Primary leiomyosarcoma of ureter

C E Roemer, R C Pfister, G Brodsky

    Urology
    |November 1, 1980
    PubMed
    Summary

    This report details the tenth case of primary ureteral leiomyosarcoma, a rare cancer. Diagnostic imaging like percutaneous pyelography proved valuable, but the tumor ultimately led to metastasis and death.

    Area of Science:

    • Urologic oncology
    • Medical imaging
    • Surgical pathology

    Background:

    • Primary leiomyosarcoma of the ureter is an exceptionally rare malignancy.
    • This study presents the tenth documented case globally.
    • A review of prior cases is included for context.

    Observation:

    • This case is the first to be investigated using both percutaneous pyelography and ultrasonography.
    • Percutaneous pyelography provided more detailed information compared to retrograde ureterography.
    • Ultrasonography initially suggested a cystic lesion, which contrasted with the actual solid tumor found during examination.

    Findings:

    • The patient underwent nephroureterectomy, para-aortic lymph node dissection, and radiotherapy.
    • Despite aggressive treatment, distant metastasis occurred.
    • The patient succumbed to the disease fifteen months post-diagnosis.

    Implications:

    • Highlights the diagnostic challenges and rarity of ureteral leiomyosarcoma.
    • Emphasizes the importance of advanced imaging techniques in diagnosing rare urologic tumors.
    • Underscores the poor prognosis associated with advanced primary ureteral leiomyosarcoma.
