Thymomas and thymic carcinomas are rare mediastinal tumors. Ectopic middle mediastinal thymomas/thymic carcinomas are even more rare. We report the first case of B3/thymic carcinoma borderline tumor of the middle mediastinum in a 61-year-old myasthenic woman. Preoperative chest tomography and magnetic resonance imaging documented a 4.0 × 3.5 × 2.7 cm mass in the retroinnominate space. A resecti...

Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...

Carcinoid tumor of the thymus is a rare neoplasm. It comprises a wide spectrum of lesions ranging from well-differentiated to poorly-differentiated neoplasms. We report a case of anterior mediastinal mass, which is proven to be an atypical thymic carcinoid tumor with a histopathological nature of intermediate-grade moderately-differentiated neuroendocrine carcinoma. We also present the patient’...

There is a well-known association in male patients between mediastinal germ cell tumors (GCT) and hematologic malignancies, with a propensity towards acute megakaryoblastic leukemia. These rare malignancies have been shown to share a common clonal origin, often deduced from the finding of isochromosome 12p, i(12p), in cells from both the solid tumor and the leukemia, and thus are now known to r...

abstract background the aim of this study was to evaluate sensitivity and specificity of mediastinal sonography, and compared with ct, in detection of anterior mediastinal neoplasms. materials and methods the sonography with convex probes (5.0 and 7.5 mhz) was done prospectively for 34 patients (from 2 to 25 years old) with mediastinal mass. the results were compared with the results of contras...

Pleuropulmonary blastoma (PPB) is a rare malignant dysontogenetic neoplasm primarily affecting children and is characterized histologically by a variably mixed blastematous and sarcomatous patterns. We herein report a very exceptional adult case of PPB. A 21-yr-old male patient presented with a left chest pain of two weeks' duration. A computed tomography scan revealed a large, multicystic tumo...

BACKGROUND There are some reports in the literature, which suggest that cardiac tamponade drainage may transiently affect systolic function and also cause acute respiratory distress syndrome (ARDS). We did not find any reports of acute ventricular failure and ARDS secondary to mediastinal tumor resection without tamponade. CASE REPORT Here we report a 48-year-old woman presenting with massive...

malignant germ cell tumors, and it most frequently occurs in the anterior mediastinum in the chest (1). The posterior mediastinum is a rare site of origin for seminoma, and prominent cystic change of a posterior mediastinal seminoma has not been previously described. The present report describes the CT, MR and F-FDG PET/CT findings of a case of a primary posterior mediastinal seminoma that was ...

We report a case of ectopic middle mediastinal thymoma in an asymptomatic 50-year-old woman.Chest X-ray, CT, MRI and FDG-PET/CT examinations were performed preoperatively. The tumor was removed by video-assisted thoracic surgery, and the pathological diagnosis was type B3 thymoma of the World Health Organization classification and stage II thymoma of the Masaoka clinical staging system.Postoper...

Desmoid tumors (DTs) are a group of rare and benign soft tissue tumors that result from monoclonal proliferation of well-differentiated fibroblasts. Since DTs tend to infiltrate and compress adjacent structures, the location of DTs is one of the most crucial factors for determining the severity of the disease. Furthermore, DTs can further complicate the clinical course of patients when the grow...
