicular tumors.
    not very common.
    what are the 2 types?
    • 1. germ cell tumors (95%)
    • 2. non-germ cell tumors
  17. what are the two types of germ cell tumors?
    seminomatous and non-seminomatous type.

    • seminomatous type: composed of seminomas.
    • if they're treated quickly, they're fine, patient does well.

    non-seminomatous: are very aggressive!
  18. non-germ cell tumors
    • mostly benign.
    • arise from leydig cells or sertoli cells.
  19. What is the most common germ cell tumor?
    • seminomas.
    • occurs from 15-35 year old.
    • most common, accounts for 10% of death.
    • most are benign.
  20. Prostatitis: inflamation of the prostate.
    can be acute or chronic.
    acute prostatis: commonly has neutrophils.

    chronic: has lymphocytes and plasma cells.

    most common cause if UTI is E.coli.
  21. Second most common condition in older men is:
    Benign prostatic hyperplasia
    • hyperplastic tissue grows in nodules, and prefers area around urethra, obstructing it.
    • this translates to ==> interrupted urinary flow.
    • is not pre-malignant at all.
  22. Prostatic carcinoma
    • 60% chance of prostate cancer in older men.
    • prostate and lung cancer are two most common cancers in men.
    • location of carcinoma occurs in perpihery: so asymptomatic.
    • once there are symptoms: usually high stage carcinoma, survival rate is very low.
