Sarcoma of the prostate - Sonographic findings and pathologic correlation

Sarcoma of the prostate is a rare malignancy that affects younger men and has a poorer prognosis in comparison with prostate cancer. Transrectal ultrasound (TRUS) and ultrasound-guided biopsy of the prostate are the main methods for early diagnosis. Treatment of prostate sarcoma consists of radical surgery, chemotherapy, and radiotherapy. Absence of metastasis at the time of diagnosis and negative surgical margins are more important for prognosis than tumor size, grade, and histologic subtype.
