Bone marrow necrosis

Abstract

Bone marrow necrosis is most frequently diagnosed at postmortem examination. Antemortem diagnosis is still uncommon. In a recent review of world literature, we have found 133 cases of bone marrow necrosis diagnosed during life. It has been observed during the course of a wide variety of diseases, most commonly in association with acute and chronic leukemia, carcinoma, malignant lymphoma, infections, and sickle cell disease. We report two intravitally diagnosed cases of bone marrow necrosis occurring in two patients with high-grade B-cell lymphoproliferative disease. These cases are unusual in that both patients had a triad of bone marrow necrosis, high-grade B-cell lymphoproliferative disease, and hypercalcemia. Despite chemotherapy, both cases ultimately proved fatal, with progressive involvement of the central nervous system.
