Spermatocytic tumor is a rare germ cell not related to neoplasia in situ, and derived from postpubertal-type cells. It was previously called Seminoma due false belief of its origin situ. The usually occurs an older age group orchidectomy curative. We present case spermatocytic 25-year male who presented with right-sided testicular swelling varicocele. Radiology revealed 9.8 × 9 cm mass the pati...

abstract gastrointestinal mesenchymal tumors are a group of tumors originating from the mesenchymal stem cells of the gi tract. digestive tract schwannomas are rare mesenchymal tumors which occur most frequently in the stomach. we report a 56-yearold woman who was examined endoscopically for dyspepsia which she had suffered from since 3 years ago. around gastric antral mass was seen. surgical r...

testicular cancer typically spreads to the lymph nodes, but hematogenous dissemination to distant organs can also occur. bone metastasis is uncommon and is thought to be a poor prognostic indicator. jaw metastasis is exceedingly rare but is of great clinical significance, since it may be the first sign of an occult testicular cancer or the first evidence of relapse of a known tumor. herein, we ...

Tumor neovascularization may occur via both angiogenic and vasculogenic events. In order to investigate the vessel formation during tumor growth, we developed a novel experimental model that takes into account differentiative tumorigenic properties of Embryonic Stem cells (ESCs). Leukemia Inhibitory Factor-deprived murine ESCs were grafted on top chick embryo chorionallantoic membrane (CAM) in ...

INTRODUCTION Development of a sarcomatous component in a germ cell tumor is an uncommon phenomenon. Most cases reported have a grim prognosis. Growing teratoma syndrome is also an uncommon phenomenon and occurs in approximately 2% to 7% of non seminomatous germ cell tumors and should be treated surgically. CASE PRESENTATION We report the case of a 12-year-old Asian girl with an ovarian mixed ...

Ectopic testis predisposes to a high risk of germ cell tumor development. Treatment of advanced testicular germ cell tumor developing in an uncorrected abdominal testis is based on primary chemotherapy followed by removal of the testis along with residual masses. However, persistence of viable tumor particularly in the testis is always noted since testis penetration of chemotherapeutic agents i...
