    This study details a rare paratesticular leiomyosarcoma case in an elderly man. Electron microscopy confirmed smooth muscle differentiation, highlighting its diagnostic value for rare urological tumors.

    Area of Science:

    • Urological Oncology
    • Surgical Pathology
    • Electron Microscopy

    Background:

    • Paratesticular leiomyosarcomas are rare malignant tumors arising in the spermatic cord or surrounding structures.
    • Diagnosis can be challenging due to their rarity and varied presentations.

    Observation:

    • A case of paratesticular leiomyosarcoma in an 84-year-old male is presented.
    • The tumor was a firm, nodular mass attached to the upper pole of the left testis.
    • Light microscopy revealed a high-grade sarcoma with numerous mitotic figures.

    Findings:

    • Electron microscopy demonstrated tumor cells with features of smooth muscle differentiation, including 7 nm microfilaments and dense bodies.
    • Prominent pools of glycogen were also observed within the tumor cells.

  • These ultrastructural findings were crucial for definitive diagnosis.

    • Implications:

    • This case underscores the importance of electron microscopy in diagnosing unusual urological neoplasms.
    • Accurate diagnosis is essential for appropriate treatment and patient management of paratesticular sarcomas.
    • Further research into the specific ultrastructural characteristics of paratesticular leiomyosarcomas may improve diagnostic accuracy.
