Teratomas are tumors composed of tissues derived from more than one germ cell line. Pulmonary teratomas are rare and commonly involve the upper lobe of the left lung. Criteria for pulmonary origin are the exclusion of a gonadal or other extragonadal primary site and origin entirely within the lung. We report a case of a giant pulmonary teratoma in a 2-year-old male child and review the relevant...
Germ cells tumours most frequently occur in the gonads. Extragonadal localisation is rare and concerns mainly the mediastinum, retroperitoneum and pineal. We present the first description of a patient with a mixed germ cells tumour located primarily in the thyroid. A 35-year-old man in a good clinical condition was admitted to diagnose metastasis revealed in an X-ray of his lungs. Abnormal labo...
BACKGROUND Repeated electroacupuncture (EA) stimulation is known to stimulate the activity of the hypothalamus-pituitary-adrenal axis, and to enhance the circulation level of estrogen in the ovariectomized rats. To explore the source of the increased circulation estrogen, the extragonadal aromatization was detected. METHODS Female rats were divided into five groups: 1) intact (INT), 2) intact...
Germ cell tumors are predominantly found in the gonads, and the most common extragonadal site is anterior mediastinum. Usual symptoms are cough, dyspnea, and fever, chest pain due to mass effect or intrapulmonary invasion but hemoptysis is rare and may result from either communication with tracheobronchial tree or may result from bronchial bleeding due to irritation by tumor. As in our case, pa...
A variety of regimens of high-dose chemotherapy with hematopoietic stem cell support for poor risk germ cell tumors have been established. However, a series of chemotherapy steps carried out prior to the harvest sometimes leads to an insufficient number of peripheral blood stem cells. Here, we report a case of a patient who successfully underwent high-dose chemotherapy for the treatment of poor...
