If a surgeon decides to approach a mediastinal mass thorascopically, they must ensure that adequate specimens are obtained as up to 50% of mediastinal cases required a second diagnostic biopsy when a thoracoscopic biopsy was performed.Non-Hodgkin Lymphomas (NHL) are a varied group of tumors with almost 60 unique subtypes, accounting for 7% of tumors and are typically high grade.For the Burkitt lymphoma, the prognosis is dependent on the extent of disease rather than on completeness of surgical resection.
