Q

What is an Endometrioid Tumor of the ovary?

A

Ovarian Surface Epithelial Tumor with endometrial histology (looks like endometrial cells)

  1. usually malignant => carcinoma
  2. may be associated with endometriosis

Q

Where do Surface Epithelial Tumors (carcinomas) of the ovary tend to spread?

A

Locally => especially peritoneum (“omental caking”)

23
Q

What is a useful serum marker used to monitor treatment response and screen for recurrence of Surface Epithelial Tumors of the ovary?

A

CA-125

not used for initial screening

24
Q

What is the second most common type of ovarian tumor?

A

Germ Cell Tumor = 15% of all cases

25
What population of women do Germ Cell Tumors generally occur in?
women of reproductive age
26
What are the tumor subtypes of Germ Cell Tumors?
Mimic tissues normally produced by germ cells Fetal => Cystic teratoma / Embryonal Carcinoma Yolk Sac => Yolk Sac Tumor Germ Cells => Dysgerminoma Placenta => Choriocarcinoma
27
What is a Cystic Teratoma composed of?
fetal tissue derived from two or three embryologic layers
28
What is the most common germ cell tumor in females?
Cystic Teratoma
29
How common do Cystic Teratomas arise bilaterally?
10% of the time (more common in board questions)
30
Are cystic teratomas benign or malignant?
Benign
31
What two things need to be excluded in a Cystic Teratoma to ensure that the tumor is benign?
1. Presence of immature tissue, most commonly neural ectoderm (immature teratoma => malignant potential) 2. Cancer in the tissue of the teratoma/Somatic malignancy, most commonly squamous cell carcinoma of the skin
32
What is Struma ovarii?
Cystic teratoma composed primarily of thyroid tissue => may present as hyperthyroidism
33
What is the most common malignant germ cell tumor of the ovary that is composed of large cells with clear cytoplasm and central nuclei (resembles oocyte)?
Dysgerminoma
34
What is the testicular form of Dysgerminomas?
Seminoma
35
What is the prognosis of Dysgerminomas?
Good prognosis => responds to radiotherapy
36
What serum marker may be elevated in the setting of a Dysgerminoma?
LDH
37
What do you call a malignant germ cell tumor of the ovary that mimics the yolk sac?
Endodermal Sinus Tumor
38
What is the most common germ cell tumor in children?
Endodermal Sinus Tumor
39
What serum marker may be elevated in the setting of an Endodermal Sinus Tumor?
AFP
40
What unique histological finding is common in Endodermal Sinus Tumors
Schiller-Duval bodies = glomeruli-like structures
41
What do you call a malignant Germ Cell Tumor composed of trophoblasts and syncytiotrophoblasts (villi are absent)?
Choriocarcinoma = malignant proliferation of placental-like tissue
42
How does a Choriocarcinoma spread? How can it spread early?
Small, hemorrhagic tumor with early hematogenous spread How? => genetically programmed to invade blood vessels from the early beginning
43
What serum marker is present in the setting of Choriocarcinoma?
High beta-hCG
44
Do Choriocarcinomas have a good or bad response to chemotherapy?
Bad! Unforunately, they respond poorly
45
What do you call a malignant Germ Cell Tumor composed of large primitive cells that are embryo-like?
Embryonal Carcinoma
46
Do Embryonal Carcinomas typically metastasize?
Yes, aggressive with early metastasis
47
What various cell types can give rise to Sex-cord Stromal Tumors?
Granulosa cells Theca cells Fibroblasts, fibrous tissue Sertoli cells Leydig cells
48
What do you call a Sex-cord Stromal Tumor composed of neoplastic granulosa and theca cells and which produces estrogen?
Granulosa-Theca Cell Tumor
49
What are the presenting symptoms of Granulosa-Theca Cell Tumors?
Signs of excess estrogen Child => precoccious (early) puberty Pre-menopausal Adult => Heavy/abnormal menstrual bleeding Post-menopausal adult => abnormal uterine bleeding
50
What are the unique features of Sertoli-Leydig Cell Tumors?
Sertoli cells form tubules (mimics testicles) Leydig cells contain characteristic Reinke Crystals
51
Why is a Sertoli-Leydig Cell Tumor associated with hirsutism and virilization?
tumor may produce androgen
52
What do you call a benign tumor of fibroblasts that is associated with pleural effusion and ascites (Meigs syndrome)?
Fibroma
53
What are the two classic examples of Metastasis to the ovaries?
1. Kruckenberg tumor: mucinous carcinoma that spreads to BOTH ovaries, e.g. can arise from gastric carcinoma 2. Pseudomyxoma peritonei: abundant amount of mucin in the peritoneum, primary mucinous carcinoma tumor in appendix
