male Path III Flashcards
what testicular tumors are associated with testicular dysgenesis syndrome
the germ cell tumors
seminomatous and non-seminomatous
what is the triad of testicular dysgenesis syndrome
cryptorchidms
hypospadius
poor sperm quality
what are the seminomatous tumors
seminoma
spermatocytic seminoma
what are the non seminomatous germ cell tumors
embryonal Carcinoma
yolk sac tumor
choriocarcinoma
teratoma
why do some patients with testicular torsion develop infertility
because once the blood testicle barrier is broken immune bodies recognize no as self and destory both testicles
when does the carcinoma in situ cell arise in germ cell tumors
with boy at birth
majority germ cell tumors are what
seminomas
embryonal
mixed
germ cell tumor chromatin morphology
i12p band
risk factors germ cell tumors
cryptorchidism, prior GCT
FMH (KIT and BK)
whites>blacks
brothers increase risk if have it
where do germ cells mets to
periaortic abdominal lymph nodes
what serume markers can be + in germ cell tumores
hCG LDH and afetalprotein
how do germ cell tumors present
painless mass
what is the most common GermCellTumor
seminoma
serum markers for seminomas
LDH
hCG
staging of seminomas
low risk-no mets
intermediate risk-mets
what serum marker is never in a pure seminoma
AFP
Tx seminoma
radical orchiectomy +/- retroperitoneal lymph node dissection
Tx low risk seminoma
radiotherapy
Tx intermediate risk seminoma
platinum based chemo
gross morphology seminomas
lobular homogenous fleshy tan cut surface
how do you prevent seeding of seminoma when cutting testis out
through inguinal canal
histo seminoma
large cells with distinct borders, prominent nuclei and watery cytoplasm
lymphoid infiltrate
look like fried eggs
