Abstract
Giant multilocular prostatic cystadenoma is a rare benign tumor of the prostate gland that presents as a large retroperitoneal pelvic mass. The mass is usually located between the urinary bladder and rectum, and results in obstructive voiding symptoms and a change in bowel habits. Complete surgical excision is the treatment of choice. We present a case of rapid recurrent giant multilocular prostatic cystadenoma after laparoscopic excision for primary case. A previously healthy 54-year-old man presented with acute urinary retention. Prostate MRI showed a large cystic mass approximately 13 cm in size, multiple septa and lobulation in the prostate, and no visible solid lesions. Laparoscopic marsupialization of giant multilocular prostatic cystadenoma cysts was performed. One year later, the patient presented with local recurrence. Repeated laparoscopic complete resection was performed without any complications and further recurrence. Giant multilocular prostatic cystadenoma has the risk of recurrence in case of incomplete resection. Surgical treatment should be performed with the goal of complete removal following the same principles as cancer surgery.
Highlights
Giant multilocular prostatic cystadenoma is a rare benign tumor of the prostate gland that presents as a large retroperitoneal pelvic mass [1,2]
Prostatic cystadenoma is usually characterized by large multilocular cysts that are located between the urinary bladder and the rectum
computed tomography (CT) and Magnetic resonance image (MRI) of giant multilocular prostatic cystadenomas demonstrate the cystic nature of the lesions, which are of various sizes, with multiple septa compressing the bladder and rectum, and without invasive large solid enhancing component [4,10,13]
Summary
1. Introduction Giant multilocular prostatic cystadenoma is a rare benign tumor of the prostate gland that presents as a large retroperitoneal pelvic mass [1,2]. The mass is usually located between the urinary bladder and the rectum, and results in obstructive voiding symptoms and a change in bowel habits [1,3]. Magnetic resonance image (MRI) is used to characterize the giant multilocular prostatic cystadenoma, and findings demonstrate a large retroperitoneal mass with multiple and variable-sized cysts compressing adjacent organs, especially the bladder and rectum [4].
