Study Notes
Female Genital Diseases - Uterine Disorders
- Uterine anomalies occur in less than 5% of women, but are seen in up to 25% of women with miscarriages or premature births.
- Types of uterine anomalies include:
- Didelphys: the two halves of the uterus remain separate.
- Arcuate: a uterus with an indentation on the top part.
- Unicornuate: only one half of the uterus develops.
- Bicornuate: a heart-shaped uterus.
- Septate: uterus with a partition in the middle.
Disorders of the Uterine Body
- Abnormal uterine bleeding: These terms are crucial.
- Dysfunctional uterine bleeding: bleeding without underlying structural problems, often caused by hormonal imbalances during the menstrual cycle.
- Menorrhagia: excessive and prolonged bleeding during menstruation.
- Metrorrhagia: bleeding between periods.
Organic Causes of Uterine Bleeding
- Pregnancy complications (abortion, trophoblastic disease, ectopic pregnancy).
- Infections (cervicitis, endometritis).
- Tumors (leiomyoma, endometrial polyps, cervical cancer).
- Blood disorders.
Non-Organic (Hormonal) Causes of Dysfunctional Uterine Bleeding
- Hyper-estrogenic states with anovulation, such as polycystic ovarian disease, cortical stromal hyperplasia, and functioning ovarian tumors.
- Other systemic endocrine disorders (thyroid or adrenal diseases, pituitary tumors).
Inflammation of the Endometrium (Endometritis)
- Acute endometritis: often caused by gonorrhea or puerperal sepsis.
- Chronic endometritis:
- Chlamydia and other intrauterine infections.
- Post-abortion or partial abortion, due to retained gestational tissue.
- Intrauterine contraceptive devices.
- Endometrial tuberculosis (granulomatous).
Endometriosis and Adenomyosis
- Endometriosis: endometrial glands or stroma in abnormal locations outside the uterus (ovaries, ligaments, peritoneum, etc.).
- Adenomyosis: endometrial tissue within the uterine muscle, causing uterine enlargement and irregular thickening.
Endometrial Polyps
- Sessile mass composed of endometrial glands and stroma.
- Benign, but can occasionally show endometrial hyperplasia or cancerous changes.
Endometrial Hyperplasia
- Characterized by glandular and stromal proliferation.
- Results from prolonged high estrogen levels (Stein-Leventhal syndrome, granulosa and theca cell tumors, estrogen therapy).
Types of Endometrial Hyperplasia
- Simple hyperplasia (cystic glandular hyperplasia): glands with cystic dilatation.
- Complex hyperplasia without atypia: crowded glands with no cytologic changes.
- Complex hyperplasia with atypia (EIN): crowded glands with cytologic changes.
Carcinoma of the Endometrium
- Peak incidence in women aged 55-65 (post-menopause).
- Less common than cervical cancer.
- Risk factors: obesity, diabetes, infertility, endometrial hyperplasia, and hyperestrogenemia.
Morphology (Gross) of Endometrial Carcinoma
- Localized polypoid tumor.
- Diffuse spreading lesion.
Morphology (Microscopic) of Endometrial Carcinoma
- Well-differentiated adenocarcinoma (e.g., endometrioid, with squamous, secretory, or mucinous differentiation).
- Poorly differentiated carcinoma (e.g., clear cell carcinoma, papillary serous carcinoma).
Clinical Features of Endometrial Carcinoma
- Abnormal uterine bleeding.
- Abnormal Pap smear.
Prognosis of Endometrial Carcinoma
- Good in localised well-differentiated tumors.
- Poor in spreading or poorly differentiated tumors.
Malignant Mixed Mesodermal Tumors
- Rare tumors derived from primitive stromal cells in post-menopausal women.
- Gross: bulky, protrude into endometrial cavity and vagina, polypoid.
- Microscopic: glandular structures and stromal sarcomatous elements (muscle, cartilage, osteoid tissue).
- Prognosis: highly malignant, with a 5-year survival rate of 25%.
Tumors of the Myometrium (Leiomyomas)
- Leiomyomas (fibroids): most common uterine tumor in women aged 30-50, related to estrogen stimulation.
- Types of myomas:
- Intramural: within the uterine wall.
- Subserous: grows outwards.
- Submucosal: beneath the endometrium.
- Cervical: in the cervix.
Morphology of Leiomyomas (Gross)
- Enlarged uterus, irregular, multiple myomas.
- Round, firm, gray-white masses, well-circumscribed, with whorl appearance.
Morphology of Leiomyomas (Microscopic)
- Interlacing bundles of smooth muscle fibers and fibrous tissue.
- Mitotic figures are few.
Effects and Complications of Myomas
- Menorrhagia or metrorrhagia (excessive bleeding).
- Pressure on bladder causing micturition frequency.
- Infertility.
- Degenerations (hyaline, red, cystic, necrosis).
- Malignant change is rare (leiomyosarcoma).
Leiomyosarcoma
- Uncommon tumor, forms bulky, fleshy masses in the uterine wall.
- Microscopic: fascicles of eosinophilic spindled cells with blunt-ended nuclei, showing variable pleomorphism, presence of 10 mitoses per 10 high-power fields.
- Aggressive, widespread dissemination, with a 5-year survival rate of 40%.
Diseases of the Fallopian Tubes
- Inflammation (salpingitis):
- Suppurative salpingitis: infection with pyogenic organisms (e.g., streptococci, staphylococci, gonococci).
- Tuberculous salpingitis: hematogenous spread of tuberculosis, or associated with tuberculous endometritis.
- Effects of inflammation: fibrosis, which can cause infertility (if bilateral).
Tumors of the Fallopian Tubes
- Rare.
- Adenocarcinoma: usually arises in the fimbriated portion of the tube.
- Ectopic (tubal) pregnancy: implantation of the fertilized ovum outside the uterine cavity (in the fallopian tube), which can rupture causing hemorrhage.
