Patients with prostate cancer involving the SVs were excluded. Cystic lesions were sampled by fine\u2010needle aspiration and solid lesions by core biopsy, all under sonographic guidance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 450 patients who underwent TRUS between January 1997 and December 2001, 10 (2%) were found to have SV masses; 5 masses were cystic and 5 were solid. Cytologic evaluation of aspirated specimens revealed benign findings in all 5 cysts. Four of the 5 patients with solid SV masses had chronic schistosomiasis, and the mass in the fifth patient was a metastatic deposit from a renal cell carcinoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>SV masses may be responsible for lower urinary tract symptoms in a small fraction of cases. A cystic mass is presumptively benign, whereas a solid lesion has a small probability of being malignant, especially if the patient has a primary neoplasm elsewhere. Schistosomiasis should always be considered when making a differential diagnosis in patients who live in areas where infestation is endemic. \u00a9 2003 Wiley Periodicals, Inc.
