Q

What does this sample from a D&C show?

A

Slide of endometrial tissue in the early secretory phase. No pathology, I think it’s just important to remember “Piano Keys” with this endometrial phase.

Q

Main cause of an anovulatory cycle.

A

Excessive and prolonged estrogen stimulation with unopposed progesterone.
The endometrial stroma starts to break down

Q

How does an inadequate luteal phase cause abnormal uterine bleeding?

A

Inadequate corpus luteum secretes low levels of progesterone. The result is early uterine contraciton and menses.

Q

Name for endometriosis when the ectopic tissue is found beneathe the surface in an ovary.

A

Endometrioma or “chocolate cyst”

-the tissue bleeds and becomes dark in color and viscous so it is called “chocolate”

Q

A woman presents with irregular uterine bleeding that doesn’t seem to respond to any hormonal medication. Ultrasound shows no cystic growths or nodules and D&C reveals no abnormal cells and no endometrial hyperplasia. A hysterectomy is performed and reveals this picture. What’s the diagnosis?

A

Dx: the woman had a picture of a uterus with adenomyosis in her own uterus that caused irritation and abnormal bleeding.

Adenomyosis is the presence of endometrial tissue in the myometrium which causes irregular bleeding. It is only diagnosed upon pathological examination after a hysterectomy.

Q

What are endometrial polyps and the two types?

A

Exophytic masses (tissue of subepithelium that grows out beyond the epithelium) in the uterus that project into the uterine cavity.

  1. Hyperplastic polyps: seen in general endometrial hyperplasia
  2. Atrophic Polyps: seen in postmenopausal women

Q

What is the morphology of endometrial hyperplasia?

A

Increased proliferation of the parenchyma (glands) relative to the stroma (supportive tissue)

Associated with increased estrogen stimulation and either decreased progesterone levels or endometrial insensitivity to progesterone.

Q

A woman presents with irregular uterine bleeding, bloating, and infertility. Ultrasound shows no masses but a slightly enlarged uterus. D&C reveals:

Q

A woman presents with irregular uterine bleeding, bloating, and infertility. Ultrasound reveals no masses but the uterus appears slightly enlarged. D&C reveals:

A

Simple Endometrial Hyperplasia without atypia.

There is proliferation of the cells (back to back appearance) but there is NO crowding of the glands.

Q

A woman presents with irregular uterine bleeding, bloating, and infertility. Ultrasound reveals no masses but a slightly enlarged uterus. D&C reveals:

A

Complex Endometrial Hyperplasia with atypia.

The nuclei have lost their polarity (become fragmented and are not centrally located in the cell) and the nucleoi are prominent.

Q

Describe the 2 types of endometrial carcinoma.

A

Type 1: most common, arises in settings of unopposed estrogen, obesity, diabetes, HTN, and infertility. Spread of endometrial tumor into myometrium and lymph node invasion, that will spread into the lungs, liver, or brain.

Type 2: arises in settings of endometrial atrophy, papillary growth with marked atypia

Q

What are Malignant Mixed Mullerian Tumors (Craniosarcomas)?

A

Adenocarcinomas with stromal differentiation into muscle, cartilage, or osteiod. Tumors arise from Mullerian embryologic derived tissue.

Q

What is a Uterine Leiomyoma and what is its morphology?

A

Fibroids: smooth muscle tumors usually in the uterine myometrium. Have a characteristic whorled pattern of smooth muscle fibers

18
Q

Describe leiomyosarcomas.

A

De novo forming tumors that have two growth patterns: bulky fleshy pattern, and polypoid mass pattern. Notable atypia and increased mitotic index compared to leiomyomas.

19
Q

2 most common fallopian tube infections.

A
  1. Gonococcal (most common)
  2. Chlamydia (more destructive and more commonly progresses to PID)
20
Q

Main complication of Tuberculous Salpingitis.

A

Infertility

21
Q

Name this growth that is filled with clear serous fluid. The patient had no complaints and no irregular bleeding.

A

Benign paratubal cyst. They are often found incidently on Ultrasound or after hysterectomy.

22
Q

What is Stein Leventhal Sydrome?

A

Polycystic Ovarian Syndrome (POCS) or Disease

-numerous cystic follicles associated with oligomenorrhea, persistent anovulation, obesity, hirsutism, virilism

23
Q

Condition often linked with PCOS.

A

Endometrial Hyperplasia: The cysts in the ovaries release high levels of estrogen causing endometrial thickening.

24
Q

What is ovarian stromal hyperthecosis?

A

Hyperplasia of the cortical stroma of the ovary. Usually bilateral and the patients present very similar to PCOS.

25
Q

Name the 3 types of ovarian Surface Epithelial Tumors and the 3 classifications of these 3 types.

A
  1. Serous
