“…Therefore, accurate exami nation of this organ is important in the evaluation of the infertile male patient. Furthermore, the seminal vesicles may contain tumors [2,3], cysts [4] and congenital abnor malities [5] that require a precise diagnosis. The prostate can easily be palpated via the rectum, but palpation of normal vesicles is extremely difficult, and digital rectal palpation usually provides only suggestive evidence in patients with abnormalities of the seminal vesicles.…”

Evaluation of Seminal Vesicle Characteristics by Ultrasonography before and after Ejaculation

Twenty males underwent transrectal ultrasonography before and after ejaculation to examine possible alterations that could influence interpretation of seminal vesicle ultrasonography. The preejaculation length of 35 mm was significantly (p < 0.05) decreased to 30 mm after ejaculation. The mean width of the seminal vesicles was 13 mm before and 11 mm after ejaculation. The seminal vesicle volume was significantly diminished after ejaculation (p < 0.05). It therefore seems important to maintain a period of abstinence when evaluating the seminal vesicles by ultrasonography.

“…Diagnosis of primary malignant seminal vesicular tumors, including adenocarcinomas, 5,6 anaplastic carcinomas, 7 choriocarcinomas, 8 angiosarcomas 9 and leiomyosarcomas, 10 requires great care, as secondary neoplastic involvement of the seminal vesicle is not uncommon 11 .

A case of squamous cell carcinoma arising within an acquired seminal vesicular cyst is described. A 61-year-old man was hospitalized because of hemospermia and dysuria. Under the diagnosis of a left seminal vesicular cyst, surgical resection was performed. Pathological examination revealed squamous cell carcinoma within a seminal vesicular cyst, along with squamous metaplastic foci and severe chronic inflammation. Cell proliferation, determined with reference to MIB-1 labeling indices, showed a stepwise increase from normal columnar epithelium, through squamous metaplasia, to squamous cell carcinoma. Sporadic p53 protein accumulation without evident gene mutations was also apparent in both the carcinoma and squamous metaplastic lesions. We therefore concluded that the squamous cell carcinoma might have developed from squamous metaplastic foci associated with chronic inflammatory stimulation, within a seminal vesicular cyst.

“…Although benign tumors of the seminal vesicles do occur more frequently, the mass has increased its size in a short follow-up period, and therefore, malignancy had to be excluded to plan the therapeutic strategy for the patient. Primary malignant tumors are extremely difficult to diagnose, 2 but they may require more radical procedures. Due to the above-mentioned reasons, a TRUS biopsy of the mass was arranged with a pathology report of the specimen revealing no malignancy but being inconclusive of the type of the tumor.…”

Background: Cystadenoma is an extremely rare benign tumor of the seminal vesicle. Diagnosis of these tumors and differential diagnosis from malignant ones may be challenging since most of the time symptoms do not occur. Management of these tumors remains debatable due to the limited data in the literature. We present the first robot-assisted laparoscopic excision of a cystadenoma of the seminal vesicle.Case Presentation: A 48-year-old man presented with diminished ejaculate volume and a 3.5 cm right seminal vesicle mass, which increased its size at 6 cm after the 3-month period. Transrectal ultrasound-guided biopsy revealed no malignancy. Robot-assisted laparoscopic excision of the tumor was performed. Port placement was the same as robot-assisted radical prostatectomy. Operative time and estimated blood loss were 240 minutes and 200 mL, respectively. Patient was discharged on postoperative day 3 without any complications. Final histopathologic examination revealed cystadenoma of the seminal vesicle.Conclusion: Surgical intervention may be considered when a cystadenoma of the seminal vesicle is diagnosed and symptoms or tumor growth occurs. Robot-assisted laparoscopic excision is an alternative in the management of these rare tumors.
