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.

Pathogenesis

  • 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
