A rare case of cystadenoma of the seminal vesicle in a patient with cancer of the transverse colon

Primary tumors of the seminal vesicles (SVs) are uncommon in the routine practice of urologists. Their diagnosis is complicated by an absence of early signs of the disease. Therefore, usually SVs tumors are detected accidentally during instrumental examinations. Primary tumors of the SVs can be benign. In the Medline, PubMed, and Google Scholar databases we have found 25 descriptions of clinical cases of cystadenomas of the SVs, while in Russian medical literature no publications on the topic can be found. The main diagnostic methods are contrast-enhanced computed tomography, magnetic resonance imaging, and fine needle biopsy. Surgery scale varies from SV resection and vesiculec¬tomy to vesicle resection with prostatectomy and orthotopic neobladder reconstruction and lower anterior resection of the rectum. Considering that primary SV tumors are a rare pathology, there’s no consensus on the scale of surgical intervention.In view of the rarity of the disease and lack of its descriptions in Russian medical literature, we find it interesting to demonstrate a clinical observation of a patient with cystadenoma of the left SV
