Seminoma

Seminoma
  • Testicular seminoma originates in the germinal epithelium ( epithelial layer of the seminiferous tubules of
  • 50% of germ cell tumors of the testicles are seminomas.

62-year-old male presents with a history of hypogonadism

US in the transverse plane through both testes shows decrease echogenicity and diffuse heterogeneity of the smaller right testis, with foci of microlithiasis.

Pathology revealed a stage 1 seminoma.

28-year-old male presents with a right testicular pain.

US in the transverse and sagittal planes through the right testicle shows multicentric hypoechoic nodules some of which are hyper vascular.  One of neoplastic nodules appears to extend into the region of the head of the epididymis and insertion of the cord.

US in the sagittal plane through the normal sized right testicle shows multicentric hypoechoic nodules most likely reflecting malignant disease

US in the transverse plane through the right testicle shows a hypoechoic nodule some of which appears to extend into the region of the head of the epididymis and insertion of the cord near the hilum.

Doppler US in the transverse and sagittal planes through the right testicle shows multicentric hypoechoic nodules some of which are hyper vascular. One of neoplastic nodules appears to extend into the region of the head of the epididymis and insertion of the cord.

Pathology:

Germ cell tumor with findings classical of seminoma.  There was involvement of the rete testis, and hilar stromal tissue.  The tumor penetrated the tunica albuginea. Multifocal angiolymphatic invasion TNM pT2 Nx Mx

35-year-old male presents with a right testicular pain.
US in the sagittal plane through the right testicle shows multicentric hypoechoic nodules involving the entire testis. The neoplastic nodules appear to be confined to the testis
