Cystadenoma of the Seminal Vesicle: A Case Report of Rare Seminal Vesical Tumor and Review of Literature

Although the secondary involvement of the seminal vesicles by prostate cancer is relatively common, seminal vesicle as a primary site for neoplastic disease is uncommon.1 There are a wide variety of tumors among primary seminal vesicle tumors that are derived from both the epithelium and stroma. Hence, they have been classified as mixed epithelial-stromal tumors. This report describes a 32-year-old man who presented with a retrovesical cystic mass that was initially thought to be a prostatic tumor but demonstrated pathologically to be a cystadenoma of the seminal vesicles.
