Summary

This case study details an extremely rare primary testicular leiomyosarcoma in a 76-year-old man. The patient experienced no recurrence 12 months after radical orchiectomy without adjuvant therapy.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Primary testicular tumors are uncommon, with sarcomas being exceptionally rare.
  • Leiomyosarcoma typically arises in smooth muscle tissues, rarely in the testis.

Observation:

  • A 76-year-old male presented with a 6-month history of left scrotal swelling.
  • Radical orchiectomy was performed for the diagnosed intratesticular mass.

Findings:

  • Microscopic examination confirmed primary testicular leiomyosarcoma.
  • This represents the 9th documented case globally.
  • The patient remained recurrence-free at 12 months post-surgery without adjuvant treatment.

Implications:

  • Highlights the rarity of testicular leiomyosarcoma and the importance of accurate pathological diagnosis.
  • Suggests radical orchiectomy may be a sufficient treatment for localized primary testicular leiomyosarcoma.
  • Contributes to the limited understanding of this rare oncological entity.
