OBJECTIVES To review our results with elective superior mediastinal dissections for thyroid carcinomas. STUDY DESIGN Retrospective review. METHODS We searched operative case logs for all patients with thyroid carcinoma treated with an elective superior mediastinal dissection by the senior author (Y.D.) during a 6-year period. Charts were reviewed for demographic information and pathologic r...

Liposarcomas are malignant tumors of mesenchymal origin and one the most common human soft tissue sarcomas. Primary mediastinal liposarcomas, first mentioned in 1939, account for less than 1% all tumors, whereas primary liposarcomas approximately localizations. Mediastinal a heterogeneous group with different morphology, which often characterized by aggressive disease course leading to patient’...

Primary dedifferentiated liposarcoma originating in the mediastinum is extremely uncommon. Here, we report a case of mediastinal dedifferentiated liposarcoma. A 74-year-old man was admitted to our hospital with a left intrathoracic tumor ∼10 cm in diameter. Computed tomography that was taken in another hospital 2 years before the initial visit to our hospital had shown a lipomatous tumor ∼3 cm ...

PURPOSE The diagnosis and staging of lung cancer critically depends on surgical procedures. Endoscopic ultrasound (EUS) -guided fine-needle aspiration (FNA) is an accurate, safe, and minimally invasive technique for the analysis of mediastinal lymph nodes (LNs) and can additionally detect tumor invasion (T4) in patients with centrally located tumors. The goal of this study was to assess to what...

A perivascular epithelioid cell neoplasm (PEComa) in the chest is rare, let alone in the mediastinum and lung. A 63-year-old man was admitted to our hospital with chest pain for more than 2 months and was found to have an opacity in his mediastinum and lung for 3 weeks. Enhanced chest computed tomography (CT) revealed a mass in both the left upper lobe and central anterior mediastinum. To ident...

introduction although thymoma is the most common anterior mediastinal tumor, only 5% of thymoma cases develop pure red cell aplasia (prca). case presentation in this article we have reported a 59-year-old man with a large anterior mediastinal mass (diameter of 10 cm) and severe anemia, that thymoma and pure red cell aplasia have been demonstrated by histopathologic and hematological examination...

Inf lammatory myof ibroblast ic tumor is an unusual disease that is most commonly seen in the lung and orbit and extremely rare in the mediastinum. As far as we know, there have been only two case reports of mediastinal inf lammatory myofibroblastic tumor occurring in patients over 40 years old. In literature, we found no such case of mediastinal inf lammatory myof ibroblastic tumor that can pr...

 Introduction:Mediastinum contains different vital structures that are located in the anterior and middle or posterior compartments. Various types of mediastinal masses or tumors can be seen in the mediastinum. Materials and Methods:This case series study was performed on 95 patients who had referred to Mashhad University of Medical Sciences between 1990 and 2010 were reviewed. The Inclusion cr...

Teratoma of mediastinum is rare germ cell tumor. Anterior mediastinum is the most common extragonadal site. Benign mediastinal teratoma accounts for 60% of all mediastinal germ cell tumors. Benign mature teratoma has excellent prognosis after surgical excision. We present a case of 20-year-old woman diagnosed as benign mature teratoma which compressed main pulmonary trunk. The patient underwent...
