00:01
In this section of female
reproductive pathology,
we’ll take a look at the
ovaries in greater detail.
00:09
We’ll begin by looking at benign cyst.
00:11
And as we progress further,
then we’ll take a look at
what may then happen when the
ovaries develop malignancy.
00:20
With benign cyst, a
follicular cyst, multiple.
00:25
Variable size.
00:26
Lined by granulosa and theca cells.
00:28
I want to stop here
for one second.
00:31
Where are you?
You’re in the ovary.
00:34
Inside the ovary of a follicle.
00:36
And there’s every
possibility that these
follicles may then develop
fluid accumulation.
00:41
Isn’t that the definition of a cyst?
And as far as a female is concerned,
she has hundreds of thousands of
these follicles that she’s given.
00:50
And each month of course, one
of these follicles is then
going to rupture the egg and
then out comes the product.
00:57
There’s a follicular cyst,
therefore if it’s a follicle,
the two layers anatomically
will be the outer
layer and that is then
called your granulosa.
01:06
The inner layer of the follicle is called
your theca
if you remember from physio.
01:11
If you’re thinking about
a chocolate cyst,
that was a topic that we had
looked at known as endometriosis.
01:17
And so therefore, there might
be ectopic implantation
of the endometrium on
top of your ovary.
01:24
And every month when
there’s bleeding,
there is a chocolate cyst-like appearance
and I’ve shown you a
picture in endometriosis.

Included Quiz Questions
Which of the following is the CORRECT composition of the lining of follicular cysts in the ovary?
- Granulosa and theca cells
- Endometrium and myometrium
- Giant lymphocytes and smooth muscles
- Stratified columnar epithelium
- Highly vascularized squamous epithelium
Which of the following is the BEST description of the differences between follicular and chocolate cysts?
- Follicular cysts are accumulations of fluid in preexisting ovarian follicles; a chocolate cyst is the result of ectopic implantation of endometrium in the ovary with an accumulation of blood during the menstrual cycle.
- Follicular cysts are caused by viral infections, leading to the development of fluid-filled cavities; chocolate cysts are caused by repeated episodes of PID, leading to an accumulation of necrotic materials in the ovary.
- Chocolate cysts are caused by endometriosis and the resulting accumulation of blood during every menstrual cycle; follicular cysts are remnants of chocolate cysts after all the blood has been cleared by the immune system.
- Chocolate cysts occur after ovarian infection via an amoeba; follicular cysts occur in the preexisting ovarian follicles.
- Follicular cysts are benign, fluid-filled remnants of embryonic ovarian tissue; chocolate cysts occur after the malignant transformation of ectopic endometrium in the ovary.
