CD117 antibodies can also be used in the diagnosis of mast cell tumours and in distinguishing seminomas from embryonal carcinomas.
12.
Microscopy and immunohistochemistry are the only way to give a definitive diagnosis, especially when there is a suspected seminoma.

"I had a seminoma _ a curable cancer _ in my chest, but I'm fine now.
14.
Confusingly, some types of cancer use the "-noma " suffix, examples including melanoma and seminoma.
15.
Seminomas are also much more sensitive to radiation than NSGCTTs, so the noninvasive radiation treatment is often preferred over RPLND.
16.
It is expressed in embryonal carcinoma but not in seminoma and is thus a useful marker in distinguishing between these germ cell tumors.
17.
Microscopic examination shows that seminomas are usually composed of either a sheet-like or lobular pattern of cells with a fibrous stromal network.
18.
Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells.

Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells.
20.
Note that only about 25 % of seminomas have elevated chorionic gonadotropin, so a pregnancy test is not very sensitive for making out testicular cancer.
