Hemangioma in the anterior mediastinum
The Japanese Journal of Thoracic and Cardiovascular Surgery, 2003Anterior mediastinal hemangiomas are very rare neoplasms in mediastinal tumors. A 58-year-old woman was revealed to have a mass measuring 4 x 3 cm in size in the anterior mediastinum with calcification on computed tomography. It was initially suspected to be a thymoma. We performed tumor extirpation in November 1998.

Lymphomas of the Anterior Mediastinum
Seminars in Pediatric Surgery, 1999Lymphomas are the most common cause of masses in the pediatric mediastinum. More than 50% of children with lymphoblastic lymphoma present with an anterior mediastinal mass, and more than one third of all patients with non-Hodgkin's lymphoma have their primary sites in the mediastinum. Hodgkin's disease also frequently involves this anatomic compartment

Seminoma of the Anterior Mediastinum
The Annals of Thoracic Surgery, 1975Primary pure cell seminoma of the mediastinum is a rare and potentially fatal lesion. Encroachment on or invasion of adjacent structures is common, as are distant metastases. The differentiation between pure cell seminomas and mixed germ cell tumors should be made since the extreme radiosensitivity of seminomas improves the prognosis.

Thymolipoma of Anterior Mediastinum
Asian Cardiovascular and Thoracic Annals, 1999Thymolipoma is a very rare benign anterior mediastinal tumour. Most patients are asymptomatic but a few may present with clinical symptoms attributable to its huge size or less frequently, with myasthenia gravis. We report a case of huge thymolipoma occupying almost two thirds of the thorax in a 25-year-old female, which caused collapse of the lower ...

Arteriovenous Malformation in the Anterior Mediastinum
The Annals of Thoracic Surgery, 2010Arteriovenous malformations of the mediastinum are exceedingly rare. A literature search found fewer than 10 reported cases of congenital, posterior mediastinal arteriovenous malformations in adults. We describe a giant anterior mediastinal arteriovenous malformation in a 29-year-old man.

Cystic paraganglioma of the anterior mediastinum
Annals of Diagnostic Pathology, 2010Paraganglioma of the mediastinum is an extremely uncommon neoplasm, and the concurrent finding of cystic changes has yet to be reported in the literature. We report a case of a 43-year-old man presenting with chest pain and left arm paresthesias. Imaging studies revealed a well-defined cystic lesion located in the anterior mediastinum, with the patient

Ectopic pancreas in the anterior mediastinum
The Japanese Journal of Thoracic and Cardiovascular Surgery, 2005We report an uncommon clinical case of anterior mediastinal localization of ectopic pancreatic tissue. A 39-year-old male was referred to our institution for investigation of an abnormal mediastinal shadow on a chest X-ray, and a large cystic lesion measuring 10 x 8 cm located in the anterior mediastinum was observed on a computed tomographic scan.
