Types of Ovarian Tumors: Germ Cell Tumors

00:01 Here, we have our second family of germ cell tumors.

00:05 The first family was surface-derived and serous is something that we?ll take a look at in greater detail.

00:11 Something that I wish to mention here about germ cell tumors.

00:14 You?ve heard of this quite a bit.

00:16 And you?ve heard of this and you?ve focused on this a lot more when you did testicular tumors.

00:23 The family that?s most common of testicular tumors by far is germ cell tumors.

00:28 And specifically, under germ cell tumors in testicular, you looked at a subtype that also began with the letter S.

00:38 But that S in germ cell tumor was seminoma in a male.

00:42 Do you remember? Here, we have germ cell tumor.

00:46 Let?s take a look.

00:49 So if your surface-derived epithelial tumors were approximately 65-70% frequency, a far distant second, germ cell tumor ? look at the frequency, 15-20%.

01:04 Do you need to know it? Sure, for the boards.

01:06 Well, I?ll walk you through the high yield germ cell tumors.

01:09 But when it comes to focusing, you focus upon surface-derived first.

01:13 And you take a look at the serous in greater detail, the mucinous and the endometrioid.

01:19 A proportion of malignant here drops 3 to 5%.

01:22 Remember in surface-derived, it was 90%.

01:25 A whopping 90%.

01:27 The age group here is well quite young with germ cell tumors.

01:30 And the types, well ? But first, we?ll take a look at the demographics.

01:33 20% of all ovarian tumors, not 85%.

01:37 Women here, well, germ cell tumor, you should be thinking about younger age females.

01:42 She in fact ? Well, you might have heard things like choriocarcinoma.

01:48 You might have heard of yolk sac tumors.

01:52 Okay? Young females.

01:54 The exception will be cystic teratoma, which occurs during the reproductive age and we will be spending quite a bit of time with cystic teratoma.

02:04 The homology to germ cell tumors of the male testis -- yes, homology is important.

02:10 For example, when you talk about germ cell tumor in a female known as a dysgerminoma.

02:16 Its equivalent in a male is the most common testicular tumor in a male and that being your? Good.

02:24 Seminoma.

02:25 So those kinds of things I will point out to you to make sure that we?re doing both men and women pathology in tumors in parallel.
