When surgical treatment for symptomatic seminal vesicle cyst is deemed necessary, conventional surgery is invasive because of the deep location and dissection difficulty of the seminal vesicles in the retrovesical space. Recently, the laparoscopic approach has been advocated as an optimal yet minimally invasive technique for the surgical treatment of seminal vesicle pathology. It provides a good image and easy approach to the seminal vesicles. We report a case of a symptomatic giant cyst of the left seminal vesicle that is associated with ipsilateral renal agenesis, which was treated by transperitoneal laparoscopic excision.

Pelvic organs are generally sufficiently outlined by extraperitoneal fat, and there is a relative absence of physiologic motion. Computed tomography(CF) of the pelvic cavity is advantageous to demarcate anatomical features. It is important to standardize localization and volumetric measurement of intrapelvic organs in each plane of pelvic computed topography image. Forty four cases without pelvic pathology were studied in other to determine the normal morphology of the prostate and seminal vesicles on CT with the standard plane of greater trochanter to be appeared. The shape of pelvic cavity had android type in three-fifths and the size had 60.0~ 153.6mm(mean 95.3+/-17.7 mm) in anteroposterior diameter and 87.6~158.3 mm (mean 102.5+/-13.5 mm) in transverse. About four-fifths of the shape of the prostate had round type on the level of appearing to the largest prostate. About four-fifths of number of appearing plane of prostate on pelvic CT had 3 planes. The mean volume of the prostate was 32.6+/-7.2 ml and the volume of the prostate was well correlated with age(p<0.000). The mean anterior and lateral space of Retzius were 12.0+/-11.8 mm, 16.1+/-14.1 mm respectively. According to patient`s body weight and height, space were not correlated to body weight & height. About a half and one-third of the shape of the seminal vesicles had bow-tie and crescent type on the level of appearing to the largest seminal vesicles. About three-Fifths and one-fifth of number of appearing plane of seminal vesicles on pelvic CT had 2 and 3 planes. The mean length of right and left seminal vesicles was 40.4+/-5.2 mm and 38.7+/-6.1 mm respectively.

OBJECTIVETo investigate the clinicopathological features of primary Burkitt lymphoma of the seminal vesicle.

METHODSWe reported the clinical characteristics, histological changes and the results of immunohistochemical staining and molecular in situ hybridization of 1 case of primary Burkitt lymphoma of the seminal vesicle. We also reviewed the related literature and studied the pathomorphological characteristics and differential diagnosis of the tumor.

RESULTSThe characteristic manifestations of the patient were frequent micturition with dysuria, followed by inguinal lymphadenectasis 2 months later. Medical imaging showed a diffuse and monotonous infiltration of neoplastic cells with scanty cytoplasm and a few mitosis images. Microscopy displayed a starry sky pattern. The tumor cells were positive for CD10, CD20, CD79alpha, Bcl-6 and EBER in situ hybridization, but negative for CD3, CD6 and Cyclin D1. The Ki-67 index was > 95%.

CONCLUSIONPrimary Burkitt lymphoma of the seminal vesicle is a very rare tumor with aggressive behavior. The pathological diagnosis of the tumor depends on histopathological examination and immunohistochemical techniques. However it should be differentiated from diffuse large B-cell lymphoma, lymphoblastic lymphoma and small cell carcinoma of the seminal vesicle or prostate gland.

We reported localized amyloidosis involving seminal vesicles and vasa deferentia, which was found in two patients with prostatic adenocarcinoma. A 60-yr-old (Case 1) and a 59-yr-old (Case 2) man came to our hospital with elevation of serum prostate-specific antigen (PSA) and biopsy proven carcinoma, respectively. MRI revealed multiple irregular foci of low signal intensity in the prostates as well as in both seminal vesicles and vasa deferentia on T2-weighted imaging, suggesting prostatic carcinoma with extension to both seminal vesicles and vasa deferentia in both cases. Under the clinical diagnosis of stage III prostatic adenocarcinoma, a radical prostatectomy was performed in both patients. Microscopically, Gleason score 7 adenocarcinoma was observed in both patients. In addition, isolated amyloidosis of both seminal vesicles and vasa deferentia was found without carcinoma involvement. Localized amyloidosis in the seminal vesicles, which is considered as senile process, has been occasionally reported in the autopsy and in the surgical specimens. Amyloid deposition in the vas deferens has also been reported in the literature, however, the deposition mimicking extension of carcinoma has not been reported. In this report, two cases of isolated amyloidosis of the seminal vesicles and vasa deferentia are described with electron microscopic study and literature review.

BACKGROUND: Pathologic characteristics of the prostatic adenocarcinoma in Korean patients are not clear. We studied 60 cases of radical prostatectomy specimens using mapping analysis in an effort to discover the pathologic characteristics of the Korean prostatic adenocarcinoma. METHODS: A resected prostate was sectioned serially and embedded near-totally. Gleason score, tumor volume or size, capsular extension, involvement of lateral margin, seminal vesicle, vas, apex and base, presence of lymphatic and neural invasion, and presence of high grade prostatic intraepithelial neoplasm (HGPIN) were examined. DNA ploidy and proliferative index were evaluated. RESULTS: Mean values were as follows: age, 63.6 years; serum prostate specific antigen level (sPSA), 24.0 ng/ml; tumor amount (volume, 29.1%; size, 2.4 cm); Gleason score, 7.3; aneuploidy, 23.3%; proliferative index, 14.2%. Involvement rates of apex, base, seminal vesicle, resection margin, nerve and lymphatics were 5.2%, 39.0%, 23.7%, 31.7%, 56.7% and 16.7%, respectively. Rates of multifocal tumors and HGPIN were 43.3% and 63.3%, respectively. The Gleason score was correlated with tumor amount (volume%, p<0.001; size, p<0.01) and tumor extent (T) (p<0.005). Tumor amount was correlated with sPSA (p<0.05) and T (p<0.005). T was correlated with sPSA (p<0.05). CONCLUSION: Korean prostatic adenocarcinomas showed higher Gleason scores, lower HGPIN rates and multifocalities in comparison to western prostatic adenocarcinomas, suggestive of the Korean prostatic adenocarcinomas' late detection.

OBJECTIVETo study the etiopathogenesis and management of seminal vesicle enlargement.

METHODSForty-six cases of seminal vesicle were selected, of which 36 were vesiculitis, treated by antibiotics through a catheter indwelt in the seminal vesicle for 1 week, 3 were cystic vesicular seminalis, given anti-inflammatory treatment by catheter administration and hydatid fluid inhalation, 1 was calculus at the orifice of the ejaculatory duct, taken out by transurethral resection of the verumontanum, 1 was polypous at the orifice of the verumontanum, removed by transurethral resection, 2 were posterior urethritis, treated by fulguration, and 3 were prostatic carcinoma, treated by radical prostatectomy and spermatocystotomy.

RESULTSHemospermia disappeared in 32 cases of vesiculitis during the 6-24 months follow-up, 4 cases experienced recurrent hemospermia 3 months after the treatment. No recurrence was observed in any other case of cystic vesicular seminalis, calculus, polypous, posterior urethritis and prostatic carcinoma.

CONCLUSIONSeminal vesicle enlargement has intricate etiopathogenesis, but can be treated with satisfactory results if managed properly.
