– D&C +/- Hysteroscopy
Most frequent pelvic tumors?
Leiomyoma
Leiomyoma - Pathology?
– Benign neoplasm arising from monoclonal population of smooth muscle cells
– Growth stimulated by estrogen
also…
- They can arise in the myometrium (intramural), project into the endometrium (submucous), or project out along the serosa (subserosal).
- They can also be found in the cervix, round ligament, broad ligament or fallopian tube.
Leiomyoma - Incidence in Caucasian vs. African-American women?
– 25% Caucasian women
– 50% African American women
Leiomyoma - Symptoms?
– Most asymptomatic
– Dysmenorrhea, menorrhagia, intermenstrual bleeding
– Infertility, recurrent miscarriage
– Pelvic pressure; acute pain with degeneration
– Urinary frequency
– Dyspareunia
What is “dyspareunia”?
Painful sexual intercourse
Leiomyoma - Diagnosis?
– Physical examination
– Ultrasound
– CT scan or MRI
Leiomyoma uteri - Tx?
• Observation
• Hormonal therapy
– Pseudomenopause with GnRH agonists (leuprolide acetate, goserelin acetate, nafarelin acetate)
• Surgery (myomectomy, hysterectomy)
• Uterine artery embolization (UAE) (causes pain, which is managed w/ NSAIDS)
• MR guided focused ultrasound
Adeonmyosis - Pathology?
Endometrial stoma and glands within the myometrium
Adenomyosis - Incidence & Age group?
– May be present in as many as 60% of uteri
– Usually in women over age 40
Adenomyosis - Symptoms?
– Asymptomatic
– Dysmenorrhea
– Metrorrhagia, dyschezia, dyspareunia
Adenomyosis - Dx?
– Physical exam
– Hysteroscopy; Hysterogram; MRI
– Hysterectomy
**Dx is made pathologically following hysterectomy
Adenomyosis - Tx (management)?
– GnRH agonists, cyclic hormones, progesterone releasing IUD
– Hysterectomy
Endometrial Hyperplasia - Symptoms?
– None
– Intermenstrual bleeding or spotting
– Metrorrhagia/Menorrhagia
– Postmenopausal bleeding or spotting
Endometrial Hyperplasia - Dx?
– Endometrial biopsy D&C
– D&C/Hysteroscopy
Endometrial Hyperplasia - Cause?
Unopposed estrogen stimulation causes excessive proliferation of the glandular portion of the endometrium
- Anovulatory cycle
- Inc’d aromatization of androgens in obese patients
(progesterone normally counteracts these proliferative effects, leading to stabilization and thinning of the endometrial lining)
Endometrial Hyperplasia - Tx?
• Hormonal Therapy:
– Medroxyprogesterone acetate (Provera)
– Hydroxyprogesterone (Delautin)
– Progesterone IUD (Mirena)
• Hysterectomy
Endometrial Carcinoma - Sx?
- Postmenopausal bleeding or spotting
- Clear or purulent vaginal discharge
- Intermenstrual spotting
- Menorrhagia/Metrorrhagia
Endometrial Carcinoma - Dx?
- Sampling the uterine lining:
- Endometrial biopsy
- Dilation and Curettage (D&C)
- Hysteroscopy
Endometrioid endometrial cancer is divided into Type 1 and Type 2.
What does the “Type” indicate?
Which type is more likely to recur?
Which type is more likely to have distant metastatic spread?
Type 1 is estrogen dependent.
Type 2 is not estrogen dependent & is more likely to have distant metastatic spread and to recur
Uterine Sarcoma vs. Endometrial Adenocarcinoma:
Which is more aggressive?
Which is more common?
Which are more common in blacks vs. whites?
Uterine Sarcoma:
- More aggressive
- Less common
- Women more likely to be African-American
Endometrial Adenocarcinoma:
- Less aggressive

- Black women have less risk of developing
Uterine Sarcoma - Tx?
- Total abdominal hysterectomy
- Radiation may be considered to reduce the incidence of pelvic recurrence
- Chemotherapy as adjuvant therapy is under clinical investigation
- Chemotherapy may be used as palliative therapy
