Burkitt Lymphoma Presenting With Intracardiac Mass and Tumor Thrombosis in the Anterior Mediastinum With Literature Review

: Burkitt lymphoma manifesting as an intracardiac mass is a rare entity. This report describes the case of a 10-year-old boy who presented with an intracardiac mass and tumor thrombosis in the anterior mediastinum that proved to be Burkitt lymphoma. The LMB-96 chemotherapy protocol was given and at the end of the treatment there was still residual mass. A biopsy was performed and the pathology revealed thymus tissue. The patient has been in complete remission for 3 months. Burkitt lymphoma has a short doubling time and an intracardiac lesion can become life threatening. Early recognition and prompt treatment are crucial in achieving optimal outcomes.
