Extensive bone marrow necrosis and symptomatic hypercalcemia in B cell blastic transformation of chronic myeloid leukemia: report of a case and review of the literature.
Extensive bone marrow necrosis and symptomatic hypercalcemia have been described independently as rare complications of chronic myeloid leukemia. Here we report a 66-year-old man who developed B cell blastic transformation 10 years after diagnosis of CML in the chronic phase. Extensive bone marrow necrosis and symptomatic hypercalcemia concurrently developed after transformation, with development of disseminated intravascular coagulation and multifocal osteolysis. Most necrotic cells were readily identifiable as blasts. Mediators related to hypercalcemia, including prostaglandin E2, transforming growth factor-alpha and transforming growth factor-beta, were significantly elevated in the serum. As far as we know, this is the first case report of chronic myeloid leukemia concurrently developing bone marrow necrosis and hypercalcemia; this association was not reported in other types of leukemia or bone marrow malignancies.
