摘　　要：BACKGROUND Giant multilocular cystadenoma(GMC)of the prostate gland is a very rare benign tumor.Although the benign nature has been known,complete surgical excision is the major treatment consensus because of its high recurrence rate.We report a rare case of GMC with accompanying lower urinary tract symptoms and repeated urine retention initially thought to be symptoms of benign prostatic hyperplasia,which was treated with robot-assisted laparoscopic radical prostatectomy.CASE SUMMARY A 65-year-old man presented with a 2-year history of lower urinary tract symptoms that had deteriorated gradually within the previous six months,even though he had received treatment with a selective alpha-blocking agent.He had undergone two transurethral resections of the prostate(TURP)at a local hospital during a 4-mo interval because initial ultrasound imaging and prostatic core needle biopsy showed benign prostate hyperplasia.Upon the third recurrence,the patient underwent TURP with a green-light laser at our institution.The diagnosis was a tumor composed of variously sized dilated glandular and cystic structures lined by blended prostatic type epithelia positive for prostate-specific antigen;the final diagnosis was giant multilocular cystadenoma.Magnetic resonance imaging showed a large multilocular retrovesical mass 8.0 cm×7.3 cm×6.4 cm,with heterogeneous enhancement.A coexisting malignant part could not be excluded.Considering the high recurrence rate,risk of coexisting malignancy,and possible sequelae of open surgery for radical excision,the patient decided to undergo robot-assisted radical prostatectomy,with good outcomes at the 2-year follow-up.CONCLUSION Robot-assisted surgery for the treatment of prostate GMC provides another choice for simultaneous attention to disease-control and postoperative quality of life.
