Hypercalcemia with multiple osteolytic lesions and increased circulating tumor necrosis factor in an adult patient with B-cell acute lymphoblastic leukemia

Abstract

Introduction: Acute lymphoblastic leukemia (ALL) is very rarely presented with diffuse osteolytic lesions and hypercalcemia.

Case outline: We report a 28-year-old male with the B-cell ALL who presented with extensive osteolytic lesions, bone pain, hepatosplenomegaly, and pancytopenia without circulating blasts in peripheral blood. An increased serum level of tumor necrosis factor (TNF-α) was registered while the levels of IL-1α and IL-1β were normal. The patient failed to achieve remission on two induction regimens but achieved one after the successful allogeneic stem cell transplantation, which lasted for six months, after which he developed a relapse and died.

Conclusion: The presented case may serve as a clinical demonstration of possible involvement of TNF-α as a pathogenic factor in the evolution of osteolytic lesions that are occasionally observed in patients with ALL. This might have relevance in the management of such patients as chemotherapy alone may not represent the beneficial option in this clinical context.
