Abstract INTRODUCTION T cell dysfunction contributes to immune escape in patients with cancer and is particularly severe CNS tumors. sequestration a contributing mechanism of lymphopenia lymphoid organ contraction occurring treatment naive mice Glioblastoma. Our group demonstrated that this phenomenon mediated by loss S1P1 surface expression on T-Cells within the bone marrow. We murine models r...
Bone Marrow Edema Syndrome (BMES) is an uncommon, self-limited and with unknown etiology characterized by severe pain with no history of trauma. Due to low prevalence of BMES and its non-specific signs, correct diagnosis is often delayed intensifying bone pain and impairing patients’ function and quality of life. In this study we treated a patient with bone marrow edema syndrome in right a...
Extramedullary hematopoiesis is an extension of marrow beyond its bony casement. It is associated with a number of diseses when the normal function of marrow is disturbed. A large accumulation of extramedullary hematopoiesis may occur at the paravertebral area, mediastinum, spleen and liver. Intrarenal extramedullary hematopoiesis is rare.Only a few cases have been reported of myelofi...
Osteopetrosis is a rare metabolic bone disease characterized by generalized increase in skeletal mass. About 500 cases have been described in the literature. This disorder presents. In one of three forms: Osteopetosis Tarda , Osreopetrosis Congenital and “marble bone” disease. Osteopetrosis congentia results in bone marrow failur and is almost always fatal. Marble bone disease causes short st...
Primary myeloid sacrom (MS) is a rare tumor and even more rare in multiple organs with no evidence of bone marrow involvement. This report describes an unusual case of a 19-year-old male presenting scrotal MS with a history of subconjunctival MS, 5 months ago. Bone marrow biopsies showed no evidence of acute leukemia. Despite radiotherapy for first involvement and chemotherapy for second presen...
The normal bone marrow has three primary components: osseous matrix, red marrow, and yellow marrow. The osseous components of the marrow are the trabeculae of cancellous bone, which provide the supporting framework for the red and yellow marrow elements. The red or cellular marrow is hematopoietically active, producing RBCs, WBCs, and platelet precursors. Hematopoietically inactive yellow marro...
