ICD-O-3 Morphology Codes
If the diagnostic term in the pathology report is not in the list below,
be sure to consult your ICD-O-3 manual.
60% of testicular cancers will show a single cell type; the remainder will
show mixed cell types.
| Germ cell tumors (germinoma, 90643; germ cell tumor,
nonseminomatous, 90653) |
| |
Seminoma (90613, 90623, 90663; most common 40-50%;
slow to spread; more likely to occur in older patients; highly radiosensitive;
good prognosis)
|
| |
Non-Seminoma (teratoma and embryonal carcinoma comprise
50% of all testicular cancers) |
| |
|
Teratoma (90803, 90823, 90833) |
| |
|
Malignant trophoblastic teratoma (91023) |
| |
|
Embryonal carcinoma (90703; also called embryonal cell carcinoma--poorer
prognosis)
Teratocarcinoma (90813; a combination of teratoma and embryonal carcinoma;
may metastasize as embryonal or teratocarcinoma) |
| |
|
Yolk sac tumor (90713; also called endodermal sinus tumor, infantile
embryonal carcinoma; common under the age of 15) |
| |
|
Choriocarcinoma (91003; rare < 0.5%; aggressive; metastasize only
as choriocarcinomas) |
| |
|
Choriocarcinoma with other germ cell elements (91013) |
| |
Note: seminoma mixed with non-seminoma should be considered
non-seminoma for treatment decisions. |
| |
Others--less than 5% of testicular cancers (not included
in testicular staging) |
| |
Non-germinal tumors--arise from testicular mesodermal
tissue; rare as malignancies |
| |
|
Leydig cell tumor (86503) |
| |
|
Sertoli cell tumor (86403) |
| |
Lymphoma--most common in men over 60 years old |
| |
Rhabdomyosarcoma (rare) |
| |
Melanoma |
