Volume 2, Issue 1, January-March, 2012. P a g e | 11 BRIEF HISTORY: A 26-year-old man was referred to the emergency department of our hospital following a car accident. The physical examination was unremarkable except reduced breath sounds over the left hemithorax. Results of blood serum tests were normal. Chest X-ray showed a huge space-occupying mass in almost half of the left hemithorax (Fig...

The lung and stomach are very unusual sites for teratoma. The histologic findings of intrapulmonary and gastric teratomas are not different from those arising in usual sites, such as the ovary or testis. However, preoperative diagnosis is sometimes difficult to make partly because of unusual location. We report here two cases of teratoma, one intrapulmonary teratoma and the other gastric. The i...

Neuroendocrine tumors that arise in an extragonadal teratoma are extremely rare. Somatic-type malignancy, defined as any sarcoma, carcinoma, leukemia, or lymphoma developing in a germ cell tumor, occurs in approximately 2% of all germ cell tumors. Our case represents a mediastinal mass that was incidentally found in a patient with syncope. Surgical resection confirmed mature teratoma with neuro...

BACKGROUND Mediastinal fetal teratoma can be detected as a mass in the chest during a routine prenatal ultra-sound screening. Because of the pressure on mediastinal structures it can be the cause of non-immune hydrops fetalis and polyhydramnion. The development of hydrops fetalis leads to fetal death or premature delivery in most reported cases. Early surgical removal is important, but, the res...

The case is presented of a patient in whom the diagnosis of Klinefelter's syndrome was made only after a mediastinal teratoma was discovered. Chest physicians should be aware of this association since they are often the first to evaluate patients with mediastinal masses.

We report an unusual case of 9.5-cm-sized embryonal rhabdomyosarcoma arose from a mediastinal mature teratoma in a 46-yr-old man. A man presented with chest trauma as a result of an accident at 10 September 2011. On chest X-ray, an anterior mediastinal mass was detected. To obtain further information, chest computed tomography (CT) with contrast enhancement was performed, revealing an anterior ...

We present a 27-year-old female patient admitted with an anterior mediastinal mass. She complained of chest discomfort and hemoptysis which began seven months prior. She had given birth five months prior. Thoracic X-ray showed an anterior mediastinal mass. Thorax computed tomography (CT) confirmed a well-defined anterior mediastinal mass with 13 × 12 cm diameter, extending to the right hemithor...
