A Case of Chronic Myelomonocytic Leukemia: the Onset of which was Manifestedby Hypokalemia and Hypocalcemia

Abstract

Intractable hypokalemia and hypocalcemia are rare complications in leukemia patients. This article reports a patient with chronic myelomonocytic leukemia (CMML)with refractory hypokalemia, hypocalcemia, hypochloridemia, hypomagnesemia-a 48-year-old man complained of fatigue, nausea, and face numbness for over one month. The number of monocytosis in peripheral blood and bone marrow increased remarkably. At the same time, the patient developed hypokalemia, hypochloridemia, hypocalcemia, hypomagnesemia, metabolic alkalosis, massive proteinuria, and increase in plasma aldosterone and renin. After two coursea of treatment using Azacitidine therapy, complete remission of bone marrow was achieved and the electrolyte disturbance was almost corrected, except hypomagnesemia. We summarize the clinical characteristics of the patient so as to raise the clinical awareness of such cases.
