Background: Tumor lysis syndrome (TLS) is a potentially fatal complication of cancer therapy characterized by severe electrolyte and metabolic abnormalities such as hyperphosphatemia, hyperkalemia, and hypocalcaemia. TLS usually occurs in aggressive hematologic malignancies such as Burkitt lymphoma and acute leukemia. TLS has rarely been observed in multiple myeloma (MM).

Dasatinib-induced immune mediated-thrombotic thrombocytopenic purpura.

Most commonly seen side effects with Tyrosine kinase inhibitors (TKI's) are hematologic toxicities. Besides, with dasatinib autoimmune side effects can be seen. Thrombotic thrombocytopenic purpura (TTP) is a life- threatening disease that can be related to various causes mainly autoimmune disorders or antineoplastic drugs.

Isolated Breast Relapse of Acute Lymphoblastic Leukemia After Allogeneic Hematopoietic Stem Cell Transplantation.

Isolated breast relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is less often seen. Chronic graft-versus-host disease (cGVHD) is effective in preventing marrow relapse, but cGVHD seems not to be effective extramedullary relapse (EMR). We report the case of isolated breast relapse after first allo-HSCT for acute lymphoblastic leukemia (ALL).
