Benign Diseases of the Female Reproductive Tract II

by SMC OBGY R1 Choi, Suk Joo

II. Pelvic Mass

C. Reproductive Age Group

1. Differential Diagnosis
- Age is important determinant of the likelihood of malignancy

2. Uterine Mass

1) Uterine Leiomyomas

a. At least 20% of all women of reproductive age and may be discovered incidentally during routine annual examination
b. Asymptomatic fibroids may be present in 40-50% of women older than 40 years of age
c. Fewer than one-half of uterine leiomyomas produced symptoms.
d. Each leiomyomas arises from a single neoplastic cell within the smooth muscle of the myometrium
e. Fibroids have the potential to enlarge during pregnancy as well as to regress after menopause
f. Fibroids are discrete nodular tumors that vary in size
g. Degenerative changes are reported in approximately 2/3 of all specimens

i) During pregnancy of in women taking progestational agents
ii) With necrosis
iii) As a “smooth muscle tumor of uncertain malignant potential”

h. Studies suggest that malignant degeneration of a preexisting leiomyoma is extremely uncommon, occurring in less than 0.5%

i. Symptoms

i) menorrhagia
ii) chronic pelvic pain (dysmenorrhea, dyspareunia, pelvic pressure)
iii) acute pain from torsion of a pedunculated leiomyomas or infarction
iv) urinary sx. ? frequency, partial ureteral obstruction, complete urethral obstruction
j. Leiomyomas are an infrequent primary cause of infertility and have been reported as a sole cause in less than 3% of infertile patients
k. Symptoms infrequently associated

i) Rectosigmoid compression
ii) Prolapse of a pedunculated submucous tumor through the cervix
iii) Venous stasis of the lower extremities and possible thrombophlebitis
iv) Polycythemia
v) Ascites

3. Ovarian Masses

a. About 2/3 of ovarian tumors are encounted during the reproductive years
b. Most ovarian tumor(80-85%) are benign, 2/3 of this tumors occur between 20-44yr
c. The chance that a primary ovarian tumor is malignant in a patient younger than 45 years of age is less than 1 in 15
d. The most common symptoms : abdominal distension, abdominal pain or discomfort,lower abdominal pressure sensation, urinary and GI Sx
e. If the tumor is hormonally active, symptoms of hormonal imbalance (vaginal bleeding related to estrogen production)
f. Acute pain occur with adnexal torsion, cyst rupture, or bleeding into a cyst.
g. DDx between benign and malignancy

i) Mass that unilateral, cystic, mobile, smooth are most likely to be benign
ii) Mass that bilateral, solid, fixed, irregular and associated with ascites, cul-de-sac nodule, and a rapid growth are more likely to be malignant.

1) Nonneoplastic Ovarian Mass
: - Benign and usually do not cause sx. or require surgical management.
- Combination monophasic OC Tx reduce the risk of functional ovarian cysts .
- Triphasic OC therapy increased the risk.
- Smokers have a twofold increased risk.

a. Follicular Cysts

: The most common functional cyst, which is rarely larger than 8cm

b. Corpus Luteum Cysts

: Less common than follicular cysts, and called cyst when its diameter is greater than 3cm
Halban syndrome which simulated ectopic pregnancy ? persistent corpus luteum cyst
If ruptured, leading to a hemoperitoneum and require a surgical management

c. Theca Lutein Cysts

: The least common
Bilateral and occur during preg. (including molar preg.)
1/4 of molar preg and 10% of choriocarcinoma may be associated
Association with multiple gestations, DM, Rh sensitization,
clomiphen citrate and human menopausal gonadotropin /
human chorionic gonadotropin ovulation induction,
the use of GnRH analogs

2) Other Benign Masses

a. Endometriosis
b. Polycystic Ovaries

: Originally considered the sine qua non of PCOS
22% of general population
Evaluate hyperandrogenism and chronic anovulation as well as
polycystic ovaries

3) Neoplastic Masses

- More than 80% of benign cystic teratomas(dermoid cysts) occur during the
reproductive age
- More than 3/4 of malignant transformation occur older than 40 years of age
- The risk of torsion with dermoid cysts is 15% and it occur more frequently
than with ovarian tumors in general (d/t high fat content, “float”)
- An ovarian cystectomy is almost always possible
- Preserving a small amount of ovarian cortex in a young pt. with a benign
lesion is preferable to the loss of the entire ovary
- The risk of epithelial tumors increases with age

a. Cystic Teratoma
: Most common (66%) benign tumors in women < 40yr

b. Serous Tumors

: Generally benign, 5-10% have borderline malignant potential,
20-25% are malignant.

