Abstract

Myeloid sarcoma is an extramedullary manifestation of haematologic malignancy, most commonly acute myeloid leukemia (AML), which can cause neurological symptoms. A 45-year-old male with a history of AML presented with a lumbosacral nerve root entrapment syndrome followed by cauda equina compression, but without systemic signs of AML recurrence. MRI showed a mass compressing the spinal cord at level L5-S2. After surgically removing the tumour pathologic examination yielded a myeloid sarcoma. Combined chemotherapy and radiation therapy followed. Five months later the patient developed a thoracal (Th10-Th11) radiculopathy due to a relapse of the myeloid sarcoma, followed by C8-Th1-radiculopathy caused by leptomeningeal spread. This case forms the first description of recurrent, multifocal and progressive radiculopathy due to myeloid sarcoma. This diagnosis should be considered in patients with radiculopathy with previous haematological malignancy and/or signs or symptoms of such disease; the absence of systemic disease activity does not rule out myeloid sarcoma.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
