Seminal Vesicle Cystadenoma Presenting as a Giant Cystic Abdominal Mass: Case Report and Literature Review

Benign primary tumors including cystadenomas are the rarest tumors of the seminal vesicles. All around only 22 cases of cystadenoma of the SV have been reported since 1944. The diagnosis is typically made on final pathology since clinical findings and imaging techniques are non-specific. The only curative treatment is surgical resection, either by open or laparoscopic surgery. In our work, we report the case of a giant seminal vesicle cystadenoma in an 80 yearsold patient in whom the huge abdominal cystic mass was suspicious to be related to a malignant process since it presented intimate contact with pelvic structures. Pathological examination after excision of the mass has confirmed the nature of the huge mass as a benign cystadenoma of the seminal vesicle