c. Benign Mucinous Tumors

: Typically have a lobulated, smooth surface
5-10% of mucinous ovarian tumors are malignant
-> DDx with metastatic GI tumors
d. Others : fibroma, Brenner tumor, mixed forms of tumor

4) Other Adnexal Masses

a. Ectopic pregnancies
b. Paraovarian cyst

4. Diagnosis

1) Complete pelvic exam (rectovaginal exam, Pap test)
-> Estimation in centimeters

2) Other studies

a. Endometrial sampling with an endometrial biopsy or D&C
b. Urinary tract studies (cystometric measurements)
c. Cystoscopy
d. USG or IVP

3) Labaratory studies

a. Pregnancy test, Pap test, CBC, ESR, Stool test, Tumor marker (e.g. CA 125)
b. A number of benign conditions (Ut. myoma, PID, pregnancy, ES) can elevate
CA125, and thus lead to unnecessary surgical intervention
4) Imaging studies
a. USG : transvaginal of transabdominal
b. CT
c. Abdominal flat plate X-ray : calcification
d. Hysteroscopy
e. HSG
f. MRI : most useful in the Dx. of uterine anomalies

5. Management

1) Management of Leiomyomas

a. Nonsurgical

- Judicious pt. observation and F/U are indicated primarily intervention is
reserved for specific indications and Sx.
- Use of GnRH agonist 40-60% decrease in uterine volume
- Hypoestrogenism results from treatment and associated with reversible bone
loss and Sx.
- Ix. of GnRH agonist

i) Preservation of fertility in women with large myoma before attempting
conception, or preoprerative treatment before myomectomy
ii) Treatment of anemia to allow recovery of normal hemoglobin levels
before surgical management, minimizing the need for transfusion or
allowing autologous blood donation.
iii) Treatment of women approaching menopause in an effort to avoid surgery
iv) Preoperative treatment of large myomas to make vaginal hysterectomy,
hysteroscopic resection or ablation or laparoscopic destruction more
feasible
v) Treatment of women with medical contraindication to surgery
vi) Treatment of women with personal or medical indications for delaying
surgery

b. Surgical
- Indication
i) Abnormal uterine bleeding with resultant anemia, unresponsive to
hormonal management
ii) Chronic pain with severe dysmenorrhea, dyspareunia, or lower
abdominal pressure or pain
iii) Acute pain as in torsion of a pedunculated myoma or prolapsing
submucosal fibroid
iv) Urinary symptoms or sign such as hydronephrosis after complete
evaluation
v) Rapid enlargement of the uterus during the premenopausal years, or
any increase in uterine size in a postmenopausal woman, because of
inability to exclude a uterine sarcoma
vi) Infertility with leiomyomas as the only abnormal finding
vii) Enlarged uterine size with compression sx. or discomfort.

- Hysterectomy
- Abdominal myomectomy
- Vaginal myomectomy
- Hysteroscopic resection

2) Management of Ovarian Masses

a. OC are effective in leading to resolution of functional ovarian cysts
b. OC are effective in reducing the risk of subsequent ovarian cysts.
c. Symptomatic cysts should be evaluated promptly, although mildly
symptomatic masses suspected to be functional can be managed with
analgesics rather than surgery.
d. Surgical intervention in significant pain or the suspicion of malignancy
e. Malignancy : on USG large cysts, multiloculations, septa, papillae,
increased blood flow
f. In suspicion of a malignant cyst : at any age, explorative laparotomy
should be done promptly
g. Laparoscopic surgery should be reserved for diagnostic or therapeutic
purposes for pt at very low risk for malignancy

D. Postmenopausal Age Group

Ovarian Size

- Before menopause, 3.5 X 2 X 1.5 cm
- In early menopause 2 X 1.5 X 0.5 cm
- In late menopause 1.5 X 0.75 X 0.5 cm

1. Differential Diagnosis

1) Ovarian Masses

a. Postmenopausal palpable ovary (PMPO) syndrome
b. The incidence of ovarian cancer increases with age and is predominantly
a disease of postmenopausal women : the average patient age is 61 years
c. Asymptomatic, small (<5cm in diameter), unilocular, thin-walled cyst
: the risk of malignancy is extremely low and follow the conservative
therapy without surgery
d. Indication of surgery
i) Adverse pedigree with a strong family history of ovarian, breast,
endometrial, colon cancer
ii) Mass appears to be enlarging
e. The risk of malignancy for pelvic mass : 50%

2) Uterine and Other Masses
a. Paraovarian cysts and unusual tumors such as benign retroperitoneal
cytst of mullerian type
