Benign and Malignant Conditions of the Uterus, Cervix, Fallopian Tubes, and Ovaries (Moulton) Flashcards
Upper vagina, cervix, uterus & fallopian tubes are formed from the?
Paramesonephric (Mullerian) ducts
The absence of a __1__ and absence of the Mullerian inhibiting substance leads to the development of the paramesonephric system with the regression of the mesonephric system.
Paramesonephric ducts arise at __2__ weeks gestational and by __3__ weeks they fuse in the midline to form the __4__.
1) Y chromosome
2) Six
3) Nine
4) Uterovaginal primordium
Uterus didelphysis, Bicornuate uterus w/ a rudimentary horn, or Bicornuate uterus with or without double cervices are all due to failure of?
Paramesonephric duct to fuse
Two separate uterine bodies with its own cervix, attached fallopian tube, and vagina is characteristic of?
Uterus didelphysis
Incomplete dissolution of the midline fusion of the paramesonephric ducts leads to?
Septate uterus
Failure of formation of Mullerian ducts can be lead to a?
Unicornate uterus
Meyer-Rokitansky-Kuster-Hauser syndrome is due to the complete lack of development of?
This leads to the absence of?
1) Paramesonephric system
2) Uterus and most of the vagina
The most common congenital cervical anomalies such as Didelphys cervix and Septate cervix are the result of?
Malfusion of the paramesonephric ducts with varying degrees of separation
Early maternal exposure to what drug causes a small T-shaped endometrial cavity leading to cervical collar deformity?
Diethylstilbestrol (DES)
What are the most common neoplasm of the uterus and are characterized by benign tumors derived from localized proliferation of smooth muscle cells of the myometrium?
Uterine leiomyomas (Fibroids)
While they are usually asymptomatic, symptomatic fibroids can cause?
1) Heavy uterine bleeding
2) Pelvic pressure/pain
3) Infertility
Symptomatic fibroids are the most common indication for?
Hysterectomy
What race has a 2-3 fold increase risk of leiomyomas?
In terms of childbearing, what increases risk?
1) African American
2) Nulliparity
Fibroids rarely form before __1__ or enlarge after __2__.
They enlarge most frequently during __3__?
This is due to __4__ playing a huge role in its development by stimulating the proliferation of smooth muscle cells.
1) Menarche
2) Menopause
3) Pregnancy
4) Estrogen
What are characterized as spherical, well circumscribed, white firm lesions with a whorled appearance on cut sections?
Leiomyomas (fibroids)
Fibroids arise within the __1__.
This is why __2__ fibroids are the most common.
1) Myometrium
2) Intramural
Which type of fibroid has the highest incidence of infertility?
Submucosal fibroids
The most common presenting symptom of leiomyoma is?
Heavy bleeding
If a palpated mass moves with the cervix is it highly suggestive of a carcinoma?
No, it is highly suggestive of fibroid
What is usually the first therapeutic option for leiomyomas?
Estrogen + Progesterone combination OCPs
A hysteroscopic myomectomy can be performed to remove which type of fibroids?
Submucosal fibroids
What is the definitive surgical therapy for fibroids?
Hysterectomy
What procedure leads to necrosis of the fibroid due to microspheres/polyvinyl alcohol particles occluding the artery feeding the fibroid?
Uterine artery embolization
What soft friable polyps can cause menorrhagia, spontaneous, or post menopausal bleeding?
Endometrial polyps
While saline hysterosonography & hysteroscopy allows for better detection of endometrial polyps, ultrasound may reveal focal thickening of the ____?
Endometrial stripe
While most endometrial polyps are benign hyperplastic masses, they need to be removed with hysteroscopy since ____ may also present as polyps.
Endometrial hyperplasia and carcinoma
What cervical cyst appear opaque with a yellowish or bluish hue?
Nabothian cyst
Nabothian cyst result from __1__ metaplasia in which a layer of superficial __1__ epithelial cells entrap a layer of __2__ cells beneath its surface.
1) Squamous
2) Columnar
What are the most common benign growths on the cervix?
Ectocervical and endocervical polyps
Which cervical polyp are more common and are beefy red in color?
Which are pale in appearance?
1) Endocervical polyps
2) Ectocervical polyps
