A Case of Mediastinal T-cell Lymphoblastic Lymphoma Causing Superior Mediastinal Syndrome and Severe Complications
A 3-year-old girl with T-cell mediastinal lymphoma causing superior mediastinal syndrome is described. The patient underwent biopsy under general anesthesia and received respiratory support thereafter. Intensive multi-agent chemotherapy was administered to cover malignancies other than malignant lymphoma and to overcome the life-threating complication. As a result, the patient developed tumor lysis syndrome in spite of prophylaxis. In addition, invasive fungal infection developed because of prolonged neutropenia. However, the patient recovered and achieved complete remission. When making treatment decisions for this condition, it is important to establish a diagnosis as soon as possible using a minimal degree of invasion.
