Myeloid sarcomas, extramedullary
lesions composed of myeloid lineage blasts, typically form tumors that may precede, follow, or even occur in the absence of systemic AML.
Solitary collections of monoclonal plasmacytomas may originate from soft tissues and are called extramedullary
plasmacytomas (EP) (VAIL, 2013).
The two primary options for treatment of proximal femoral fractures are intramedullary fixation and extramedullary
These patients were predominantly in an early International Staging System stage, showed non-secretory and light-chain variants, and significant association with extramedullary
3 These are present at three sites, intraosseous, intraspinal extramedullary
Spinal tumors in neurofibromatosis type 2 (NF-2) can be intramedullary, extramedullary
, or associated with the nerve roots, and there may be multiple tumors at multiple locations in the spine.
His topics include congenital and developmental abnormalities of the spinal cord or vertebrae, intradural intramedullary lesions (spinal cord lesions), dural and intradural extramedullary
lesions, multifocal lesions and/or poorly defined signal abnormalities involving the spine, and traumatic lesions involving the spine.
plasmacytoma (SEP) is a neoplastic proliferation of a single clone of plasma cells that occur outside of the bone and bone marrow.
The presence of leukemia cutis suggests extramedullary
involvement, thereby indicating a poorer prognosis.
The findings also highlight a possible pathway for this relationship, suggesting that stress-related noradrenalin stimulates extramedullary
hematopoiesis, a key driver of inflammation.
However, 3% of cases may develop extramedullary
involvement, defined as the formation of solid plasmacytomas outside the bone marrow.
Moreover, hematological abnormalities such as thrombocytopenia, anemia, susceptibility to infections, and extramedullary
hematopoiesis can result because of the decrease in hematopoietic cells.
