Case report of precursor B-cell lymphoblastic lymphoma presenting as syncope and cardiac mass in a nonimmunocompromised child

Pediatric Cardiac Lymphoblastic Lymphoma: A Case Report and Review of the Literature

Cardiac lymphoma is rare in children. Treatment typically includes chemotherapy, combination of radiotherapy, or surgery. We report a case of stage IV precursor B lymphoblastic lymphoma with secondary involvement of the heart in an 11-year-old girl who was treated with acute lymphoblastic leukemia-based chemotherapy. Also, we review the literature on this uncommon malignancy.

Cardiac Infiltration as the First Manifestation of Acute Lymphoblastic Leukemia: A Systematic Review

Cardiac symptoms or signs as the first manifestations in acute lymphoblastic leukemia patients are sporadically reported which lead to misdiagnosis or delayed diagnosis due to lack of clinical experience and improper diagnosis procedures. Here, we documented the clinical features, procedures of diagnosis, treatments, and outcomes from the so-far reported 30 lymphoblastic leukemia cases that initially presented as cardiac problems and provided management recommendations based on the experiences and lessons learned from these patients to help physicians avoid misdiagnosis and improper treatment.

Precursor B-lymphoblastic lymphoma involving an intracardiac mass and myocardial infiltration: a case report

We report the case of a 17-year-old man with precursor B-lymphoblastic lymphoma involving an intracardiac mass and myocardial infiltration. Intensified chemotherapy followed by autologous peripheral blood stem cell transplantation resulted in long-term complete remission for over 5 years. As the most frequent sites of B-lymphoblastic lymphoma involvement are the skin, soft tissue, bone, and lymph nodes, reports of cases harboring cardiac involvement are relatively few. This is a rare case of B-lymphoblastic lymphoma displaying cardiac involvement, in which cardiac infiltration was one of the initial manifestations.

[Malignant primary cardiac tumors in childhood and adolescence]

Primary heart tumors are uncommon in children. The majority of them are benign, with only 10% malignant. Among malignant cardiac tumors, sarcoma (rhabdomyosarcoma, angiosarcoma, synovial sarcoma) and lymphoma (Burkitt's lymphoma, large B-cell lymphoma, lymphoblastic lymphoma) predominate. There are few published pediatric series on malignant primary cardiac tumors. We report here 3 observations of primary malignant cardiac tumors, 2 cases of sarcoma (angiosarcoma and synovial sarcoma) and 1 case of Burkitt's lymphoma. A precise pathological diagnosis is necessary for the proper management of these patients. For sarcoma, treatment associates surgery and chemotherapy. Surgery should be as complete as possible because of the lack of chemotherapy sensitivity of some sarcomas, mainly angiosarcoma and synovial sarcoma. Therefore, the prognosis of cardiac sarcoma remains poor. For primary cardiac lymphoma, management should not be different from lymphoma in other locations. Chemotherapy is the main treatment, and surgery has to be used only when complications occur. Prognosis depends on histology and not lymphoma location, and so is better than the prognosis for sarcoma.
