1) Cervical Carcinoma
CIN is the potentially premalignant transformation andabnormal growth (dysplasia) of squamous cells on the
surface of the cervix.
Almost all carcinomas arise in CIN; but not all cases of CIN
progress to carcinoma.
Three grades:
CIN I: mild dysplasia CIN II: moderate dysplasia
CIN III: severe dysplasia
The higher the grade, the more likely the lesion will progress
to carcinoma.
Cervical intraepithelial neoplasia (CIN)

Cervical Carcinoma
Persistent infection with high-risk HPV
integrate into genome, inactivate p53, RB Early age at first intercourse
Multiple sexual partners
A male partner with multiple previous partners

Cervical Carcinoma
Most cases are squamous, arising from CIN
Peak age: 45 (10-15 years after CIN develops!)
Spreads slowly
Mortality is related to stage:
stage 0 (preinvasive): 100% 5 year survival
stage 4: 10% 5 year survival

2) Endometriosis
A medical condition in which endometrial like cells
appear and flourish in areas outside the uterine cavity.
These endometrial-like cells in areas outside the uterus
are influenced by hormonal changes and respondsimilarly as do those cells found inside the uterus.
Endometrium undergoes cyclic bleeding
Causes scarring, pain, sometimes sterility.
How does endometrium get out?

Endometriosis in ovary (chocolate cyst)
7/30/2019 Lecture Reproductive System

Endometrial Hyperplasia
Proliferation of endometrium due to estrogen excess
Risk factors: anovulatory cycles, obesity, estrogen-
producing ovarian tumors, exogenous hormone use
Three categories: simple, complex, and atypical
The more severe the hyperplasia, the greater the
chance that it will evolve into carcinoma

Breast
Many breast diseases present as lumps
Most lumps represent benign things, howeverit still needs to be evaluated
Ultrasound, mammography, fine needleaspiration, and biopsy are the usual methods
7/30/2019 Lecture Reproductive System

Age
Family History
Increased estrogen exposure
Obesity
Alcohol consumption
High-fat diet
7/30/2019 Lecture Reproductive System

Breast Carcinoma
5-10% of all cases are hereditary
Worry if first degree relative with breast cancer Most have BRCA-1 or BRCA-2 mutations

Breast Carcinoma
Neoplastic cells fill ducts (DCIS) or lobules (LCIS) but donot breach basement membrane
Incidence has increased with mammography
If untreated, over 1/3 will develop invasive carcinoma
With treatment, prognosis is excellent
Non-Invasive Breast Carcinoma
Ductal (or not otherwise specified) carcinoma, lobular
carcinoma
Inflammatory carcinoma - breast looking red and swollen.Often does not present with a lump, often not detected by
mammography or ultrasound.

1) Testis: Cryptorchidism
Incomplete testicular descent into scrotum
Present in 3% of newborns; most descend by 6
months.
Associated with sterility and malignancy
Orchiopexy - move an undescended testicle
into the scrotum and permanently fix it there

2) Testis: Neoplasms
The most common cancer in men aged 15-35
5 cases per 100,00 males
Firm, painless enlargement of the testis
Seminomas and non-seminomas
Some present with metastases Treatable curable! - if detected early
7/30/2019 Lecture Reproductive System
60/99
Testis: Neoplasms
Small, painless lump
Enlarged testicle
Feeling of heaviness intesticle or groin
Change in the way thetesticle feels
Accumulation of fluid
Testicular self-examination
7/30/2019 Lecture Reproductive System
61/99
Testis: Neoplasms
7/30/2019 Lecture Reproductive System
62/99
Testis: Neoplasms
Half of all testicular cancers
Seminomas develop from the sperm-producing germ cellsof the testicle.
Arise from germinal epithelium of seminiferous tubules
Tumor classification - i) Seminoma
7/30/2019 Lecture Reproductive System

Seminoma
7/30/2019 Lecture Reproductive System

Embryonal tumor (undifferentiated stem cells)
Yolk sac tumor (yolk sac cells) Choriocarcinoma (immature placental cells)
Teratoma (somatic tissue cells)
ii) Nonseminomas

Teratoma
7/30/2019 Lecture Reproductive System
70/99
Testis: Neoplasms
Important for staging and follow-up.
Human chorionic gonadotropin (hCG) Normally made by placental cells
in choriocarcinoma; sometimes in seminoma
Alpha-fetoprotein (AFP)
Normally made by fetal yolk sac and other cells in yolk sac tumors and embryonal carcinoma
Tumor markers

71/99
Testis: Neoplasms
Overall, prognosis is good If detected early, 90% cure rate
8000 new cases a year, only 400 deaths.
Seminomas Often remain localized until large Metastasize locally first, then later, distantly
VERY sensitive to radiation and chemotherapy Nonseminomas
Metastasize earlier, farther Worse prognosis

At age 25 (in 1996), diagnosed with aggressive
testicular cancer Already metastatic to brain, abdomen, lungs
Treated with surgery, chemotherapy
Victories in 1999-2005 Tours de France!

Prostate
7/30/2019 Lecture Reproductive System
75/99
4) Prostate: Nodular Hyperplasia
Very common! 90% of men have it by their 70s.
Caused by excessive androgens
Benign proliferation of glands and stroma Large
prostate
Usually affects central zone of the prostate
Symptoms (in 10% of patients): hesitancy, urgency,nocturia, poor urinary stream.
Symptoms of urinary obstruction
Cause: excessive androgen stimulation

5) Prostate: Carcinoma
Common, deadly cancer
Early on asymptomatic, detected by PSA test
Later: hard nodule by rectal exam
Much later: local pain and obstructive symptoms
Develops in peripheral zones of prostate
Peak incidence: 65-75
Treatment, prognosis depend on stage, grade
Some come to attention because of metastases

Prostatic carcinoma

Prostate: Carcinoma
Enzyme made by prostatic epithelial cells
Malignant cells make more PSA than benign cells Used as a screening and monitoring test
PSA 10 suggests cancer
But PSA can go up in benign disorders too (nodularhyperplasia, prostatitis)!
So: elevated PSA doesnt always mean cancer.
Prostate-specific antigen (PSA)
7/30/2019 Lecture Reproductive System

Prostate: Carcinoma
Hormonal influences males castrated before puberty dont get it
treatment with orchiectomy/estrogens works
Genetic contributions increased risk in first-degree relatives earlier onset in blacks
Environmental influences in Scandinavian countries, in Asia
Cause
7/30/2019 Lecture Reproductive System
85/99
Prostate: Carcinoma
Prognosis depends on stage (and grade)
Treatment: surgery, radiation, hormonal therapy
Limited disease: 90% survive 10+ years
Metastatic disease: 10-40% survive 10+ years
