A Case of Huge Pulmonary Blastoma With Multiorgan Invasion / 결핵및호흡기질환

A pulmonary blastoma is a rare malignant tumor of the lung that is composed of epithelial and mesenchymal elements and resembles the structure of an embryonic lung. Pulmonary blastomas have a very poor prognosis and make up 0.25 to 0.5 percent of all primary malignant lung tumors. A pulmonary blastoma usually manifests as a solitary parenchymal mass or nodule and multiple subpleural mass with effusion on chest X-ray and computed tomography. We encountered a very rare case of pulmonary blastoma in a 52 years old male. He complained of abdominal pain, fullness, and dyspnea. The radiology examination revealed a huge lung mass invading the mediastinum, heart, diaphragm, and liver. The percutaneous needle biopsies were performed, and this tumor was diagnosed as a pulmonary blastoma. We report a biopsy confirmed case of a huge pulmonary blastoma invading multiple organs.

A Case of Astrocytoma in the Third Ventricle

In children, primary tumors of the third ventricle are uncommon. The majority of the lesion were infiltrating astrocytoma of the anterior portion of the third ventricle. Tumors within the third ventricle were benign, encapsulated, and respectable with good prognosis. But most surgerns have considered this tumors to be inoperable;accordingly shunting procedures followed by radiotherapy has been the treatment of choice. We recently experienced a case of astrocytoma which entirely filled the third ventricle with hemorrhage and reviewed the literatures.

A Case of Teratoid Cyst in the Lumbar Region

One of the least frequently encountered nongliomatous intraspinal neoplasm is the teratoma. Tumors that are not dermoid or epidermoid cyst have been reported as being teratomatous or teratoid when they do not have tissue derived from all three germ layers and when they are clearly most closely related to the trigerminal teratoma. Authors described an illustrated case report of teratoid cyst of the spinal cannal, summarized the previous report cases, and discuss the classification and origin of these tumors.

A Case of Pineal Germinoma with Drop Metastasis to Cauda Equina

Pineal germinoma is one of the most radiosensitive intracranial tumors and so recently a regime of radiotherapy combined with ventricular shunting was advocated. But not infrequently seeding through the subarachnoid space and shunting system was observed. We have experienced a pineal tumor, which was treated completely by irradiation following ventriculo-atrial shunt but without evidence of intracranial recurrence spinal metastasis occurred 16 months later. After myelography total laminectomy from L1 to L3 was performed and intradural tumor was removed. Histopathological diagnosis was germinoma. After would healing spinal axis irradiation was performed with symptomatic improvement.
