Cardiac Relapse of Acute Myeloid Leukemia after Allogeneic Hematopoietic Stem Cell Transplantation.

Secondary or metastatic cardiac tumors are much more common than primary benign or malignant cardiac tumors. Any tumor can cause myocardial or pericardial metastasis, although isolated or combined tumor invasion of the pericardium is more common. Types of neoplasia with the highest rates of cardiac or pericardial involvement are melanoma, lung cancer, and breast and mediastinal carcinomas. Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults. Initial treatment involves chemotherapy followed by consolidation treatment to reduce the risk of relapse. In high-risk patients, the treatment of choice for consolidation is hematopoietic stem cell transplantation (HSCT). Relapse of AML is the most common cause of HSCT failure. Extramedullary relapse is rare. The organs most frequently affected, called "sanctuaries," are the testes, ovaries, and central nervous system. We present a case with extramedullary relapse in the form of a solid cardiac mass.

Severe ifosfamide-induced neurotoxicity: a case report.

INTRODUCTION: Ifosfamide is an alkylating agent used in the treatment of several neoplasias. Ifosfamide metabolites accumulation can produce neurotoxicity, which sometimes manifests as a severe clinical picture. CASE DESCRIPTION: We describe the case of a male with a mixed cellularity subtype classical Hodgkin's lymphoma, treated with ifosfamide after other chemotherapy drugs failure. After the first Ifosfamide cycle, the patient showed severe neurological toxicity that resolved 3 weeks later with supportive therapy. DISCUSSION: Among the risk factors described in the literature, our patient had previously received cisplatin chemotherapy, had low albumin serum levels, and had received ifosfamide as a rapid intravenous infusion. The management of the neurotoxicity is symptomatic although some drugs, like methylene blue and albumin, have also been used. CONCLUSION: This case highlights that clinicians should be aware of the possibility of severe neurological toxicity after the administration of ifosfamide and may control the risk factors associated.
