plasmacytoma of the tongue base: A case report and clinical review of head and neck plasmacytoma.
14) Several of the cases demonstrated a soft tissue mass as an extramedullary
extension of intramedullary osteolysis, which displaced surrounding structures.
haematopoiesis (EMH) is a rare cause of spinal cord compression.
Other findings included atrophy of fat stores; pancreatic atrophy; mild periportal hepatitis with extramedullary
hematopoiesis; hypertrophied interrenal cells in the adrenal gland consistent with stress; passive congestion of the lung; and congestion, hemorrhage, and compression atrophy of renal tissue.
Philadelphia-negative chronic myeloproliferative disorders (CMDs) are characterized by clonal proliferation of hematopoietic progenitor cells in the bone marrow and by extramedullary
hematopoiesis associated with increased [CD34.
Magnetic resonance imaging (MRI) of the spine revealed an intradural, extramedullary
, 16-mm enhancing mass in the left half of the bony canal at the T10 to T11 level.
plasmacytoma is known to comprise 4% to 6% of all plasma cell neoplasms.
11), (15), (16) In patients with fully developed disease bone marrow is replaced by fibrous connective tissue, causing extramedullary
In rare cases, melanin and extramedullary
hematopoiesis may be seen.
deformities include a variety of femoral shaft problems, such as angular, rotational, translational, and longitudinal discrepancies.
hematopoiesis mimicking hepatocellular carcinoma
In the spine, extramedullary
haematopoeis is most commonly located in the lower thoracic and upper lumbar regions.
