Highly transient population, multiple sexual partners and high prevalence of unprotected sex behaviors suggest a potential rapid spread of sexually transmitted diseases (STD) in China. However, there are some 200 non-sexually transmitted diseases involving the genitalia, etiologically falling into 23 types. To avoid unnecessary medical disputes, enough attention should be paid to the differential diagnosis of non-sexually transmitted diseases in the genitalia.

Filipinos have often been classified as a race having low risk for developing prostate cancer (CaP), and likewise a low risk of dying from the disease. This has mostly been based on information indicating similar patterns among men of Asian decent. But with the changing trends in the disease, both worldwide and in the Asian region, should Filipinos continue to be regarded as such? To attempt to answer this question, a literature search was performed using the following online databases: Medline, SUMsearch, CancerLit, and National Library of Medicine Gateway. The search terms used were "prostate cancer," "Filipino," "Asians," "incidence," and "prognosis." A total of 39 publications were included in this review. In all the studies that segregated Asians into its component subpopulations, Filipinos were noted to have the highest incidence rate (IR) among Asians residing locally, and also the highest or second highest IR among Asian immigrants residing abroad. Studies that focused on the Asian region consistently found an increasing trend in IR of CaP for all subpopulations, with the Philippines experiencing one of the fastest rising IR. Filipinos, both residing abroad and locally, were also observed to have the highest mortality rate (MR) among all the Asian subpopulations included, with an even higher MR than Caucasians reported by certain studies. Evidence was found in this review suggesting that Filipino men may not have the low risk of developing and dying from CaP, as is popularly believed, and may have similar risk of death from CaP as Caucasians.

Scrotal leiomyomas with atypical bizarre nuclei are rare, which might be misdiagnosed as malignant tumor. We describe a case of scrotal bizarre leiomyoma in a 65-yr-old man. The tumor was a 1 cm-sized, well circumscribed, oval mass arising from the tunica dartos muscle. Histologically, it was formed by whorling bundles of fusiform cells with occasional atypical, pleomorphic nuclei and pseudoinclusions. Mitosis was not found. Although morphologically atypical, scrotal bizarre leiomyomas take on a biologic behavior not different from that of conventional leiomyoma, they should be distinguished from leiomyosarcoma to avoid unnecessary treatment.

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.

OBJECTIVETo investigate the clinical manifestations, pathological features, diagnosis and treatment of stromal tumor in the seminal vesicle.

METHODSWe retrospectively analyzed 1 case of stromal tumor of the seminal vesicle, reviewed relevant domestic and international literature, and summarized the clinical manifestations, pathological features, diagnosis and treatment of the tumor.

RESULTSThe patient was a 50 years old male, who underwent excision of the tumor together with the seminal vesicle. Pathology showed it to be stromal tumor of the seminal vesicle. Ultrasonography and CT found no recurrence 10 months after surgery.

CONCLUSIONStromal tumor of the seminal vesicle is rare and easy to be misdiagnosed. Digital rectal examination, and ultrasonography, CT and MRI of the urinary system are useful for its diagnosis. The currently accepted treatment is surgical removal of the tumor, and the prognosis is good.
