PY - 2014 T2 - Operative Pediatric Surgery, 2e AB - Staging laparotomy is no longer necessary for work-up of lymphomas.Hodgkins Disease accounts for 6% of pediatric malignancies and is the most commonly diagnosed cancer among adolescents aged 15 to 19.The initial step to diagnosis of the Hodgkin lymphoma is lymph node biopsy. 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.
