A rare case of primary testicular germ cell tumor spontaneously remitted after metastasis. Testicular ultrasound is crucial for diagnosing retroperitoneal germ cell tumors in patients with normal testes.

Area of Science:

  • Oncology
  • Urology
  • Radiology

Background:

  • Primary germ cell testicular tumors can metastasize.
  • Spontaneous remission of metastatic disease is rare.

Observation:

  • A 21-year-old male presented with a retroperitoneal mass.
  • Testicular examination was normal.
  • Testicular ultrasound revealed a hyperechoic area with acoustic shadowing, suggestive of a tumoral scar.

Findings:

  • Histological analysis post-orchidectomy confirmed a mixed non-seminomatous germ cell tumor.
  • The findings suggest spontaneous regression of the primary testicular tumor after metastasis.

Implications:

  • Testicular ultrasound is recommended for patients with retroperitoneal germ cell tumors and normal palpation findings.
