Thymoma is a common anterior mediastinal mass, although thymomas have occasionally been found in the neck, pulmonary hillus, or posterior mediastinum. But a thymoma within the middle mediastinum has rarely been reported. We report a thymoma arising in the middle mediastinum with a review of the literature.

Malignant transformation of teratoma in the anterior mediastinum is rare; the mass usually has a long history and is seen in older patients. We report a case of teratoma with malignant transformation in the anterior mediastinum, complicated by rupture. CT revealed a lobulated, inhomogeneous cystic mass with a fat component and wall calcifications. The lateral wall was disrupted and consolidation in the adjacent left upper lobe was noted, suggesting rupture. A heterogeneously enhanced solid portion, obliterating the fat plane between the mass and the great vessels was present in the medial aspect of the mass, and pathologic examination demonstrated the presence of adenocarcinoma.

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.

A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.

A retrospective analysis was performed on 36 patients with primary cysts and tumors of the mediastinum seen at the Department of Thoracic and Cardiovascular Surgery of Maryknoll Hospital from January 1983 to December 1993. There were 21 female and 15 male patients in the study. Ages ranges from 2 years to 72 years, with a mean of 34.7. There were 9 malignant tumors and 27 benign tumors.Thymic neoplasms were the most common. For the whole series, 29 of the patients had tumors in the anterior mediastinum. There appears to be an in6rease in tumors in the anterior compartment. There were 30 symptomatic patients in our series. Of the patients with malignant disease, 89 % were symptomatic. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation. There were 9[27.3 %] postoperative complications. There was no postoperative mortality. Follow-up was available on 27 patients. There was no recurrence, malignant degeneration, or growth of any tumor. It is hoped that careful evaluation and aggressive treatment of mediastinal tumors will continue to provide improvement in the prognosis for these patients.

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.

Angiolipoma is a rare benign soft tissue tumor, an unusual variant of lipoma, consisting of fatty and vascular components and located in the subcutis, usually in the trunk and extremities. We report a case of posterior mediastinal angiolipoma extending into the spinal canal and showing both fat and angiomatous features on CT scan.

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.

Primary germ cell tumors of the mediastinum are rare, accounting 1-5 % among all germ cell tumors and 10% of all neoplasms in this area. Approximately 85 % of these tumors occur in men with a mean age 29 years. 'These tumors are mainly found in the anterior mediastinum and appear grossly as large lobulated masses. They are frequently invasive at the time of diagnosis and almost 90% of patients are symptomatic. Primary nonseminomatous germ cell tumor arising in the posterior mediastinum is very rare. We report a case of 37-year old male arising from the posterior mediastinum. Serum tumors markers including alpha-fetoprotein and $\beta$-hCG which are usually elevated in germ cell tumor were not elevated. He was found to have a primary mediastinal embryonal carcinoma with pulmonary metastasis at open exploration. He was treated with debulking surgery and cisplatin-based chemotherapy, died of sepsis after 15 months postoperatively.

We report a case of invasive pulmonary aspergillosis invading the mediastinum and the left atrium. A 70-year-old woman was hospitalized for dyspnea. She had been well controlled for her diabetes mellitus and hypertension. The chest X-ray disclosed mediastinal widening, and the computed tomography scan of the chest showed that there was a large mediastinal mass and this lesion extended into the left atrium and right bronchus. The cardiac echocardiography showed that a huge mediastinal cystic mass compressed in the right atrium and a hyperechoic polypoid lesion in the left. The pathology from the bronchoscopic biopsy observed abundant fungal hyphae which was stained with periodic acid-Schiff and Gomori's methenamine silver. Despite the treatment with antifungal agents, she died from cardiac tamponade after three months. Invasive pulmonary aspergillosis, which involves the mediastinum and the heart, is very rare in immunocompetent patients.
