Abnormal Uterine Bleeding:
Differential Diagnosis
(In a Page: Signs and Symptoms)
- Endometrial hyperplasia
–Endogenous estrogen excess (e.g., obesity,
tumor)
–Exogenous estrogen
–DUB is a diagnosis of exclusion (usually
not cyclic, occurs irregularly throughout the menstrual cycle)
-
Polycystic ovarian syndrome
-
Hypo- or hyperthyroidism
-
Endometrial atrophy
–Caused by long-term progestin or oral contraceptive use
-
Anatomic or structural lesions
–Uterine leiomyoma (fibroids)
–Foreign body (often intrauterine device)
–Cervical or uterine polyps
-
Pelvic infection (cervicitis, pelvic inflammatory disease)
-
Hypothalamic lesion
-
Hyperprolactinemia
-
Medications (e.g., exogenous estrogen, phenothiazines, reserpine)
-
Coagulation disorders
–Platelet dysfunction: Thrombocytopenia, leukemia, medications (e.g., aspirin, NSAIDs)
–Clotting factor abnormality: Von Willebrand's disease, hemophilia, hepatic or renal disease, anticoagulant use
-
Complications of pregnancy
–Spontaneous abortion (miscarriage)
–Ectopic pregnancy
–Placenta previa
–Placental abruption
-
Endometrial cancer
–Risk factors include older age, chronic anovulation, obesity, hypertension, DM, and unopposed estrogen
-
Systemic disease (e.g., HIV, hepatic disease, renal disease)
-
Nonuterine bleeding
–Vaginal (tear, trauma, or cancer)
–Cervical (trauma or cancer)
–Urinary (UTI or cancer)
–Rectal (bleeding, trauma, fissure, or cancer)
-
Other malignancy (ovarian or uterine tumor, sarcoma)
-
Endometrioma

Cervical cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Although the cause is unknown, several predisposing factors have been related to the development of cervical cancer: frequent intercourse at a young age (younger than age 16), multiple sexual partners, multiple pregnancies, exposure to sexually transmitted diseases (particularly genital human papillomavirus), and smoking.
In almost all cases of cervical cancer (95%), the histologic type is squamous cell cancer, which varies from well-differentiated cells to highly anaplastic spindle cells. Only 5% are adenocarcinomas. Usually, invasive cancer occurs between ages 30 and 50; rarely, in patients younger than age 20.
In 2000, 12,800 women were diagnosed with cervical cancer and there were 4,600 deaths from this disease.

Dysfunctional uterine bleeding:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
DUB usually results from an imbalance in the hormonal-endometrial relationship, where persistent and unopposed stimulation of the endometrium by estrogen occurs. Disorders that cause sustained high estrogen levels are polycystic ovary syndrome, obesity, immaturity of the hypothalamic-pituitary-ovarian mechanism (in postpubertal teenagers), and anovulation (in women in their late 30s or early 40s).
In most cases of DUB, the endometrium shows no pathologic changes. However, in chronic unopposed estrogen stimulation (as from a hormone-producing ovarian tumor), the endometrium may show hyperplastic or malignant changes. DUB occurs in 20% of adolescents and in 40% of women older than age 40.

Uterine cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Uterine cancer seems linked to several predisposing factors:
❑abnormal uterine bleeding
❑diabetes
❑familial tendency
❑history of uterine polyps or endometrial hyperplasia
❑hypertension
❑low fertility index and anovulation
❑nulliparity
❑obesity
❑uninterrupted estrogen stimulation.
In most cases, uterine cancer is an adenocarcinoma that metastasizes late, usually from the endometrium to the cervix, ovaries, fallopian tubes, and other peritoneal structures. It may spread to distant organs, such as the lungs and the brain, through the blood or the lymphatic system. Lymph node involvement can also occur. Less common are adenoacanthoma, endometrial stromal sarcoma, lymphosarcoma, mixed mesodermal tumors (including carcinosarcoma), and leiomyosarcoma.
Uterine cancer usually affects postmenopausal women between ages 50 and 60; it's uncommon between ages 30 and 40 and extremely rare before age 30. Most premenopausal women who develop uterine cancer have a history of anovulatory menstrual cycles or other hormonal imbalance. About 37,000 new cases of uterine cancer are reported annually, with approximately 6,400 deaths predicted for 1999.

Cervical cancer:
Causes
(Handbook of Diseases)
The human papillomavirus (HPV) is accepted as the cause of virtually all cervical dysplasias and cervical cancers. Certain strains of the HPV (16, 18, 31) are associated with an increased risk of cervical cancer. Several predisposing factors have been related to the development of cervical cancer: intercourse at a young age (younger than age 16), multiple sexual partners, and herpesvirus 2 and other bacterial or viral venereal infections.

Uterine cancer:
Causes
(Handbook of Diseases)
Uterine cancer seems linked to several predisposing factors:
❑ low fertility index and anovulation
❑ abnormal uterine bleeding
❑ obesity, hypertension, or diabetes
❑ familial tendency
❑ history of atypical endometrial hyperplasia
❑ estrogen therapy (still controversial).
Generally, uterine cancer is an adenocarcinoma that metastasizes late, usually from the endometrium to the cervix, ovaries, fallopian tubes, and other peritoneal structures. It may spread to distant organs, such as the lungs and the brain, through the blood or the lymphatic system. Lymph node involvement can also occur. Less common uterine tumors include adenoacanthoma, endometrial stromal sarcoma, lymphosarcoma, mixed mesodermal tumors (including carcinosar- coma), and leiomyosarcoma.
