A 24-year-old man was admitted to the hospital for pancytopenia. Peripheral blood test and bone marrow aspiration demonstrated an increase in hypogranular promyelocytes. Karyotype analysis and RT-PCR showed 47, XY, t(15;17)(q22;q12), +12, and PML-RARA, respectively. The patient was diagnosed as having acute promyelocytic leukemia microgranular type (M3v) and was therefore administered all-trans retinoic acid (ATRA). Idarubicin and Ara-C were later added to the treatment regimen because of an increased number of leukemic cells. Nausea, vomiting and general fatigue associated with hypercalcemia developed on day 30. There were no findings indicating infection. The administration of ATRA was thus suspected to have induced hypercalcemia. ATRA was therefore discontinued and prednisolone and elcatonin were administered instead. Five days after this change, the serum calcium level normalized. Complete remission was thereafter confirmed on day 45. Hypercalcemia associated with ATRA therapy for APL is rare, and to date, there have been no case reports describing hypercalcemia associated with M3v in the literature. Interaction of fosfluconazole was suspected of causing hypercalcemia when used concomitantly with ATRA.

A 55-year-old woman developed acute promyelocytic leukaemia during treatment with all-trans-retinoic acid and arsenic trioxide. Initially, she presented with symptoms of epigastric pain, vomiting, and nausea, and she developed acute pancreatitis. She was treated with parenteral nutritional supplementation for 20 days. However, the patient continued to develop refractory hyponatraemia, hypotension, and apathy. Finally, the patient was diagnosed with Wernicke encephalopathy (WE) using head magnetic resonance imaging. The patient underwent high-dose intravenous thiamine administration, and her symptoms were alleviated. WE is a rare adverse event during acute pancreatitis therapy. Acute pancreatitis that is caused by all-trans-retinoic acid and arsenic trioxide is a rare complication of acute promyelocytic leukaemia during chemotherapy. Further study is essential to improve our comprehension of the risk factors for complications in patients with acute promyelocytic leukaemia, considering that the associated complications were potentially caused by multiple etiological factors. A better understanding of these risk factors may help to improve the prognosis of patients with acute promyelocytic leukaemia at an early stage.
