Gyn and Breast Flashcards
Diseases of the vulva and vagina are most often
inflammatory, rendering them more uncomfortable than serious. Malignant neoplasia is uncommon.
Vulvitis, inflammation of the vulva, can be caused by
infection, contact irritant, allergic reaction, or traumatic injury.
Vulvitis
A variety of pathogens has been associated and often
sexually transmitted.
Vulvitis
In addition, the moist environment supports
fungal infections (Candida albicans).
Vulvitis
Contact irritation or allergic reaction may be related to a number of
agents, including soaps, perfumes, deodorants, clothing textiles, etc.
Vulvitis
Scratching-induced trauma secondary to
associated pruritus (itching) may exacerbate the primary condition.
Vaginitis, inflammation of the vagina, is relatively common and results in production of
vaginal discharge (leukorrhea).
Vaginitis
A variety of organisms have been associated, including
bacteria, fungi, and parasites.
Vaginitis
Many associated orgs are normal commensal organisms that become
pathogenic under certain circumstances, such diabetes, systemic antibiotic therapy (which disrupts normal microbial flora), or immunodeficiency.
Vaginitis
Candida albicans and Trichomonas vaginalis are
frequent offenders.
The cervix must act as a
barrier to prevent entrance of air and microflora into the uterus but at the same time permit escape of menstrual flow and be capable of dilation to accommodate childbirth. This location represents the site of one of the most common cancers in women.
Cervicitis is inflammation of the
cervix, is extremely common and is associated with purulent vaginal discharge.
Cervicitis
The process may be secondary to
specific infections such as candida, trichomonas, chlamydia, gonorrhea, syphilis, HPV, or herpes; but more commonly, it arises from nonspecific infections and is seen in virtually every multiparous woman.
Cervicitis
It may be
acute or chronic.
Cervicitis
In severe lesions, it is difficult to
clinically distinguish from carcinoma and biopsy is required for diagnosis.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
At one time, this cancer was the
leading cause of cancer deaths in women; but currently, it ranks 14th (12,820 cases and 4,200 deaths predicted in the US in 2017).
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
In contrast, the discovery of preinvasive intraepithelial cervical neoplasia has
increased significantly.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
The Papanicolaou cytologic test (Pap smear, 1940) is responsible for the
increased discovery of these earlier lesions, most of which are cured by effective therapy.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Exfoliated cells collected from the cervix are processed with a
special stain (Papanicolaou stain). This allows identification of precancerous (dysplastic) cytological features. This test is inexpensive, however, false positives/negatives are recognized and additional HPV testing is now standard with abnormal Pap tests.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Several factors tend to increase the prevalence; the four most important are
early onset of coitus, multiple sexual partners, a male partner with multiple previous sexual partners, and persistent infection with “high-risk” HPV (16, 18).
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
HPV is present in
85-90% of cervical neoplasia.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
In spite of this correlation, research has shown that
something more than viral action must be involved in the evolution of invasive cervical carcinoma.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Approximately 75-95% of cervical cancers present as
squamous cell carcinoma.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Most (perhaps all) invasive cervical carcinomas arise from
precursor lesions termed cervical intraepithelial neoplasia (CIN).
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Not all CIN progress to
cancer.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
The cancer is now known to be the end stage of a continuum of
progressively more dysplastic changes in which one slowly progresses on to the next stage; this progression evolves slowly over the course of many years.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Cervical intraepithelial neoplasia is
graded I (Mild) – III (Carcinoma in situ); the higher the grade, the greater the likelihood of progression to carcinoma.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Although probable in many instances, progression to
carcinoma is not inevitable, even in higher-grade lesions.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Screening for cervical neoplasia via cytology (Pap smear) and cervical examination (colposcopy) remaining the
standard approach.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Abnormalities revealed during a
colposcopy examination following application of acetic acid appear as white patches.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Upon discovery of a high-grade lesion,
biopsy always is necessary to confirm the cytologic findings and to evaluate for invasion.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
CIN typically is
asymptomatic.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Once invasive, the main symptoms of the carcinoma are
irregular vaginal bleeding, leukorrhea, painful coitus and dysuria.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Treatment of cervical carcinoma is
surgery and/or radiation and chemotherapy; in situ lesions have a 100% survival rate, while the prognosis of invasive lesions correlates directly with the stage.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Deeply invasive stage 4 carcinomas have only a
10% survival.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Recent reports indicate that chemotherapy may
improve survival in advanced cases.
Cervical Intraepithelial Neoplasia and Carcinoma of the Cervix
Introduction of HPV vaccines (now available: Gardasil-9: 6, 11, 16, 18, 31, 33, 45, 52, 58) have been shown effective in decreasing the frequency of genital warts, condylomas (low-risk HPV types 6, 11) and CIN and are expected to decrease cancers associated with these
HPV serotypes, possibly including oropharyngeal/tonsillar cancers in both men and women.
• Uterine corpus is responsible for majority of female
reproductive tract diseases
Uterine • Disorders often
chronic and recurrent
Structure of Uterus
• Myometrium o Muscular wall of the uterus o Composed of interlacing bundles of smooth muscle • Endometrium o Glandular lining of the uterus o Changes under hormonal influence

By far, the most common complaints related to disorders of the uterus are
pelvic pain and abnormalities in menstrual function: menorrhagia (profuse or prolonged bleeding), metrorrhagia (irregular bleeding between periods), and dysmenorrhea (unusually painful menstrual bleeding).
Uterine disorders;
Common causes include, but are not restricted to
endometriosis, endometrial hyperplasia, leiomyomas, and endometrial carcinoma.
Endometriosis is the presence of endometrial glands and/or stroma in locations
other than the uterine lining (10% women in reproductive years, 50% of women with infertility).
Endometriosis
The most common site is in the
pelvis (ovaries, uterine ligaments, tubes and rectovaginal septum).
Endometriosis
Less common sites include the
peritoneal cavity, umbilicus, lymph nodes, lungs and even heart or bone.
Endometriosis
Although the causation is unknown, the most accepted
“regurgitation” theory proposes that menstrual endometrium backflows through the fallopian tubes and also somehow enters the local venous and lymphatic systems.
Endometriosis
Sites of endometriosis are
functional and undergo cyclic bleeding.
Endometriosis
With long-standing disease,
seepage and organization of the blood leads to widespread fibrosis and adherence of pelvic structures; severe dysmenorrhea (painful menstruation), dyspareunia (painful intercourse), dysuria, pain upon defecation, and pelvic pain may occur secondary to intrapelvic bleeding and periuterine adhesions.
Endometriosis
Large blood-filled cysts on the ovaries transform to
“chocolate” cysts as the blood ages.
Endometriosis;
Involvement of the oviducts and ovaries may result in
sterility.
