The most common sites for EGGCTs are in midline locations such as the mediastinum, retroperitoneum and pineal gland. These tumors rarely present in the stomach. We describe here a case where a middle aged man presented with typical symptoms of gastric cancer. After extensive workup, which included blood work, CT abdomen scan, upper endoscopy, and endoscopic ultrasound, the patient was diagnosed with gastric cancer. However, due to very high blood levels of alpha-fetoprotein, the specimen was sent for special histochemical staining, which demonstrated that the tumor had features of both adenocarcinoma and endodermal sinus tumor. This is a very aggressive tumor with a very poor prognosis.展开更多

Methods: Three cases with primary mediastinal seminoma from 1985 were retrospectively studied. They were male, aged 23, 36 and 32 years respectively. The primary symptoms were chest pain and coughing. The chest X-ray examination revealed solid round mass in the anterior mediastinum, with the diameters varied from 3 cm to 18 cm and a smooth clear edge. The diagnosis was not clearly in all three cases, and then operation was performed. Results: There were no operative deaths and complications. The tumor was radically removed in 2 cases and palliatively removed in 1 case. The post-operative pathological diagnosis is seminoma in all three cases. Radiotherapy were performed in 4 weeks after operation. All cases have been followed up to now, with 1 cases of death and 2 cases survival. Conclusion: Primary seminoma of the mediastinum is very rare. Operation is the main treatment for the primary mediastinal seminoma. Seminoma shows a good prognosis.展开更多

For patients about to undergo a surgical procedure or to receive chemical therapy, radiation therapy, loss or impairment of fertility is a major issue. So the need for fertility protection and preservation became more intensity. Sperm banking is a standard accepted procedure for males to circumvent loss or damage to spermatozoa. Here we present a successful pregnancy in a testicular germ cell tumor patient following fertility preservation.展开更多
