Overview
On microscopic histopathological analysis of testicular cancer, fried-egg appearance is the characteristic finding of seminoma; marked nuclear atypia is the characteristic finding of embryonal carcinoma; blander cytomorphology, hyaline-type globules, and Schiller-Duval bodies are characteristic findings of yolk sac tumor ; syncytiotrophoblasts and cytotrophoblast cells are the characteristic findings of choriocarcinoma.
Pathophysiology
- More than 90% of all testicular cancers are germ cell tumors. This type of cancer starts in germ cells, which are the cells that make sperm.[1]
- About 50% of all germ cell tumours are seminomas, or seminomatous germ cell tumours. They grow slower than non-seminomas.
Microscopic Pathology
Germ cell Tumors[2]
- Clonal proliferation of neoplastic germ cells
- Fried-egg appearance
- Non-seminomas
-
- Marked nuclear atypia
-
- Blander cytomorphology
- Hyaline-type globules
- Schiller-Duval bodies
-
- Both syncytiotrophoblasts and cytotrophoblast cells
