A

yolk sac tumor or choriocarcinoma

21
Q

If embryonal carcinoma undergoes furtherembryonic embryonic differentiation, it is a ____

A

teratoma

22
Q

intratubular germ cell neoplasia (ITGCNU)

A

cancer cells are confined to tubules –> seen adjacent to all germ cell tumors in adults except spermatocytic seminoma

23
Q

most common pure germ cell tumor composed of relatively uniform cells with abundant clear cytoplasm ,well defined cell borders, and nuclei with one or more prominent nucleoli.

A

seminomaq

24
Q

_____ are like seminomas but occur in extragonadal sites

A

germinomas or dysgerminomas in females

25
Q

T/F most seminomas are painless

A

T

26
Q

In seminoma which serum markers are negative?

A

HCG and AFP

27
Q

Seminomas are associated with infiltration by what kind of cell?

A

lymphocte

28
Q

Germ cell tumor composed of cells with epithelial appearance and marked cytologic atypia.

A

embryonal carcinoma

29
Q

Prognosis of embryonal carcinoma

A

poorest of GCT –> very aggressive with metastasis

30
Q

Cure rate of seminoma

A

stage 1 and 2 > 95%

31
Q

Cure rate of embryonal carcinoma

A

stage 1 > 95

32
Q

GCT characterized by a variety of growth patterns that recapitulate yolk sac, allantois and extraembryonic mesenchyme

A

yolk sac tumor

33
Q

T/F embyronal carcinoma does not occur in children

A

T

34
Q

T/F yolk sac tumors do not occur in children

A

F –> 75% of childhood testicular tumors are YST

35
Q

Lacelike or reticular growth pattern

A

YST

36
Q

Schiller Duval bodies

A

structures resembling endodermal sinus = yst

37
Q

High serum AFP is associated with what kind of tumor?

A

YST

38
Q

Prognosis of YST children vs adults

A

children do better

39
Q

GCT composed of mononucleated cytotrophoblast and multinucleated syncytiotrophoblast

A

choriocarcinoma

40
Q

Hemorrhage is a hallmark of what GCT?

A

choriocarcinoma

41
Q

High HCG is associated with what GCT

A

choriocarcinoma –> higher hcg = worse prognosis (worst of all GCTs)

42
Q

Tumors with more than one somatic tissue of different germinal layers

A

teratoma

43
Q

Mature teratoma

A

can recognize matured aspects like teeth or glands (vs. immature when there is lots of undifferentiated cells)

44
Q

Most common neoplastic transformation of immature teratoma
