background: over recent decades a possible decrease in sperm quality and an increase in the incidence of testicular cancer have been reported in many populations. some recent findings, as cohort studies, showed an increased risk of testicular cancer in men with abnormal semen analysis. case: a 30 years old man referred to our clinic with chief compliant of infertility for 3 years. spermogram re...

Malignant extragonadal germ cell tumors can arise anywhere along the gonadal ridge. Locations may include the retroperitoneal, mediastinum, presacral region, and pineal gland [1]. An Extragonadal Germ Cell Tumor (EGCT) is by definition a germ cell neoplasm displaying one of the histologies associated with gonadal origin, but located outside of the gonads [2]. EGCT arise from primordial germ cel...

Testicular tumors are relatively rare and comprise 1% of all male cancers worldwide with peak prevalence in the age group 15-35 years. lesions have a varied histomorphological spectrum largely categorized as non-neoplastic neoplastic lesions. To study incidence testicular lesions, to including well determine age-wise distribution, laterality clinical presentation The present is an observational...

Testicular germ cell tumors (TGCTs) are the most frequent solid malignant tumors in men 20-40 years of age and the most frequent cause of death from solid tumors in this age group. TGCTs comprise two major histologic groups: seminomas and non-seminomas germ cell tumors (NSGCTs). NSGCTs can be further divided into embryonal carcinoma, Teratoma, yolk sac tumor, and choriocarcinoma. Seminomas and ...

objective: the aim of the present study was to estimate crude and age-standardized incidence rates for oral and pharyngeal nonsquamous cell malignant tumors in kerman province over a period of 11 years. materials and methods: the data used in this retrospective population-based study were extracted from the records registered in all pathology centers of kerman province from 1991 to 2001. all co...

PURPOSE We reviewed cases of intrascrotal tumors treated at our institution except for germ cell testicular tumors. PATIENTS AND METHODS From 1977 to 1998 (22 years), 120 cases of intrascrotal tumors treated at the University of Tsukuba. Of these, 15 cases (12.5%) were not germ cell testicular tumors. The patients' ages varied between 2 and 77 years with a mean of 49.6. RESULTS The most com...

BACKGROUND Our aim was to analyze treatment results and survival characteristics of our patients with malignant sacrococcygeal germ cell tumors. PROCEDURE Patient files of children with malignant sacrococcygeal germ cell tumors, treated at our institution between 1979 and 2009, were searched. Patient characteristics, histopathological subtypes, extension of disease, alpha-fetoprotein (AFP) le...

testicular germ cell tumor (tgct) is the most solid tumor in 20-40 years old man. tgct account for 95% of testicular tumors and represent a unique type of human cancer from several different perspectives. tgct arise by transformation of germ cells. the transformed germ cells exhibit ploripotentially to differentiate into embryonic. extra-embryonic, and somatic tissue types, and are highly sensi...
