Prostatic Leiomyosarcoma: Case Report

Introduction:  Sarcoma is a rare tumor, representing less than 0.1% of primary prostate tumors in adults. Of these, leiomyosarcoma is the most common subtype. They are generally found in advanced stages, making the prognosis unfavorable. The approach is variable, with surgery being the preferred management.

Case report:  Male patient, 65-year-old complaining of weak urinary stream and nocturia, presenting, upon rectal exam, a prostatic area of hardened consistency. Imaging tests revealed a large solid prostatic nodule, with transrectal biopsy showing that it was a stromal tumor with uncertain potential malignancy. He underwent radical retropubic prostatectomy, with anatomopathological and immunohistochemical examination confirming prostatic leiomyosarcoma. After surgical and adjuvant treatment, the patient evolved satisfactorily.

Conclusion:  Prostatic leiomyosarcoma is a rare and aggressive tumor. Generally, the prognosis is unfavorable, but it can be improved in patients with localized disease submitted to multimodal treatment.
